MOTION FOR LEAVE TO FILE
PETITION FOR WRIT OF PROHIBITION
_________________________________

TO THE HONORABLE JUDGES OF THE COURT OF CRIMINAL
APPEALS:

Undersigned counsel represents David R. Dow in proceedings before

this Court and yesterday filed an emergency motion for stay on Dow’s

behalf in cause number WR-61,939-01. As the Court is aware, Dow

represents Robert Lynn Pruett who is scheduled to be executed on April 28,

2015. Dow is actively pursuing relief for Pruett and has filed two petitions
for a writ of certiorari in the Supreme Court of the United States, both of

which are currently pending. See Pruett v. Texas, No. 14-8837 (U.S. filed

Mar. 10, 2015); Pruett v. Texas, No. 14-8097 (U.S. filed Jan. 20, 2015).

Dow has prepared a petition for a writ of prohibition to be filed in this

Court on behalf of Pruett. As the Court is aware, pursuant to the Court’s

order of January 14, 2015, Dow cannot practice in this Court on behalf of

the clients he represented on that day (of which Pruett is one) without first

obtaining leave. In re Dow, Nos. WR-61,939-01, WR-61,939-02, at *3

(Tex. Crim. App. Jan. 14, 2015).

Counsel therefore respectfully prays the Court grant Dow leave to file

the petition for a writ of prohibition attached as Exhibit 1 on behalf of

Robert Lynn Pruett.

PETITION FOR WRIT OF PROHIBITION
_________________________________

TO THE HONORABLE JUDGES OF THE COURT OF CRIMINAL
APPEALS:

STATEMENT OF THE CASE

On April 23, 2002, Robert Lynn Pruett was convicted of killing Daniel

Nagle, a correctional officer at the McConnell Unit, where Pruett was incarcerated.

The State’s theory at trial was that Pruett killed Nagle because he was upset that

Nagle had written him up for carrying a sandwich into an area where inmates were

not to take food. Torn pieces of the disciplinary report were found near Officer
Nagle’s body. While blood on the disciplinary report was tested for DNA and

found to belong to Officer Nagle, no other DNA profiles were developed from the

report.

With no physical evidence linking Robert Pruett to Daniel Nagle’s murder,

the State was forced to rely on testimony from witnesses to persuade Pruett’s jury

to believe its theory and convict Pruett of capital murder. This testimony came

from informants who were incarcerated with Mr. Pruett – many of whom, we now

know, received special treatment in exchange for their testimony – and Nagle’s co-

workers.

Any number of people could have had a motive for wanting Daniel Nagle

dead. Nagle was an important officer and was head of the correctional officers

union. In the months leading up to his death, Nagle was in the process of preparing

a lengthy grievance against the Texas Department of Criminal Justice (TDCJ) in

which he complained, among other things, about corrupt senior officers. This

complaint was subsequently revealed to be compelling; approximately one month

after Nagle was killed, three correctional officers that worked at the McConnell

Unit were indicted on felony bribery charges after being accused of agreeing to

launder drug money for inmates.

Not only had Mr. Pruett consistently maintained his innocence from the time

of his arrest, and not only did the State withhold evidence it had both coerced

2
witnesses favorable to Mr. Pruett not to testify while also offering secret deals to

inmates in return for their testifying against Mr. Pruett, but the indictment of other

corrections officers dramatically increased the plausibility that Mr. Pruett had been

framed for a murder that had in fact been carried out by someone with animus

toward Officer Nagle. Consequently, believing that the person who tore up the

disciplinary report in an attempt to frame Robert Pruett for the murder of Daniel

Nagle might have left a sufficient amount of epithelial cells on the report to allow

for the creation of a DNA profile that would aid in identifying the actual murderer,

undersigned counsel moved the trial court below to order testing using techniques

not available at the time of Pruett’s trial.

The results of that testing demonstrated that DNA was present on the report.

However, after thirteen years of being stored in a manner inconsistent with the

Texas Department of Public Safety’s Physical Evidence Handbook, the report did

not contain a sufficient amount of DNA to develop a complete profile. The pieces

of the report were stored in – and continue to be stored in – plastic bags. The DPS

Handbook mandates that evidence containing biological evidence not be kept in

plastic bags. This is because plastic bags provide a growth medium for bacteria

that may degrade DNA evidence. In short, by not following its own protocol, the

State of Texas destroyed the evidence that could have exonerated Mr. Pruett. And

the State now intends to execute Mr. Pruett, not because DNA evidence establishes

3
his guilt, but because, likely owing to the improper storage of the torn pieces of the

report, there is no longer a sufficient amount of DNA to create a complete genetic

profile that would allow identification of the actual murderer.

By enacting Chapter 64 of the Texas Code of Criminal Procedure, which

permits post-conviction testing of potentially exculpatory biological evidence, the

State of Texas created a procedure that vested Robert Pruett with a liberty interest

in demonstrating his innocence. Yet by ignoring its own guidelines for the

preservation of biological evidence and thereby allowing the pieces of the report to

degrade to such a degree that they no longer contain adequate material to aid in

identifying the actual murderer, Mr. Pruett’s right to fundamental fairness, and to a

reliable sentence, have been abridged.

On December 17, 2014, Judge Bert Richardson ordered the Director to

“carry out [Pruett’s] sentence of death by intravenous injection of a substance or

substances in a lethal quantity sufficient to cause” Pruett’s death. Corrected Third

Order Setting Execution, State v. Pruett, No. B-01-M015-0-PR-B (156th Dist. Ct.,

Bee County, Tex. Dec. 17, 2014) (attached as Exhibit A). Allowing the State to

execute Pruett only after the State’s conduct has prevented Pruett from

demonstrating his actual innocence would violate the Fourteenth Amendment’s

Due Process Clause (attached as Exhibit B) and the Eighth Amendment’s

protection against cruel and unusual punishment (attached as Exhibit C). Pruett

4
respectfully prays this Court enter an order prohibiting the Director from carrying

out Judge Richardson’s order because to execute Pruett would be to violate the

mandates of the Eighth and Fourteenth Amendments.

STATEMENT OF JURISDICTION

This Court has the authority to grant an application for writ of prohibition

under Article 5, section 5 of the Texas Constitution. Because Pruett’s claim does

not challenge the legality of his conviction or sentence but rather challenges the

constitutionality of his execution, it is properly presented in a petition for a writ of

prohibition. See Ex parte Chi, 256 S.W.3d 702, 702-03 (Tex. Crim. App. 2008);

Ex parte Alba, 256 S.W.3d 682, 685-87 (Tex. Crim. App. 2008).1

ISSUE PRESENTED

The specific issue presented in this petition for a writ of prohibition is as

follows: Because Texas has given death-sentenced inmates the right to pursue

exoneration through the forensic testing of biological evidence, do either the

Eighth or Fourteenth Amendments of the United States Constitution require the

1
While Chi and Alba were concerned with the constitutionality of the lethal injection
protocol, the claims raised in these cases are similar to Pruett’s because it does not challenge the
lawfulness of his conviction or sentence (though Pruett is challenging the constitutionality of
both his conviction and sentence in parallel litigation). Pruett’s claim challenges the subsequent
act of the State not properly preserving evidence, which has interfered with his ability to prove
his innocence, notwithstanding the lawfulness of the original trial proceedings. Moreover, this
Court, in an unpublished opinion, has recently cited Alba for the proposition that a claim that
alleges the State failed to properly preserve biological material is not cognizable in habeas. Ex
parte Fuller, No. WR-16,531-09, 2014 WL 1328345, at *2 (Tex. Crim. App. Apr. 2, 2014).

