OPINION

¶1 Following a jury trial held in the circuit court of Cook County, defendant Keith Nelson
was found guilty of one count of aggravated kidnaping and three counts of aggravated
criminal sexual assault. The trial court sentenced defendant to four consecutive 25-year terms
in the Illinois Department of Corrections. Defendant now appeals, arguing: (1) the trial court
erred in allowing the State to introduce “other crimes” evidence to show defendant’s intent,
motive and propensity to commit sex crimes; and (2) his constitutional right to confront the
witnesses against him was violated by the State’s presentation of expert testimony from a
DNA analyst. For the following reasons, we affirm.

¶2 BACKGROUND
¶3 Defendant was charged by indictment with aggravated kidnaping and aggravated criminal
sexual assault. The charges arose from a May 26, 2006, incident in which C.G. was forcibly
taken to the backyard of a building at 7214 South Calumet Avenue in Chicago, where she
was sexually assaulted.
¶4 Prior to trial, the State filed a motion in limine to introduce “other crimes” evidence
demonstrating defendant sexually assaulted S.C. in a separate incident. Pursuant to section
115-7.3 of the Code of Criminal Procedure of 1963 (Code) (725 ILCS 5/115-7.3 (West
2006)), the State sought to introduce this evidence to establish not only defendant’s intent
and motive, lack of consent, modus operandi and common scheme or design, but also his
propensity to commit sex offenses, based on the proximity and time and similarity of the
assaults against C.G. and S.C. Following a hearing, the trial court granted the State’s motion,
over the defendant’s objection that the evidence was more prejudicial than probative.
¶5 The State also filed a pretrial motion in limine seeking to present DNA evidence through
testimony from Matthew Quartaro of Orchid-Cellmark (Cellmark), a private laboratory
which performs DNA analyses for law enforcement agencies, criminal defense lawyers and

-2-
 private individuals. The motion indicated Cellmark conducted DNA testing in this case. The
State acknowledged Quartaro “is not the analyst who performed the mechanical aspects of
the DNA testing,” but he was one of the forensic supervisors who bears responsibility for
Cellmark’s DNA testing. The State also asserted Quartaro reviewed the data generated by
the analysts who worked on this case, checked the work to ensure it was done properly,
verified the chain of custody and ensured the evidence was properly stored and handled, and
ultimately he reached independent conclusions from the test data. At the hearing on the
motion, defense counsel objected on the grounds Quartaro’s testimony was hearsay and
would violate defendant’s right to confront the witnesses against him under the sixth
amendment to the United States Constitution. The trial court granted the State’s motion.
¶6 At trial, C.G. testified that in May 2006, she was 17 years old and living with her cousin
at 7208 South Calumet Avenue in Chicago. On May 25, 2006, C.G.’s boyfriend dropped her
off in front of her residence at approximately 11 or 11:30 p.m. C.G. did not have a key, so
she rang the doorbell, but no one answered. C.G. told her boyfriend he could leave because
her cousin’s best friend, Ashley, and a boy named Jordan were sitting in a parked automobile
in front of the residence. C.G. talked with Ashley and Jordan until Ashley left. C.G. and
Jordan then drove the automobile around the block to get something to eat, after which they
returned to the residence. According to C.G., Jordan said he had to leave, so C.G. exited the
vehicle and sat on the front porch for a while.
¶7 C.G. testified she became impatient and decided to walk to the corner of 72nd Street and
Calumet Avenue. When C.G. reached the corner she noticed a man she later identified as
defendant walking toward her. C.G. turned around and commenced walking back toward her
residence. According to C.G., defendant approached her and asked, “What’s your name?”
C.G. also testified defendant was wearing a black sleeveless shirt, shorts and a black,
fingerless glove. C.G. described defendant as muscular, with “a lot of facial hair” and “a lot
of tattoos.” C.G. specifically noticed tattoos of the face of Jesus and a cross on his left side.1
¶8 C.G. further testified she did not want to speak to defendant, so she provided false
answers to his questions. When C.G. and defendant reached the portion of the street opposite
the residence, C.G. requested the use of defendant’s cell phone. Defendant handed C.G. the
cell phone and she dialed her cousin’s telephone number, but there was no response. C.G.
returned the cell phone to defendant and said goodbye.
¶9 According to C.G., as she stepped in front of the residence, defendant lunged at her. C.G.
testified defendant attempted to grab her and she struck him. C.G. also testified defendant
grabbed her right hand and bit her below the thumb. C.G. further testified defendant punched
her face several times. When C.G. began screaming for defendant to stop, he placed his
forearm against her throat and choked her. C.G. began to lose consciousness and fell to the
ground.
¶ 10 C.G.’s next recollection was defendant walking her down 72nd Street and turning into
an alley. C.G. testified she again lost consciousness and, when she regained it, realized

