HARRY EASTER
v.
STATE OF MARYLAND

Opinion by Graeff, J.
Filed: May 27, 2015
Harry Easter, appellant, was convicted by a jury in the Circuit Court for Prince
George’s County of three counts of manslaughter by vehicle, one count of causing a life
threatening injury while operating a motor vehicle under the influence of alcohol, driving
under the influence of alcohol, reckless driving, speeding, and other related offenses. The
court sentenced appellant to an aggregate term of thirty years’ incarceration.
On appeal, appellant presents the following questions for our review, which we have
rephrased slightly, as follows:
1. Did the circuit court err in permitting the State to introduce the results
of a blood alcohol test where the State failed to establish a proper chain
of custody between the blood obtained from appellant and the blood
tested to obtain those results?
2. Did the circuit court err in permitting the State’s expert to offer
testimony relating to the data acquired from the air bag control module
of appellant’s vehicle where the State failed to establish the accuracy
and validity of the methodology used to acquire that data?
For the reasons that follow, we shall affirm the judgment of the circuit court.
FACTUAL BACKGROUND
On June 5, 2011, appellant drove his sport utility vehicle (“SUV”), at a speed of
approximately 89 miles per hour, into the rear of another vehicle. Appellant struck the car
with such force that the two rear-seat occupants were ejected through the rear window of the
car and killed. The driver also was killed when the car struck a tree. The front seat
passenger survived, but he sustained a fractured back, a fractured pelvis, an ankle injury, a
concussion, and other serious and debilitating juries.
When the surviving front seat passenger got out of the vehicle to look for his wife and
the driver’s wife, he saw appellant standing there. He asked appellant for help, but appellant
just continued to stand there, offering no assistance. Appellant’s blood alcohol content was
.24 grams per 100 ml of blood, three times the legal limit to operate a vehicle.
We shall incorporate additional facts, relevant to each of the questions presented by
appellant, in our discussion.
DISCUSSION
I.
Admission of Results of the Blood Test
Appellant first contends that the circuit court “erred in allowing the State to offer
blood test results because the State failed to establish the chain of custody between the blood
taken from [appellant] and the blood tested to produce [the] test result.” The State disagrees,
asserting that “the trial court acted within its discretion in admitting the results of
[appellant’s] blood test.”
A.
Proceedings Below
Officer Thomas Crosby, a member of the Prince George’s County Police Department,
testified that, on June 5, 2011, he transported appellant from the scene of the accident to Fort
Washington Hospital Center. He observed a phlebotomist draw blood from appellant to
measure his blood alcohol level.
-2-
Corporal Stephen Fox supplied the hospital with a blood collection kit. He described
a blood collection kit as a sealed cardboard box containing vials for blood collection, a
preparatory product to clean the skin at the collection site, and security seals and integrity
seals. Once the blood is collected, the vials are secured with the seals and then repackaged
in the cardboard box, which is then sealed. The blood collection kit that he provided to the
hospital was “new, unopened, and it was still within its expiration time period.”
Corporal Fox observed the phlebotomist draw blood from appellant. After the blood
was in the vials from the blood collection kit, the phlebotomist sealed the vials with integrity
seals and signed the chain of custody form, which was admitted as State’s Exhibit #14. This
form contained the phlebotomist’s signature, appellant’s name, the time and date of arrest,
and the time, date, and location of the sample collection.
Corporal Fox then repackaged the vials into a secured container with foam packaging,
put the container into a bag, and then put the bag in the cardboard box. Corporal Fox took
the repackaged blood collection kit to the Special Operations Division offices, and he placed
the package into the mail to the Chemical Test for Alcohol Unit of the Maryland State Police
for analysis. Corporal Fox testified that the legal limit in Maryland to operate a motor
vehicle is .08 grams per 100 ml of blood.