5
State to properly preserve potentially exculpatory biological evidence in all capital

cases, at least until sentence is carried out?

STATEMENT OF FACTS

At the time the murder giving rise to this case occurred, Robert Pruett was

serving a 99-year sentence. At the age of 17, he was convicted as a party to a

murder committed by his father when he (Robert Pruett) was only 15 years old.

(His father remains incarcerated for that offense.) Mr. Pruett himself had never

been convicted of committing any violent offense at all, and from the time he was

indicted for capital murder in this case, he steadfastly maintained his innocence.

A. Nagle’s murder and the investigation

Daniel Nagle, a correctional officer at the McConnell Unit was killed on

December 17, 1999. Trial Tr. vol. 42: 236.2 As will be discussed below, there

were people with a motive to kill Officer Nagle, but they did not include Mr.

Pruett.

The physical evidence collected during the investigation was found

primarily in two separate locations. Officer Nagle was killed in the multipurpose

room. The shank that was used to kill him was recovered from that room. Trial Tr.

vol. 42: 274, 320. Pruett’s prints were not found on the weapon. Trial Tr. vol. 44:

2
In this petition, the trial record will be abbreviated as Trial Tr. vol. [number]: [page
number].

6
49. The only DNA profile that could be developed from the weapon was a match

to Officer Nagle. Trial Tr. vol. 42: 337. A blue baseball cap was found in the

toilet of the bathroom inside the multipurpose room. Id. at 322. No physical

evidence connected this item to Mr. Pruett, either. Blood, identified as belonging

to Nagle, was found on the bathroom floor. Id. at 322-23, 357. Keys were found

on the bathroom floor. Id. at 327-28. No blood belonging to Pruett was anywhere

on Nagle or his clothes, Trial Tr. vol. 44: 49, nor was any of Officer Nagle’s blood

found on Pruett or anything (including clothes) connected to him. Trial Tr. vol. 42:

346-47, 360. In other words, and in short, not a single iota of physical evidence

connected Mr. Pruett to this crime.

The disciplinary report found near Officer Nagle’s body had been torn into

seven pieces and was scattered on the floor of the bathroom inside the

multipurpose room. Trial Tr. vol. 42: 331-33. Officer Chris King collected the

pieces of the report and placed them in paper sacks. Id. at 276-77.3 The

disciplinary report contained biological material. According to Lisa Harmon

Baylor of the DPS lab in Corpus Christi, Texas (who performed forensic testing

pretrial), one piece of the report had blood. Id. at 366. The blood that was tested
3
It is not clear from the record or the pictures of the evidence whether Officer King
placed the pieces of paper in plastic bags before placing them in the paper sacks or simply placed
the pieces loose in brown paper sacks. It is clear, though, that by February 24, 2000, the evidence
was being stored in plastic bags. Exhibit D (pictures of the evidence displaying the initials CJP
dated 2/24/00 on many of the plastic bags containing the evidence).

7
on the disciplinary report belonged to Nagle. Id.; vol. 52: 83 (State’s Ex. 52 at 6)

(DPS lab report issued by Ms. Baylor on May 25, 2000).4 Ms. Baylor accessed the

evidence around the same time that she issued her report. Exhibit D (containing

the initials LHB with the date 5/23/00 on many of the packages containing the

evidence). Latent prints were found on several pieces of the disciplinary report.

Trial Tr. vol. 43: 41-42; 52: 336 (Def.’s Ex. 6). The prints on the report did not

belong to Pruett. Trial Tr. vol. 44: 49. None of the blood found anywhere in the

multipurpose room belonged to Pruett. Id. Neither the blood on the report nor any

of the other physical evidence collected from the multipurpose room identified

Pruett as having been present there.

Other evidence as well was collected from inside the gymnasium and the

bathroom inside the gymnasium. A pair of pants and a white towel were found in

the trashcan of the bathroom inside the gymnasium. Trial Tr. vol. 42: 341.

Another pair of pants was found in another trashcan outside of the bathroom. Id.

While blood on these items of clothing belonged to Pruett, who had cut his finger

earlier in the day (i.e., prior to the murder of Officer Nagle), none of Officer

Nagle’s blood was found on any of the clothes recovered from the gym area. Id. at
4
While it is not clear in the record where the torn pieces of paper were stored between
the date Ms. Baylor issued her report on May 25, 2000 and when the evidence was returned to
her on June 5, 2013, Exhibit D (containing the initials LHB dated 6/5/13 on many of the
packages containing the torn pieces of paper), it is clear the evidence was not preserved at the
DPS lab. Counsel reasonably believes the evidence was stored in the Bee County Clerk’s office
during this time.

8
346-47, 360.

In addition to the evidence collected in these two areas, blood was found in

the hallway leading to the gym. Trial Tr. vol. 42: 342. Analysts were unable to

determine the source of the blood. Id.

B. Corruption at the McConnell Unit

We now know with certainty that some members of the correctional officers

union – of which Nagle was an officer – were corrupt and engaging in criminal

activity at the time of Officer Nagle’s murder. Significantly, in the months leading

up to his death, Officer Nagle was working on a lengthy grievance against TDCJ.

This grievance complained (among other things) of corrupt senior officers at the

Unit where he worked. See Nate Blakeslee, Shades of Gray: In Texas Prisons, It’s

Hard to Tell Who Your Enemies Are, Austin Chron., Apr. 28, 2000, available at

http://www.austinchronicle.com/news/2000-04-28/77012/.

The grievance he was penning proved to be both shocking and poignant: A

month after Nagle was killed, three correctional officers that worked at the

McConnell Unit were indicted on felony bribery charges after being accused of

agreeing to launder drug money for inmates. Associated Press, 4 state corrections

officers face felony bribery charge: Guards who worked at Beeville-area state

prisons accused of agreeing to launder supposed drug money for convicts, Corpus

Christi Caller Times, Jan. 27, 2000. The evidence that some of these officers may

9
have had a motive to see Officer Nagle dead is not mere speculation; according to

Scott Kimes, who was incarcerated at the McConnell Unit when Nagle was killed,

correctional officers knew that Nagle had been attacked but allowed him to lay in

the multipurpose room dying before they made any effort to save him. Clerk’s R.

vol. 1: 27-28.5

C. Trial

Pruett was indicted on June 26, 2001. Trial began on April 15, 2002.

Because there was no physical evidence linking Pruett to Nagle, the State’s

evidence during guilt/innocence consisted almost entirely of testimony form

correctional officers and inmates. Because no correctional officers claimed to have

witnessed the attack, the only supposed eyewitness testimony came from inmate

informants.

As one might expect, there were credibility issues with all these witnesses.