1
Though C.G. testified the tattoo was on defendant’s left side, the record on appeal includes
a photograph showing these tattoos are located on defendant’s left upper arm.

-3-
 defendant had pinned her against the wall of a garage with his arm. According to C.G.,
defendant ordered her to remove her clothes. When she refused, defendant ripped her pants
open and forced her to the ground on all fours. C.G. further testified defendant again choked
her until she lost consciousness.
¶ 11 When C.G. again regained consciousness, defendant was inserting his penis into her
vagina. C.G. told defendant to stop; defendant responded he would kill her if she did not shut
up. According to C.G., defendant then inserted his penis into her anus, then again in her
vagina, then again in her anus, then again in her vagina. C.G. requested defendant stop
because she needed to defecate. Defendant refused to stop, responding, “If you shit on me,
I’m going to kill you.” C.G. further testified defendant turned her around and forced his penis
into her mouth. Defendant turned C.G. around again, choking her while stating, “I bet the
next time you see me you’re gonna want to talk to me.”
¶ 12 Defendant left the area, in the direction of 72nd Street, while C.G. remained on the
ground. C.G., after waiting a while, walked toward 73rd Street then back down Calumet
Avenue toward 72nd Street. C.G. testified she walked “the long way” because she was afraid
to walk directly toward 72nd Street. According to C.G., she was naked below the waist,
except for socks. As she approached the street, C.G. observed her cousin and screamed her
cousin’s name. C.G. waited on the front porch for the police to arrive. C.G. was hysterical
when the police arrived and had difficulty speaking to them because her throat hurt. C.G. did
not recall whether she had conversations with the first responding police officers. C.G. was
subsequently transported to St. Bernard Hospital by ambulance. C.G. testified she was
examined by physicians there, including swabbing of her mouth, vagina and anus.
¶ 13 C.G. acknowledged she did not know defendant prior to the incident. C.G. testified that
on June 15, 2006, she spoke to a police detective at Area 2 police headquarters and worked
with a sketch artist. On June 2, 2008, C.G. identified defendant as the man who sexually
assaulted her on May 26, 2006, from a photo array shown to her by a police detective. On
June 6, 2008, C.G. identified defendant as her attacker during an in-person lineup. C.G. also
identified photographs depicting: the garage and back yard where the assault occurred; the
clothing she left behind at the scene; the bite mark on her hand and bruises on her arm, elbow
and face following the assault; and the tattoo of the face of Jesus she observed on defendant’s
left arm.
¶ 14 Latoya Jones testified that on May 25, 2006, she lived in a second-floor apartment at
7214 South Calumet Avenue. When she arrived home at approximately 10 p.m., she saw a
young woman who lived at 7208 South Calumet Avenue sitting on her front porch. Later in
the evening, she heard a woman’s screams that sounded as though they came from her yard,
or the next yard over. Jones testified she went to her window, but did not see anything. Jones
did not telephone the police.
¶ 15 Chicago police officer William Stec testified he was employed as an evidence technician
for the Chicago police department for the past 13 years. Officer Stec testified he was working
on the evening of May 25, 2006, into the early morning hours of May 26, 2006. Officer Stec
was assigned to process a crime scene located at 7214 South Calumet Avenue at
approximately 2:20 a.m. Officer Stec photographed the scene and observed blue panties,