Phlebotomist Seleshe Russom confirmed that he drew blood from appellant using a
blood collection kit supplied to him by the police. He verified his signature on the police
chain of custody form, which had been admitted as State’s Exhibit #14.
-3-
Wayne Shu, a forensic scientist with the Maryland State Police Crime Lab, performed
the blood alcohol content testing in this case. He identified State’s Exhibit #14 as “a copy
of the Form 34 that’s filled out and provided.” He stated, however, that “there seemed to be
a bottom part missing to this,” explaining that his copy of the “Form 34 on the bottom has
where [he] could input the results and get the control number,” and that the exhibit was “a
little different than [his] copy, but it’s similar.”
Mr. Shu described the blood analysis process, in relevant part, as follows:
The blood kit is hand delivered to the Maryland State Police Crime Lab, which
is then received by our receiving unit. At that time, it’s logged into our
system, which is our evidence tracking system. When I’m ready for analysis,
I call down to receiving and I pick up the kit, which I do. After that, I bring
it to our toxicology unit, which is our locked lab which only approved
personnel can get into; namely, the forensic scientist working toxicology and
also the supervisors and management.
After the kit is taken into the lab, it’s then locked in our refrigerator,
which has key to it, and it stays there until I’m ready to analyze the blood kit.
At that point, that blood kit is taken out and we run our analysis in
batches . . . . But . . . only one kit is opened at one time to make sure there’s
no tube switching, and I make sure that the numbers on the kit corresponds
with the evidence kit itself.
After I make sure of that . . . we [test] two vials for quality assurance.
The results have to be duplicated. After that, I . . . make a sequence. And after
I check the sequence with the worksheet, make sure it corresponds to the
evidence kit itself, I run the instrument and the instrument prints out the results
after it’s finished the analysis. And I review the analysis and submit the
findings to our . . . Chemical Testing for Alcohol Unit . . . they send a report
to me, I review it and sign it after I make sure everything is correct.
-4-
Mr. Shu explained that, in this case, he received appellant’s blood kit from “our
[central] receiving unit,” and he “put it into the refrigerator in our toxicology unit until [he]
was ready to analyze the blood.” When he was ready, he took it out of the refrigerator,
“sampled it,” and then followed the testing procedure that he outlined for the jury. After the
blood sample was analyzed, a report was printed, and he wrote down the results. Once he
received the final report, he made sure the information was correct, and he signed the report.
The State then moved into evidence, as State’s Exhibit #13, the report indicating Mr.
Shu’s findings. Appellant objected, arguing that the “State has not established chain of
custody. They haven’t established that the blood that was taken by this phlebotomist, Mr.
Russom, was the blood that was analyzed by this particular witness.” Appellant asserted that
the parties did not “have the actual blood kit that was taken, the actual blood that was taken,
the vials, the cardboard box, any of the notations on the cardboard box.” Instead, all the
parties had was State’s Exhibit #14, “which would have been the only marking or only
indication of what was actually given to” Mr. Shu, and Mr. Shu had indicated that the exhibit
was “not what was provided to him,” but rather, it was only “similar.” Thus, he concluded,
the State had not established that the blood that was drawn was the same blood that was
analyzed by Mr. Shu.
The court then allowed the State to further examine Mr. Shu about the condition of
the blood collection kit when he received it. Mr. Shu explained that he had received the
package from the police Central Receiving Unit. The blood collection kit was a cardboard
-5-
box with evidence tape over it to seal it. Mr. Shu broke the “evidence seal and opened the
cardboard box. Inside the box was a “plastic clam shell that has evidence seals alongside of
it.” Mr. Shu broke the seals on the “clam shell” to get to the two test tubes, and he ensured
that there was no evidence of tampering.
After that testimony, the State again sought to admit into evidence the results of
appellant’s blood alcohol test. Appellant objected, arguing that Mr. Shu had indicated that
he received the package via hand-delivery, and Officer Fox had testified that he had mailed
the kit. He asserted that there was a “hole in the chain of custody,” and “if we had the vials
and the cardboard kit and the attached signatures on that cardboard kit, then perhaps the State
could establish chain of custody. We don’t have that. All we have at this point is . . . State’s
Exhibit 14, which doesn’t indicate anything at this point.”