The most common being that they were – in many cases – promised favorable

treatment for testifying. The prosecutor agreed to drop an assault charge for

Anthony Casey in exchange for his testimony. Trial Tr. vol. 42: 69. Harold

Mitchell was told that prosecutors would write a favorable letter to the parole

board for him if he testified. Id. at 246. The same promise was made to Michael

5

this Court, Pruett v. State, No. AP-77,037, and are abbreviated as Clerk’s R. vol. [number]: [page
number].

10
Wayne Hall and Ross Alexander Kirkpatrick. Trial Tr. vol. 43: 36-37; 45: 169.

Furthermore, there is reason to believe that these favorable letters were effective,

as some of the witnesses – incarcerated at the time of Nagle’s murder – had been

paroled before Pruett’s trial even began. Trial Tr. vol. 42: 22, 116-17.

Although the foregoing deals were revealed to defense counsel by the State,

habeas counsel has subsequently discovered that the inmates who testified for the

State received special treatment far beyond what was disclosed at trial. Notes from

the SPU indicate that Harold Mitchell, for example, wanted to be transferred to

another state in exchange for his testimony. Clerk’s R. vol. 1: 60. According to

Gary Jackson, who was at the McConnell Unit, Mitchell confirmed that he was in

fact offered an interstate compact to testify. Id. at 62. This important detail was

not revealed at Pruett’s trial.

Moreover, many of the inmates who ultimately testified against Pruett

initially claimed to have no knowledge of the crime or insisted that Pruett had

nothing to do with the murder; they changed their stories over the course of the

next year, only after being promised favors or something of value by the

prosecution. See, e.g., Trial Tr. vol. 42: 182, 259-60.

In addition, the testimony of the various inmates was internally inconsistent.

Indeed, the testimony was so noticeably inconsistent that the State made excuses

for it in closing argument. Trial Tr. vol. 46: 15 (“And in this case we knew before

11
we brought you these inmates that the peripheral things, which way did he arrive,

what kind of clothing was he wearing, did he keep his shirt on or not, we knew that

was going to be a jumble.”).

In contrast to the favorable treatment shown to the inmates who testified for

the State, the inmates who testified on behalf of Mr. Pruett – rather than receiving

favorable treatment – were threatened by correctional officers. Trial Tr. vol. 44:

92. For example, fear of retaliation from correctional officers kept James Richard

from telling investigators that he knew that Pruett had cut his hand before Nagle

died instead of – as the State alleged at trial – in the act of killing Nagle. Clerk’s

R. vol. 1: 65-66.

Both sides rested on April 19, 2002. Trial Tr. vol. 45: 232. The jury began

deliberating immediately after lunch on Monday, April 22, 2002. Trial Tr. vol. 46:

79-80. The fact that the jury considered the state’s case weak is evident from the

fact that jurors spent an entire day deliberating guilt/innocence. The jury

deliberated until after lunch the following day. Trial Tr. vol. 47: 16-17. Pruett was

found guilty on April 23 and was sentenced to death on April 30. Trial Tr. vol. 47:

17; 51: 57.

D. Chapter 64 proceedings

On May 9, 2013, Pruett filed a Motion for Post-Conviction DNA and Palm

Print Testing. Clerk’s R. vol. 1: 2. Believing the presence of a palm print on the

12
report indicated there were likely sufficient epithelial cells on the report that a

DNA profile could be developed through processes unavailable at the time of his

trial, Pruett asked the trial court to order that the pieces of the disciplinary report be

tested. Clerk’s R. vol. 1: 14. Pruett further requested that the palm print on the

report be compared to the palm print database maintained by the Department of

Public Safety (DPS). Clerk’s R. vol. 1: 15.

On June 6, DPS reported that it was unable to match the palm print on the

report with any of the prints maintained in its database. Id. at 42. The State then

sent the evidence to the University of North Texas Center for Human Identification

(UNTCHI) for collection and analysis of DNA. UNTCHI subsequently issued a

report (on July 9, 2013) indicating that its testing had been inconclusive.

After the trial court ordered the lab to provide Pruett’s habeas counsel with a

copy of the case file generated during testing, counsel observed what appeared to

be markers at several loci. However, UNTCHI had made no attempt to determine

whether Pruett and Nagle could be excluded as being contributors to the sample,

despite the court order to do so. Clerk’s R. vol. 1: 36, 81.

Habeas counsel subsequently filed a motion asking the court to appoint

Charity Holland of Mitotyping Technologies to assist counsel in preparing for the

hearing that had been set for November 18. Id. at 47-56. On November 18, 2013,

the Court appointed Ms. Holland to assist counsel.

13
 Ms. Holland’s review revealed that of the several loci at which counsel had

observed markers while reviewing UNTCHI’s file, markers were only present in

an amount above the analytical threshold at one locus. Rep.’s R. vol. 2: 3.6 The 12

allele was identified as being present at the D13 locus. Id. While the UNTCHI’s

conclusion that the results were inconclusive was correct because it would be

inappropriate to report a match with a known person based on such an incomplete

profile, it was possible to determine whether individuals could be excluded as

being the source of the DNA. Because the DNA profiles of both Nagle and Pruett

contain the 12 allele at the D13 locus, id., neither could be eliminated as being a

possible source of the DNA left on the disciplinary report. This 12 allele is present

at the D13 locus in the DNA profiles of “approximately 20% of the Asian and

Hispanic populations, 30% of the Caucasian population, and 40% of the African

American population.” Rep.’s R. vol. 2: 4. In other words, approximately one-

third of the population at the McConnell Unit could not be excluded as

contributing the DNA still present on the report.

The trial court concluded, in view of the inconclusive DNA results, that the

evidence was not exculpatory, and this Court affirmed. According to the Court,

v. State, No. AP-77,037, 2014 WL 5422573, at *2 (Tex. Crim. App. Oct. 22,

2014).

ARGUMENT AND AUTHORITY

In 2001, the State of Texas gave death-sentenced individuals the right to

have potentially exculpatory biological evidence tested. Tex. Code Crim. Proc. ch.

64 (attached as Exhibit E). In addition, a different provision of Texas law

mandates that, in cases where a defendant is convicted of a capital felony, all

biological evidence collected during the State’s investigation be preserved “until

the inmate is executed, dies, or is released on parole….” Tex. Code Crim. Proc. art.

38.43(c)(2)(A) (attached as Exhibit F). The Texas Department of Public Safety has

issued a handbook that explains what is required for biological evidence to be

properly preserved.

In this case, the State collected and possessed evidence that could have

conclusively established Mr. Pruett’s innocence, and aided in the identification of

the actual perpetrator(s). But by engaging in lengthy delay before testing the

evidence, and by storing it in a grossly negligent manner, the State has deprived

Mr. Pruett of the possibility of proving his innocence. It now threatens him with

imminent execution when his inability to establish his innocence is due to the

State’s very conduct.

15
I. State statutes and guidelines mandated that the physical evidence be
preserved properly until Mr. Pruett was either executed, died, or was
released on parole.

The Texas Code of Criminal Procedure defines “biological material” as “an

item that is in possession of the state and that contains blood, semen, hair, saliva,

skin tissue or cells, fingernail clippings, bone, bodily fluids, or other identifiable

biological evidence that may be suitable for forensic DNA testing.” Tex. Code

Crim. Proc. art. 64.01(1). The apparently synonymous term “biological evidence”

is defined similarly in the preservation statute. Tex. Code Crim. Proc. art.

38.43(2). Because they were collected by the State in the course of investigating

Officer Nagle’s murder, and because they contain skin tissue and blood and might

reasonably (had they been properly preserved) be used to either identify the person

that murdered Officer Nagle or exclude a person from the group of persons that

could have murdered Officer Nagle, the torn pieces of the disciplinary report

satisfy the statutory definitions of “biological material” and “biological evidence.”

Consequently, the material Mr. Pruett sought to test – the material that could have

demonstrated his innocence – was required by state law to have been collected and

preserved.

Various arms of the State were involved in the collection, storage, and

analysis of the evidence; all of them are subject to the requirements of article 38.43

– that is, the statute’s obligations apply to the investigators that collected the

16
evidence, the DPS crime lab analysts, the SPU, and (presumably) the Bee County

Clerk’s office, see supra note 4. Tex. Code Crim. Proc. art. 38.43(b).

Accordingly, each of these entities was charged with properly preserving the

pieces of the disciplinary report until Mr. Pruett was executed, died, or was

released on parole. Id. art. 38.43(c)(2)(A).

The DPS published a document detailing the best practices for collecting,

packaging, storing, preserving, and retrieving biological evidence (attached as

Exhibit G). The section pertaining to “biological evidence” uses the definition of

that term found in article 38.43 and clearly anticipates items such as the torn pieces

of paper. Exhibit G at A-028, A-029 (listing paper towels and handled items as

potential sources of biological material). The handbook makes clear that when

packaging biological evidence, it is necessary to “avoid the use of plastic

packaging as an inner or outer package.” Exhibit G at A-030. The Physical

Evidence Handbook, also published by DPS (excerpt attached as Exhibit H),

emphasizes the point: “Do not use plastic packaging for biological evidence.”

Exhibit H at A-038. It is vital that biological evidence not be stored in plastic bags

because “they provide a growth medium for bacteria that may degrade DNA

evidence.” DNA Evidence: What Law Enforcement Officers Should Know, NIJ

Journal, July 2003, at 10, 13, available at

https://www.ncjrs.gov/pdffiles1/jr000249c.pdf; see also U.S. Dep’t of Commerce

17
Technical Working Group on Biological Evidence Preservation, The Biological

Evidence Preservation Handbook: Best Practices for Evidence Handlers 16 (2013),

available at http://www.crime-scene-investigator.net/BiologicalEvidence

PreservationHandbook.pdf.

As Exhibit D demonstrates, the pieces of paper were stored in plastic bags –

against the recommendations of the DPS – from at least February 24, 2000 until at

least July 1, 2013. It is impossible to know whether the torn pieces of the report

contained sufficient epithelial cells to produce a complete profile when they were

initially collected by Officer Chris King on December 17, 1999. What is known,

though, is that DNA was not present in a sufficient amount when it was analyzed

in July 2013 after being stored in a plastic bag for thirteen years. What is also

known is that the entities that had a duty to preserve the evidence failed to preserve

it in a way that would best preserve it.

Evidence such as the torn pieces of the disciplinary report are best preserved

in a temperature controlled environment in which temperature is maintained

between sixty and seventy-five degrees Fahrenheit with less than sixty percent

humidity. Biological Evidence Preservation Handbook, supra, at 17-18. While

counsel cannot be certain of the environment in which the evidence was stored

(presumably the Bee County Clerk’s office), it is unlikely that an effort was made

to control the environment as needed to best preserve the evidence.

18
II. Mr. Pruett had a state-created right to have the evidence tested.
Fundamental fairness as well as state statutory law required the
evidence be properly preserved. Because it was not, his execution would
violate the Eighth and the Fourteenth Amendments.

Pursuant to article 64.03 of the Code of Criminal Procedure, if a death-

sentenced man, such as Mr. Pruett, presents a motion that requests to have

biological material tested that still exists in a condition that makes testing possible

and could yield exculpatory results, he is entitled to have the evidence tested. Tex.

Code Crim. Proc. art. 64.03. While absent the state-created right, Mr. Pruett did

not have a right to have the evidence tested, because the state gave him that right, it

must also ensure that the processes it employs as he avails himself of the right due

not violate fundamental fairness. See Dist. Attorney’s Office for Third Judicial

Dist. v. Osborne, 557 U.S. 52, 69 (2009).

In Mr. Pruett’s case, however, the State – by failing to properly preserve the

evidence he was entitled to have tested – has violated the principles of fundamental

fairness. Even if the Eighth Amendment does not create a right that permits an

inmate to establish his innocence in post-conviction proceedings, both Congress in

enacting AEDPA and the State of Texas in enacting Chapter 64 have demonstrated

the offensiveness of carrying out the execution of someone who is actually

innocent. Before either AEDPA or Chapter 64 were enacted, this Court recognized

that the “execution of an innocent person would violate the Due Process Clause of

19
the Fourteenth Amendment.” Ex parte Elizondo, 947 S.W.2d 202, 204 (Tex Crim.

App. 1996) (citing State ex. rel. Holmes v. Court of Appeals, 885 S.W.2d 389, 397

(Tex. Crim. App. 1994)). In Mr. Pruett’s case, however, the State purported to

allow him (and others like him) to prove their innocence, but then made the

demonstration impossible by negligently handling the evidence. Both the Due

Process Clause and the Eighth Amendment’s concern with reliable determinations

of guilt will be offended by permitting the execution of Mr. Pruett to go forward.

III. Mr. Pruett is clearly entitled to the relief sought and has no other
remedy at law.

Extraordinary relief – such as a writ of prohibition – is available only where

the Relator is clearly entitled to relief and where there is no other adequate remedy

to protect Relator’s rights or interests. Curry v. Wilson, 853 S.W.2d 40, 43 (Tex.

Crim. App. 1993). Because Pruett “has no right to present his Eighth Amendment

claim by way of appeal or habeas corpus application under Article 11.071,” the

Court should find he has no adequate remedy at law. Chi, 256 S.W.3d at 702.

The Court should similarly find Pruett is entitled to the relief sought. Prior

to Pruett’s trial, the legislature enacted a means by which defendants are allowed to

attempt to establish they are innocent of the crimes they were committed. To allow

the State to circumvent the intent of the legislature by failing to properly preserve

evidence would be an injustice. This is particularly true in the case of death-

20
sentenced inmates, such as Pruett. This is not a case where the evidence in

question was tangential and of the sort that the State had no reason to believe it

necessary to properly preserve. The evidence at issue – the torn pieces of the

disciplinary report – was the State’s case.

PRAYER FOR RELIEF

Accordingly, Relator Pruett respectfully requests that this Court issue and

order prohibiting the Director from carrying out Pruett’s execution on April 28,

2015 because his execution would be in violation of the Eighth and Fourteenth

Amendments to the United States Constitution.