The court overruled appellant’s objection. State’s Exhibit #13, along with Mr. Shu’s
testimony regarding the results of Mr. Shu’s testing of appellant’s blood, was admitted.
Appellant’s blood alcohol concentration was .24 grams of alcohol per 100 ml of blood.
On cross-examination, appellant asked Mr. Shu about the difference between State’s
Exhibit #14 and Mr. Shu’s copy of the form. Mr. Shu explained that his copy had the same
top portion, but it had a “bottom tear off that says laboratory use.” He stated: “Basically, it
has a portion where I can note the condition of the seal,” and in “this case, I know the seal
was okay.
-6-
On redirect, Mr. Shu stated that the form that he had brought with him to court was
different from State’s Exhibit #14 in that the exhibit “does not include the laboratory tear off
copy of [his] signature and [his] statement which [he] wrote on” the form. Other than that,
the forms were identical.
B.
Chain of Custody
Appellant argues that the State failed to establish the necessary chain of custody
between the blood drawn by Mr. Rossum and the blood tested by Mr. Shu. Noting that
Corporal Fox testified that he sent the blood collection kit through the mail to the Maryland
State Police, and Mr. Shu testified that he obtained the kit from the Receiving Unit of the
Maryland State Police, appellant argues that there was a “‘hole in the chain of custody,’ as
the items were handled and transferred by numerous unknown people, both throughout the
postal service en route to the State Police, and by people within the State Police Receiving
Unit before [being] retrieved by Mr. Shu.” Moreover, he argues, there “was no evidence that
the chain of custody documentation in State’s Exhibit 14 accompanied those items during the
journey and remained attached to those particular items throughout those undocumented parts
of their journey.” In addition, as Mr. Shu testified that there was a portion of State’s Exhibit
#14 missing, there was no evidence that the exhibit “was full, complete, and accurate.”
The State contends that it is not necessary for the State to “present testimony from
every human being who touched an item before that evidence may be admitted into
-7-
evidence,” nor is there “any requirement that the State provide any written documentation
whatsoever concerning chain of custody.” It asserts that the authenticity of an item offered
at trial may be established almost entirely by circumstantial evidence, and the only issue
before the court is whether the evidence presented is sufficient to support a finding that the
matter in question is what its proponent claims it to be. The State argues that, in this case,
the testimony was sufficient to allow a rational fact finder to determine that the blood tested
by Mr. Shu was the same blood collected from appellant.
With respect to appellant’s argument that there is a “missing” portion of State’s
Exhibit #14, the State responds in two ways. First it asserts that the “missing” portion was
not actually missing, as Mr. Shu had with him a copy of the complete form, which included
the bottom portion. Moreover, it argues, there is nothing in the record to indicate that the
presence or absence of the “missing” portion of the form would prevent the jury from
determining that the unsealed blood vials received by Mr. Shu were the same vials mailed
by Corporal Fox. Indeed, the “part of the form that [Mr.] Shu filled out had nothing to do
with the authentication of the blood when [Mr.] Shu received it.”
Determinations regarding the admissibility of evidence generally are left to the sound
discretion of the trial court. Hajireen v. State, 203 Md. App. 537, 552, cert. denied, 429 Md.
306 (2012). This Court reviews a trial court’s evidentiary rulings for abuse of discretion.
State v. Simms, 420 Md. 705, 724-25 (2011). Accord Nixon v. State, 204 Md. 475, 483
(1954) (reviewing trial court’s ruling excluding evidence based on inadequate chain of
-8-
custody for an abuse of discretion). A trial court abuses its discretion only when “no
reasonable person would take the view adopted by the [trial] court,” or when the court acts
“without reference to any guiding rules or principles.” King v. State, 407 Md. 682, 697
(2009).