Respectfully Submitted,

pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned. But neither the United States
nor any State shall assume or pay any debt or obligation incurred in aid of insurrection or rebellion against the United States,
or any claim for the loss or emancipation of any slave; but all such debts, obligations and claims shall be held illegal and void.

(d) The attorney representing the state, clerk, or other officer in
possession of biological evidence described by Subsection (a) may destroy
the evidence, but only if the attorney, clerk, or officer by mail
notifies the defendant, the last attorney of record for the defendant,
and the convicting court of the decision to destroy the evidence and a
written objection is not received by the attorney, clerk, or officer from
the defendant, attorney of record, or court before the 91st day after the
later of the following dates:
(1) the date on which the attorney representing the state,
clerk, or other officer receives proof that the defendant received notice
of the planned destruction of evidence; or
(2) the date on which notice of the planned destruction of
evidence is mailed to the last attorney of record for the defendant.
(e) To the extent of any conflict, this article controls over
Article 2.21.
(f) The Department of Public Safety shall adopt standards and rules
authorizing a county with a population less than 100,000 to ensure the
preservation of biological evidence by promptly delivering the evidence

to the Department of Public Safety for storage in accordance with Section
411.053, Government Code, and department rules.
(g) The Department of Public Safety shall adopt standards and
rules, consistent with best practices, relating to a person described by
Subsection (b), that specify the manner of collection, storage,
preservation, and retrieval of biological evidence.
(h) A person described by Subsection (b) may solicit and accept
gifts, grants, donations, and contributions to support the collection,
storage, preservation, retrieval, and destruction of biological evidence.
(i) Before a defendant is tried for a capital offense in which the
state is seeking the death penalty, subject to Subsection (j), the state
shall require either the Department of Public Safety through one of its
laboratories or a laboratory accredited under Section 411.0205,
Government Code, to perform DNA testing, in accordance with the
laboratory's capabilities at the time the testing is performed, on any
biological evidence that was collected as part of an investigation of the
offense and is in the possession of the state. The laboratory that
performs the DNA testing shall pay for all DNA testing performed in
accordance with this subsection.
(j) As soon as practicable after the defendant is charged with a
capital offense, or on a motion by the state or the defendant in a
capital case, unless the state has affirmatively waived the death penalty
in writing, the court shall order the state and the defendant to meet and
confer about which biological materials collected as part of an
investigation of the offense qualify as biological evidence that is
required to be tested under Subsection (i). If the state and the
defendant agree on which biological materials constitute biological
evidence, the biological evidence shall be tested in accordance with
Subsection (i). If the state and the defendant do not agree on which
biological materials qualify as biological evidence, the state or the
defendant may request the court to hold a hearing to determine the issue.
On receipt of a request for a hearing under this subsection, the court
shall set a date for the hearing and provide written notice of the
hearing date to the state and the defendant. At the hearing, there is a
rebuttable presumption that the biological material that the defendant

A-024
CODE OF CRIMINAL PROCEDURE CHAPTER 38. EVIDENCE IN CRIMINAL ACTIONS 1/20/15, 3:07 AM

requests to be tested constitutes biological evidence that is required to
be tested under Subsection (i). This subsection does not in any way
prohibit the state from testing biological evidence in the state's
possession.
(k) If an item of biological evidence is destroyed or lost as a
result of DNA testing performed under Subsection (i), the laboratory that
tested the evidence must provide to the defendant any bench notes
prepared by the laboratory that are related to the testing of the
evidence and the results of that testing.
(l) The defendant's exclusive remedy for testing that was not
performed as required under Subsection (i) or (j) is to seek a writ of
mandamus from the court of criminal appeals at any time on or before the
date an application for a writ of habeas corpus is due to be filed in the
defendant's case under Section 4(a), Article 11.071. An application for
a writ of mandamus under this subsection does not toll any period of
limitations applicable to a habeas petition under state or federal law.
The defendant is entitled to only one application for a writ of mandamus
under this subsection. At any time after the date an application for a
writ of habeas corpus is filed in the defendant's case under Section
4(a), Article 11.071, the defendant may file one additional motion for
forensic testing under Chapter 64.
(m) A defendant may have another laboratory accredited under
Section 411.0205, Government Code, perform additional testing of any
biological evidence required to be tested under Subsection (i). On an ex
parte showing of good cause to the court, a defendant may have a
laboratory accredited under Section 411.0205, Government Code, perform
testing of any biological material that is not required to be tested
under Subsection (i). The defendant is responsible for the cost of any
testing performed under this subsection.

BEST PRACTICES FOR COLLECTION, PACKAGING, STORAGE,
PRESERVATION, AND RETRIEVAL OF BIOLOGICAL EVIDENCE
Definitions of Biological Evidence and Biological Material

“Biological evidence” is defined in Art. 38.43 Code of Criminal Procedure, as follows:
1. The contents of a sexual assault examination kit; or
2. Any item that contains blood, semen, hair, saliva, skin tissue, fingernail scrapings, bone,
bodily fluids, or any other identifiable biological material that was collected as part of an
investigation of an alleged felony offense or conduct constituting a felony offense that
might reasonably be used to:
a) Establish the identity of the person committing the offense or engaging in the
conduct constituting the offense; or
b) Exclude a person from the group of persons who could have committed the offense
or engaged in the conduct constituting the offense.
Items to Consider as Sources of Biological Evidence or Materials for the Purpose of
this Statute
The following list is meant only as a general guide for use in the investigation of crimes in
which biological evidence and materials may have evidentiary value. These are:
• Sexual assault examination kits, both victim and suspect kits
• Slides, swabs, test tubes or the proximate container for each from sexual assault
examination kits and autopsies
• Clothing, hats, masks, eyeglasses, jewelry, gloves from any involved individuals
• Ligatures such as rope, belts, tape and cords
• Bedding such as sheets, blankets, comforters, pillow cases, pillows and mattress
pads
• Other household materials such as towels, used tissues, toilet paper and paper
towels
• Condoms
• Drinking containers such as cups, cans and bottles
• Cigarette butts or other smoking devices
• Handled items such as weapons and tools
• Licked items such as envelopes and stamps
• Samples of items retained by a coroner for forensic or toxicology laboratory testing
• Biological reference standards from known individuals such as buccal swabs from a
victim, suspect, consensual sex partner or elimination standards
• Secondary reference standards from missing persons such as a toothbrush or hair
brush
The above list is not exhaustive. There are many other possible sources of biological
evidence or materials.

locations of possible biological material.
Items Which Should Not Be Considered As Biological Evidence for the Purpose of
this Statute
• Sample of whole blood from a DWI suspect

Evidence Collection

Biological evidence and materials should be collected in a manner that prevents
contamination and degradation and ensures integrity during all phases of the investigation
and litigation. To avoid contamination, sample collection tools and materials must be free
from human DNA. Disposable latex examination gloves, individually wrapped swabs or other
individually wrapped items are free of human DNA by virtue of the process of manufacture.
Not all germicidal treatments destroy DNA. Alcohol and hydrogen peroxide, for instance, do
not destroy DNA. The most effective way to clean collection equipment is to wipe it with a
fresh 10% bleach solution of 10:1 water to bleach. (Any commercially available bleach is
adequate for this purpose.)
Clean Collection Practices
Here are examples of ways to prevent contamination and degradation of biological
evidence:
1. Use disposable latex (or similar) gloves to handle evidence rather than reusable
uniform/tactical gloves. Do not touch the outside of gloves to face or hands, or
use personal items such as cell phones or radios and change gloves after
contact with potential biological evidence.
2. When field testing evidence, swab the stain and test the swab rather than directly
testing the stain. If the stain is small, it should be tested in a lab rather than in the
field.
3. Fingerprint powder and brushes carry biological material from one item to the
next. Collect DNA samples before powdering or use single use brushes and
sterile powder.
4. Clean tools between samples. For example, dip forceps in a fresh 10% bleach
solution of 10:1 water to bleach and thoroughly dry prior to reuse.
5. When it is necessary to dampen a swab to collect a dried stain, any source of
water that does not contain human DNA is acceptable. Sterile water, distilled
water, saline solution and tap water meet this definition. Document which type of
water is used.
6. Dry damp items and swabs. When it is not possible to thoroughly dry the item,
packaging such as paper bags will allow the drying process to continue.
7. Wet items may be dried by hanging or by laying out on a clean surface indoors
away from the scene.
8. Package each item separately.
9. The use of personal protective equipment (disposable clothing, gloves, masks,
etc.) both protects the individual from biohazard exposure and prevents transfer
of the investigator’s DNA to the evidence.

Effective Date: 10/30/2012 A-029
Best Practice LAB-BP-01
Version: 00
Collection, Packaging, Storage, Preservation, and Retrieval of Biological Evidence Page 3 of 8
To implement these provisions, these tools are useful:
• Latex or similar gloves
• Sterile swabs
• Water
• Paper containers such as bags, envelopes, boxes
• Tamper Evident Tape
• Permanent marker
Packaging
These are best practices to keep in mind when packaging biological evidence at a crime
scene:
• Package evidence and seal the container to protect it from loss, cross transfer,
contamination and/or deleterious change.
• Seal the package in such a manner that opening it causes obvious damage or
alteration to the container or its seal.
• Package evidence for safety by using boxes or breathable tubes for sharp items,
marking items and informing the laboratory if a biohazard is present.
• Package unloaded firearms in clean, unused boxes when submitting them for
biological analysis. Mark the packaging and inform the laboratory if a biohazard is
present.
• Use paper bags, envelopes, boxes and similar materials for all biological evidence.
• Avoid plastic packaging as an inner or outer package.
• Avoid the use of pill tins due to possible rust.
• Ensure that all swabs and evidence are dry.
• Package each item separately; avoid commingling items to prevent cross
contamination.
• Swabs collected from a single item may be packaged in the same container.
• Mark each package with a detailed description that includes the item, location where
it was collected, name of the person who collected it and date of collection.
• Seal each package with tape. (staples are not considered a proper seal.) All seals
must be marked to identify the person making the seal. Mark through the seal with
name or initials and date.
• The integrity of the item often is maintained through the package’s documentation.
That documentation includes all markings, seals, tags and labels used by all of the
involved agencies. Therefore, it is critical to preserve or document all packaging and
labels received by or returned to your agency.
Note: If an item (such as a used condom or fetus/product of conception) cannot be dried, it
may be placed in plastic and frozen. The laboratory should be contacted as soon as
possible for further guidance.

Best Practice LAB-BP-01
Version: 00
Collection, Packaging, Storage, Preservation, and Retrieval of Biological Evidence Page 4 of 8
Document Evidence
During the collection process, it is essential to record the location of evidence collected at a
crime scene. These are effective methods to do this:
• Use photographs and placards to document the location of each item.
• Develop detailed documentation that describes the item, location where it was
collected, name of the person who collected it and date of collection.
• Make a sketch of the scene that includes distances and a legend.
Contamination Prevention
To limit the potential for outside contamination of evidence prior to and during the collection
process:
• Secure and limit the scene to essential personnel.
• Change disposable gloves if there is contact with biological material.
• Avoid glove-to-skin contact that can occur by rubbing eyes or nose or wiping
perspiration.
• Avoid talking, coughing, sneezing, perspiring on or over evidence.
• Avoid walking on or over evidence.
• Avoid hair loss at scene from head, arms or face.
• Leave the scene if you become injured. Do not return until any blood loss has been
stopped and clothing is clean.
• Do not eat, drink, chew gum or use tobacco at a scene.
• Consider the use of disposable personal protective equipment (PPE) such as gloves,
masks, shoe covers, coveralls and hair covers when appropriate.
• Avoid skin and oral contact with investigatory tools such as measuring tapes or pens
that may have contacted contaminated surfaces.
• Do not discard any trash in or near the crime scene such as cigarette butts, used
disposable gloves, cups, or bottles.
• Take care when using cell phones/radios or other personal items. Make sure not to
use them when you have gloves on to avoid contamination.

Storage of Biological Evidence (Short-Term)

The storage of biological evidence in this section pertains to the short-term storage that is
necessary during all phases of investigation and litigation.
Biological evidence that has been dried should be stored in a facility that minimizes extreme
heat and humidity, which can cause DNA to degrade.
Items that are dried and extremely odorous may be retained in a sealed plastic bag.
Biological evidence that cannot feasibly be dried should be stored frozen. However, items
returned to the law enforcement governmental evidence-retention entity after laboratory
analysis that are no longer frozen may be stored as dry material in a designated property
room with little fluctuation in temperature and humidity. Whole blood should be spotted onto

Effective Date: 10/30/2012 A-031
Best Practice LAB-BP-01
Version: 00
Collection, Packaging, Storage, Preservation, and Retrieval of Biological Evidence Page 5 of 8
sterile cloth, bloodstain card paper, or FTA paper by laboratory personnel for storage at
room temperature.
All packages should be stored in a sealed condition that does not allow for cross
contamination, loss or deleterious change. All seals must be marked to identify the person
making the seal.
Packages from the same case should be stored in the fewest number of containers using
boxes or large bags, with care taken to avoid contamination of evidence. For both storage
and retention, boxes provide the most efficient use of space.
Note that some items of evidence containing biological evidence may be too large to
reasonably store, especially for long periods of time. For items such as vehicles, mattresses,
and other large items, it may be appropriate to photograph the item, clearly showing the
location of the biological evidence, and then cut and remove the portion containing the
biological material for testing and storage.