Chain of custody evidence is necessary to demonstrate the “ultimate integrity of the
physical evidence.” Best v. State, 79 Md. App. 241, 256, cert. denied, 317 Md. 70 (1989).
In most cases, an adequate chain of custody is established through the testimony of key
witnesses who were responsible for the safekeeping of the evidence, i.e., those who can
“‘negate a possibility of “tampering” . . . and thus preclude a likelihood that the thing’s
condition was changed.’” Jones v. State, 172 Md. App. 444, 462 (quoting Wagner v. State,
160 Md. App. 531, 552 (2005)), cert. denied, 399 Md. 33 (2007). What is necessary to
negate the likelihood of tampering or of change of condition will vary from case to case.
Best, 79 Md. App. at 250. The existence of gaps or weaknesses in the chain of custody
generally go to the weight of the evidence and do not require exclusion of the evidence as
a matter of law. See Jones, 172 Md. App. at 463 (upholding the admission of the evidence,
but noting that the gaps in the State’s chain of custody supported defense counsel’s remarks
in closing that the jury should discount its value).
Here, the evidence showed that Corporal Fox responded to the hospital with a blood
collection kit that was “new, unopened, and it was still within its expiration period.” He then
observed the phlebotomist, Mr. Rossum, draw blood from appellant. Mr. Rossum then
-9-
sealed the vials, and Corporal Fox placed them in a secured container, which was then
“sealed into a bag,” and then placed in the cardboard box. The box was then mailed to the
Maryland State Police Crime Lab, where Mr. Shu took possession of the box, with its seals
still intact. The box was kept in a locked and secure area of the crime lab while Mr. Shu
performed his analysis. Mr. Shu testified that he inspected the cardboard box, in which the
blood was delivered, the interior container protecting the vials, as well as the vials
themselves, before performing his tests, and he saw no evidence of any tampering. This
chain of custody evidence was sufficient to allow a rational fact finder to determine that the
blood Mr. Shu tested was the same blood that Mr. Rossum collected from appellant and
turned over to Corporal Fox.
II.
Admission of the SUV’s Recorded Data
Appellant next contends that the circuit court “erred in permitting the State to offer
evidence derived from the air bag control module of [appellant’s] vehicle because there was
no evidence that the data was based upon a reliable methodology.” The State contends that
appellant is wrong and “misapprehends the standard for the admission of both scientific
evidence and expert testimony.”
-10-
A.
Proceedings Below
Corporal Frank Carson, a member of the Prince George’s County Police Department,
investigated the collision. He testified at trial, without objection, as an expert witness in
crash data retrieval and air bag control module analysis. During voir dire, Corporal Carson
testified that he had been an accident reconstructionist for 15 years. He described the
training and experience he had regarding how to use specialized equipment to retrieve “crash
data” from vehicle air bag control modules, as well as how to analyze that information “as
it applies to accident reconstruction and crashes.” Corporal Carson had qualified as an expert
in crash data retrieval for air bag control modules on two prior occasions.
After he was accepted as an expert, Corporal Carson explained that the air bag control
module determines whether a vehicle’s air bag should deploy by measuring “deceleration and
time.” Analogizing to a parachute that opens on impact, which is not helpful, he noted that
an air bag must be deployed prior to impact to be effective. The module attempts to predict
when a collision is imminent by measuring the severity of rapid decelerations. Although
Corporal Carson knew how to retrieve and analyze “crash data” from the air bag control
module, he acknowledged that he did not know the specific “engineering parameters” that
the module used in determining whether to deploy the air bag, stating that this was “a trade
secret.”