Retention of Biological Evidence (Long-Term)

Retention of biological evidence and/or material pertains to long-term storage of evidence
from inactive cases, cold cases or after litigation.
Long-term evidence retention should be part of the governmental evidence-retention entity’s
evidence control policy.
Whenever possible, all evidence from a case should be retained by one governmental
evidence-retention entity.
All packages should be stored in a sealed condition that does not allow for cross
contamination, loss or deleterious change. All seals must be marked to identify the person
making the seal.
Packages from the same case should be stored in the fewest number of containers
possible, such as boxes or large bags needed for that case, with care taken to avoid
contamination of evidence. For storage and retention, boxes provide the most efficient use
of space.
Items that are dried and extremely odorous may be retained in a sealed plastic bag.
Agency case numbers and identifiers must never be removed by another agency unless
documented.
A container such as a box or bag containing multiple items or packages must only be used
to store evidence from a single case and should be marked to reflect the contents of that
container.
Any governmental evidence-retention entity retaining biological evidence must be able to
produce an inventory of the evidence. It is best to maintain an evidence inventory in a
computer management system that can be backed up. In the absence of such a system, an
inventory based on chain-of-custody records must be maintained. It must list the item and its
current location as well as document receipt and transfer of the evidence. It is
recommended that the original investigating agency maintain the inventory for each case.
Governmental entities in counties with a population under 100,000 may deliver biological
evidence to the Texas Department of Public Safety for storage. The address, phone
number, and e-mail address of the DPS storage site will be posted on the DPS website at
www.dps.texas.gov. Search the site under the heading of bio-evidence storage. Note that
DPS storage is intended to be long term retention of the evidence. This would apply both to
evidence after a person is convicted, and to evidence in a cold felony case. Agencies are

Effective Date: 10/30/2012 A-032
Best Practice LAB-BP-01
Version: 00
Collection, Packaging, Storage, Preservation, and Retrieval of Biological Evidence Page 6 of 8
advised to store biological evidence locally until cases are adjudicated, so that the evidence
is available for the pending trial.

Biological Evidence Retention & Preservation Timeline

The retention and preservation schedule for biological evidence is described in Art.38.43 (c)
Code of Criminal Procedure.
b) This article applies to a governmental or public entity or an individual, including a law
enforcement agency, prosecutor’s office, court, public hospital, or crime laboratory, that
is charged with the collection, storage, preservation, analysis, or retrieval of biological
evidence.
c) An entity or individual described by Sub-section (b) shall ensure that biological evidence
collected pursuant to an investigation or prosecution of a felony offense or conduct
constituting a felony offense is retained and preserved.
It is important to note that the following retention schedules apply to both adult
offenders of felony offenses and to juvenile offenders of conduct constituting a
felony.
The retention schedules for biological evidence and materials are provided below.
1. Unsolved: for not less than 40 years, or until the applicable statute of limitations
has expired, if there is an un-apprehended actor associated with the offense.
2. Convictions: In a case in which a defendant has been convicted placed on
deferred adjudication community supervision, or adjudicated as having engaged
in delinquent conduct and there are no additional un-apprehended actors
associated with the offense:
a) until the inmate is executed, dies, or is released on parole, if the defendant
is convicted of a capital felony.
b) until the defendant dies, completes the defendant's sentence, or is
released on parole or mandatory supervision, if the defendant is sentenced
to a term of confinement or imprisonment in the Texas Department of
Criminal Justice.
Destruction of Biological Evidence
Art. 38.43 (d), Code of Criminal Procedure contains the provisions for destruction of
biological evidence in cases resulting in the conviction of a person for a felony offense, as
follows:
c) The attorney representing the state, clerk, or other officer in possession of biological
evidence described by Subsection (a) may destroy the evidence, but only if the attorney,
clerk, or officer by mail notifies the defendant, the last attorney of record for the
defendant, and the convicting court of the decision to destroy the evidence and a written
objection is not received by the attorney, clerk, or officer from the defendant, attorney of
record, or court before the 91st day after the later of the following dates:
1. The date on which the attorney representing the state, clerk, or other officer receives
proof that the defendant received notice of the planned destruction of evidence; or
2. The date on which notice of the planned destruction of evidence is mailed to the last
attorney of record for the defendant.
See Appendix A for the format of a Notice of Intent to Destroy Biological Evidence.

Effective Date: 10/30/2012 A-033
Best Practice LAB-BP-01
Version: 00
Collection, Packaging, Storage, Preservation, and Retrieval of Biological Evidence Page 7 of 8

To augment the available storage space for retained biological or other evidence required by
statute, it is recommended that each governmental evidence-retention entity routinely
inventory its property room for evidence that could possibly be destroyed. Crimes that
require adherence to these biological evidence retention standards are felony crimes.
When evidence is being held for cases on appeal, consult the prosecuting attorney for an
updated status and the possibility of seeking a destruction order.
Questions in reference to cases that are open or unsolved should be referred to the
prosecuting attorney to determine the statute of limitations and the possibility of future
litigation or the possibility of seeking a destruction order.
Cataloging of Retained Evidence
A governmental evidence-retention entity must have a system to catalog evidence so it is
possible to locate any retained biological evidence.
A cataloging system should make use of a unique case numbering system, a documented
procedure for property room organization and the evidence inventory developed for each
case.
Evidence control should include a case numbering system. The case numbering system
should include unique case identifiers with unique property identifiers.
The organization of the property room should be determined by the governmental evidence-
retention entity’s ability to locate the evidence through a computerized barcode system or
hand written record.

Biological Screening/DNA Evidence

INTRODUCTION

Eight of the DPS Crime Laboratories provide biological case screening for the presence of
blood and/or body fluids and STR (short tandem repeat) nuclear-based DNA testing on
evidence from criminal investigations. Examinations performed will be based on the type of
case submitted and the quality and quantity of forensic samples detected.
Biological evidence may be submitted to the Regional Crime Laboratories in Austin
Headquarters, Corpus Christi, El Paso, Garland, Houston, Lubbock, Weslaco, and Waco.
Successful DNA results are dependent on the amount and condition of the evidentiary
material. Factors such as extreme or environmental conditions to which the material has
been exposed, substrate on which the material is found, and the exposure of the sample
area to multiple individuals may affect DNA results and should be considered prior to
submitting evidence for processing. For example, it is highly unlikely to obtain a DNA profile
from the individual who originally loaded fired ammunition components (bullets or cartridge
cases).
The following determinations may be requested when submitting evidence for
biological screening/DNA examinations:
• Presence of biological material (e.g. blood, semen, or other DNA-yielding
stains)
• Presence of human DNA
• Comparison of DNA profiles obtained from questioned or crime scene samples
to DNA profiles from known or reference samples.
• Preservation of trace evidence
A laboratory report will be issued explaining results of analysis and relevant conclusions.
For a DNA report, the laboratory will summarize the results of comparisons of DNA profiles
which may include the significance of associations with known references.
Additionally, a DNA profile may be entered into the Combined DNA Index System (CODIS)
database that contains DNA profiles from known individuals and forensic case samples.
Profiles can be searched against other profiles for the purpose of helping to generate
investigative leads.
Please note that the submission of elimination samples, such as reference samples
from a consensual partner in the case of a sexual assault, is requested prior to the
entry of crime scene samples into CODIS. These standards should be collected
during the initial investigation, packaged separately from the evidence, and should be
submitted at the same time as the evidence if possible in order to facilitate timely
laboratory response.

SAFETY CONSIDERATIONS

At a minimum, latex, nitrile, or other non-porous polymer gloves must be worn when
recovering and packaging biological evidence. Additional personal protective equipment
such as eye protection, face masks, head/hair covering, and lab coats may be beneficial for
personal safety and to avoid contamination of the evidence.