-11-
With respect to the collision in this case, as part of the investigation, Corporal Carson
removed the air bag control module from appellant’s SUV. He attached the module to a
“special interface,” and then attached that to a computer running a particular program. He
then was able to retrieve the data from the module and download the information from the
module to his computer. Software on his computer then produced “a readable formatted
report” of the data retrieved from the module. The method he used to retrieve the data is
“accepted within the scientific community of reconstructionists.”
The State then offered into evidence, as State’s Exhibit #12, the report Corporal
Carson generated. Appellant objected to the admission of the report, as well as Corporal
Carson’s testimony regarding the report, on the ground that the State had not established the
reliability of the data. He argued that Corporal Carson’s testimony was “simply saying this
is what the computer shows or the computer system shows in the vehicle, but there’s no
indication that that computer system is reliable.” Moreover, he asserted that the “retrieval
tool” used to collect the data was version “4.0,” and he proffered to the court that the “latest
software . . . is actually a version 10.3.” Counsel directed the court to the “warning at the top
of this State’s Exhibit Number 12 that the latest retrieval system or latest software should be
used.”
The court asked if counsel had any cases addressing the reliability of the crash
retrieval system, and counsel said that he did not “have any with me right now.” The court
then allowed the prosecutor to ask additional questions.
-12-
Corporal Carson testified that he had investigated 175 fatal motor vehicle collisions,
including cases in which air bag control modules and crash data retrievals had been involved.
With respect to his opinion regarding the reliability and accuracy of “crash data retrieval,”
Corporal Carson stated that, in his experience as an accident reconstructionist, “air bag
control modules are very accurate, especially if they’re involved in cases in the direction
they’re designed to sense,” meaning forward and backward decelerations. He stated that
National Traffic Safety Administration (“NTSA”) studies have shown that the modules were
accurate to “between a half and two miles an hour, in most cases.”
The court ultimately overruled appellant’s objection.1 It stated that appellant’s
argument went “more towards whatever argument you want to make in terms of the weight
the jury should give to it, but the [c]ourt is satisfied that it’s admissible.”
Corporal Carson then discussed the data retrieved from the air bag control module.
He testified that, one second prior to the crash, the vehicle was going 89 miles per hour, the
brake was not applied, and the air bag did not deploy.
B.
Basis for Expert Opinion
Appellant contends that the court erred in allowing the testimony derived from the air
bag control module of his SUV because the State “offered no information concerning the
1

for testimony must be laid, but the court stated that the facts were “completely
distinguishable from the situation” in this case.
-13-
reliability of the system used to record and relate that data.” Therefore, he asserts, Corporal
Carson did not have a sufficient factual basis for his expert testimony.
The State contends that, contrary to appellant’s position, it “is not necessary for an
expert to be able to describe, in detail, the software code used to retrieve information.”
Rather, “it is enough that the information [the expert] relied upon is of a type generally relied
upon by similar experts.” In this case, it asserts that “there was direct testimony that the
module was a reliable and accurate source of data in general.” Moreover, “any complaints
regarding the accuracy of the information recorded by the control module in [appellant’s] car
went to its weight, not its admissibility.”
The decision whether to admit or exclude expert testimony is a matter within the
discretion of the trial court, and the court’s decision in this regard “‘will seldom constitute
a ground for reversal.’” Donati v. State, 215 Md. App. 686, 742 (quoting Bryant v. State,
393 Md. 196 (2006)), cert. denied, 438 Md. 143 (2014). Accord Massie v. State, 349 Md.
834, 851 (1998) The court’s decision will be reversed only if it constitutes an abuse of
discretion, Stevenson v. State, ___ Md. App. ___, No. 2018, Sept. Term, 2013, slip op. at 11
(filed April 2, 2015) (quoting Massie, 349 Md. at 850-51), which occurs when a decision is
“‘well removed from any center mark imagined by the reviewing court and beyond the fringe
of what the court deems minimally acceptable.’” In re Ashley S., 431 Md. 678, 704 (2013)
(quoting In re Yve S., 373 Md. 551, 583-84 (2003)).
Maryland Rule 5-702 governs the admissibility of expert testimony:
-14-
Expert testimony may be admitted, in the form of an opinion or otherwise, if
the court determines that the testimony will assist the trier of fact to understand
the evidence or to determine a fact in issue. In making that determination, the
court shall determine (1) whether the witness is qualified as an expert by
knowledge, skill, experience, training, or education, (2) the appropriateness of
the expert testimony on the particular subject, and (3) whether a sufficient
factual basis exists to support the expert testimony.
Appellant’s claim rests on the third prong, whether Corporal Carson had a sufficient factual
basis for his opinion. Appellant asserts that he did not because the State failed to establish
that his testimony was supported by a reliable process or methodology. We disagree.
To be sure, “simply because a witness has been tendered and qualified as an expert
in a particular occupation or profession, it does not follow that the expert may render an
unbridled opinion, which does not otherwise comport with Md. Rule 5-702.” Giant Food,
Inc. v. Booker, 152 Md. App. 166, 182, cert. denied, 378 Md. 614 (2003). Rather, “[a]n
expert’s opinion testimony must be based on [an] adequate factual basis so that it does not
amount to ‘conjecture, speculation, or incompetent evidence.’” Id. at 182-83 (quoting Uhlik
v. Kopec, 20 Md. App. 216, 223-24 (1974)). Accord City Homes, Inc. v. Hazelwood, 210
Md. App. 615, 678-79, cert. denied, 432 Md. 468 (2013).
The parties have not cited, and we have not found, any Maryland case addressing the
issue regarding the reliability of vehicle air bag control modules. Other jurisdictions,
however, have concluded that “black box” data from a motor vehicle’s recording system,
is reliable and admissible.
-15-
In Com. v. Zimmermann, 873 N.E.2d 1215 (Mass. App. Ct. 2007), in a trial for motor
vehicle homicide by negligent operation, the Appeals Court of Massachusetts agreed with
the trial court that evidence taken from the event data recorder (EDR) in the defendant’s
vehicle was sufficiently reliable to be admissible. The Commonwealth’s expert had
conducted 200 tests on EDRs, and he testified that the technology behind the EDR had been
known for many years, that he and other experts had found the EDRs to be reliable, that
EDRs needed no maintenance and calibration for 10 years, and that his calculations based
on the physical and other evidence were consistent with the EDR data from the defendant’s
vehicle. Id. at 1220. Under these circumstances, the appellate court held that the trial court
did not abuse its discretion in finding that the EDR data was reliable and admissible. Id. at
1221.
Similarly, in People v. Christmann, 776 N.Y.S.2d 437, 315 (N.Y. Justice Ct. 2004),
the court held, in a prosecution for speeding and failing to exercise due care, that accident
data recorded in a motor vehicle’s sensing diagnostic module (SDM) was admissible because
it was reliable. It held that such evidence was “generally accepted as reliable and accurate
by the automobile industry and [NTSA].” See Bachman v. Gen’l Motors Corp., 776 N.E.2d
262, 281 (“crash sensors such as the SDM have been in production in automobiles for over
a decade” and are generally accepted as a tool of accident reconstruction), appeal denied, 787
N.E.2d 154 (Ill. App. Ct. 2002).
-16-
Here, Corporal Carson, who had extensive training and experience in how to use
specialized equipment to retrieve data from control modules, had qualified as an expert in
crash data retrieval from air bag modules on two different occasions. As the State notes, he
testified that the method he used to retrieve the data was accepted within the scientific
community of reconstructionists, and that, in his experience, air bag control modules are very
accurate. He also testified that NTSA studies have shown them to be accurate.
The testimony here regarding the reliability of the air bag control module was not
extensive. It was sufficient, however, for us to conclude that the circuit court did not abuse
its discretion in determining that “black box” data derived from the air bag control module
of appellant’s SUV was sufficiently reliable to support the expert’s testimony.