Version 02
Biological Screening/DNA Evidence

All biological stains and reference samples should be treated as a biohazard (Universal
Bloodborne Pathogen Precautions). These samples could potentially expose the handler to
HIV, Hepatitis B and C, or other pathogens.
If blood samples are shipped such that they would be traveling by air, they must be
packaged by IATA (International Air Transport Association) regulations.

COLLECTION

The use of proper collection and evidence handling procedures reduces the possibility of
evidence contamination and DNA degradation. Therefore, observe the following guidelines:
• Do not package known reference samples in the same packaging as questioned
samples.
• Package individual items of clothing from the same person in separate containers.
• If the exact location of evidentiary DNA on an item is important, wrap the item in
clean white paper and roll it up on itself prior to placing in a bag in order to prevent
transfer of evidence from one location on the item to another location.
• Do not package evidence collected from one individual with evidence collected from
a second individual.
• Do not package crime scene evidence with evidence collected from an individual.
• Wear gloves and change frequently, or when they become soiled.
• Avoid talking, coughing, or sneezing over the unpackaged evidence.
Collection of Evidentiary Samples
Observe the following steps to collect evidence samples:
• Document and photograph the removal of stains.
• Use sterile swabs to absorb wet stains from non-absorptive surfaces.
• Cut out questioned stains from large items such as car seats and bedding.
• Dampen a sterile swab, using sterile water, to collect dry stains from walls or other
larger items. Do not scrape dried stains. They can flake into dust and become
static, making the particles difficult to handle.
• IMPORTANT: Air dry any wet items or swabs before packaging and sealing. If items
cannot be dried prior to submission, the laboratory must be consulted.
• The collection of control swabs from the scene is not required. If submitted, these
samples will not be processed through DNA analysis.
Collection of Known Reference Samples
• Collect blood standards in purple top blood tubes labeled with the individual’s name.
Purple top blood tubes contain a chemical preservative, EDTA. Verify that the
collection is prior to the expiration date on the tube.
• Collect buccal samples (swabbings of the inner cheeks of the mouth) onto at least
two sterile cotton swabs and air dry prior to packaging. Buccal swabs from one
individual do not need to be labeled as to the side from which they were collected
and may be packaged together. To avoid possible contamination, allow the

individual to collect the sample him/herself in the presence of a witness. The
packaging should list the individual’s name.
• Information of suspected blood transfusions of the victim and/or suspect should be
provided to the laboratory.

PRESERVATION AND PACKAGING

Questioned stains and known reference samples naturally degrade. However, the
degradation process may by be slowed by proper collection and preservation:
• Thoroughly dry the wet or moist items, such as clothing or swabs, before
packaging.
• Refrigerate liquid biological samples until submission to the laboratory.
• Freeze tissue samples until transporting to the laboratory for submission.
• Package items in white paper. Do not use plastic packaging for biological evidence.
• Store the packaged items in a cool, dry area. Avoid sunlight, heat, and excessive
humidity.
• Refrigerate sexual assault kits if they contain liquid samples, such as blood, until
submitted to the laboratory. If uncertain, the kits should be refrigerated. Do not
freeze the kits. Do not store the kit in hot conditions, such as the trunk of a car. The
heat may cause any blood tubes within the kit to explode.
• Label and seal all packaging properly. IMPORTANT: Mark all packages with
biological hazard stickers.

Biohazard Warning Label
• Contact your local laboratory for specific instructions on collection,
packaging, and submission procedures.

SUBMISSION OF BIOLOGICAL EVIDENCE

When submitting evidence to a DPS Crime Laboratory, please follow the DNA case and
evidence acceptance policy - Criteria for DNA Evidence Submission, PEH-02-04A.
Generally, for bulky items such as bedding, mattresses, car seats, etc., please contact the
laboratory prior to submission to determine relative importance, facilitate processing, and
reduce storage space requirements.
Submit applicable supporting documentation:
• Offense reports and witness statements with the evidence
• Autopsy reports or medical records from the victim, when available and where
applicable.
• Photographs and sketches of the crime scene, as necessary.

to receive these items from the submitting agency.
Submission of Evidence from Sexual Assaults
In the state of Texas, licensed physicians and Sexual Assault Nurse Examiners (SANE
nurses) are authorized to collect samples from sexual assault victims.
Typical sexual assault kits may include the following:
• Orifice swabs (vaginal/oral/rectal) from victim (generally four per orifice) air dried at
room temperature. Each orifice swab collection should be performed with multiple
swabs simultaneously, unless conditions warrant otherwise. If the swabs are not
collected simultaneously, they should be marked as to the order of collection.
• Vaginal, oral, or anal smears from victim
• Penile swabs from victim (if the victim is male). This consists of rubbing the outside
of the penis with the swabs and is not the same method as collection of swabs for
testing for STDs.
• Blood specimen from victim (one purple top [EDTA] tube or a one inch spot on FTA
paper)
• Buccal specimen from victim (two swabs) air dried at room temperature
• Swabbings of areas of the victim’s body which were either licked or bitten by the
suspect during the assault (note location and supply the reasoning for their
collection).
• Pubic hair combings from victim (note reason if not collected)
• Head hair combings from victim (note reason if not collected)
• Pulled pubic hair standard from victim (note reason if not collected)
• Pulled head hair standard from victim (note reason if not collected)
• Fingernail clippings from victim
• Undergarments from victim (especially panties immediately worn after the assault)
Other evidence may include:
• Blood specimen from suspect (one purple top [EDTA] tube or a one inch spot on
FTA paper; or alternatively at least four buccal swabs may be collected from the
suspect)
• Buccal sample from suspect (four swabs) air dried at room temperature
• Penile swabs from suspect (only if apprehended a short time after the assault
occurred)
• Pubic hair combings from suspect (only if apprehended a short time after assault has
occurred)
• Pulled pubic hair from suspect
• Pulled head hair from suspect, when applicable
• Clothing from suspect, when applicable

Biological Screening/DNA Evidence

• Fingernail clippings or swabs of the suspect’s fingers/hands, if victim was injured.
• Swabs of the suspect's fingers (only if apprehended a short time after assault has
occurred).
Additional samples that may be collected from the victim if it is suspected that the victim may
have been drugged: blood sample collected in a gray top tube and a urine specimen. These
samples should be packaged separately from the victim’s sexual assault kit and preferably
in the DPS sanctioned blood and urine collection kits respectively. If blood alcohol and/or
toxicological drug analysis is requested on the blood specimen within the kit, the request
must be noted on the submission form. See PEH-02-03 Toxicology and Blood Alcohol
Evidence for handling and submission information.
Include the information listed on the Sexual Assault Information Form (LAB-24) with the
submission of the sexual assault evidence.
Note: The Sexual Assault Information Form (LAB-24) is an aid for laboratory
personnel to interpret items of evidence submitted by police officers or medical
personnel. This may be completed or a similar form may be found in the Texas Evidence
Collection protocol published by the Office of Attorney General’s Sexual Assault Prevention
and Crisis Service Division. The following is a link to the protocol.