-4-
 black pants, a pair of shoes and a silver belt on the grass next to the garage. Officer Stec
recovered and inventoried these items. According to Officer Stec, the pants did not appear
to be torn and the belt buckle was not broken off from the belt.
¶ 16 Dr. Jihun Lee testified he was an emergency room resident at St. Bernard Hospital on
May 26, 2006. Dr. Lee examined C.G. and found no trauma to her external genitalia or anus,
which is not uncommon in sexual assault cases. Dr. Lee observed C.G. had swelling to her
left jaw, bruising on her neck, hemorrhaging and swelling around her eyes, and a bite mark
on her right hand. Dr. Lee opined the injuries around her eyes could be the result of trauma
or choking. Dr. Lee also identified photographs of these injuries.
¶ 17 Maria Duce testified she was a nurse at St. Bernard Hospital on May 26, 2006. Duce
testified she collected samples from C.G. for a sexual assault kit. Duce swabbed C.G.’s
mouth, vagina and anus and took scrapings from under C.G.’s fingernails. Duce identified
the sexual assault kit she prepared.
¶ 18 The parties stipulated that if called as a witness, Nora Alberto would testify she also was
a nurse at St. Bernard Hospital on May 26, 2006, and assisted in C.G.’s treatment. Alberto
would testify the sexual assault kit collected by Dr. Lee was sealed and provided to Chicago
police officer Robert McGivney. The parties also stipulated that if called as a witness, officer
McGivney would testify he was employed as an evidence technician for the Chicago police
department on May 26, 2006. Officer McGivney would also testify he received the sexual
assault kit and a bag of clothing at St. Bernard’s Hospital, both of which he inventoried.
¶ 19 Jennifer Bell, a forensic scientist for the Illinois State Police, testified she received the
sexual assault kit for C.G.’s case on August 22, 2007. According to Bell, C.G.’s vaginal and
anal swabs both tested positive for the presence of semen, but the oral swab did not. Bell
preserved all of the swabs, along with C.G.’s blood standard, for DNA testing.
¶ 20 Quartaro, who supervises a team of eight DNA analysts at Cellmark, as well as testing
samples himself, was declared an expert in the field of forensic DNA analysis without
objection. Quartaro testified Cellmark was asked to perform forensic DNA analysis on
samples under a Cellmark case number associated with a Chicago police department case
number. According to Quartaro, on January 16, 2008, Cellmark received a vaginal swab, a
rectal swab and a reference blood sample from C.G. to determine whether Cellmark could
identify any unknown DNA from the swabs.
¶ 21 Quartaro described the procedures utilized at Cellmark, which works in an assembly line
or team format, so that people who excel at specific tasks perform those specific tasks.
According to Quartaro, there are individuals who examine the evidence to determine which
portions are sent for DNA testing. There are also individuals who extract or purify DNA
from those samples. Quartaro testified the bulk of the work is performed by robotic
instrumentation in the wet chemistry lab. Finally, there are individuals who examine the data
generated from this process and prepare a report.
¶ 22 Quartaro further testified that in this case, he examined the evidence received from the
Illinois State Police and took cuttings to send for DNA testing. Quartaro also reviewed the
data and documentation and performed the analysis on the data generated from the case.
Quartaro authored the report in this case for Cellmark.

-5-
¶ 23 Quartaro testified Cellmark was able to obtain a DNA profile from the reference blood
standard collected from C.G. Cellmark had information that semen previously had been
identified from C.G.’s vagina and rectal swabs. A DNA profile for C.G. was identified from
the swabs, as was a DNA profile for an unknown male. Quartaro further testified, over a
defense objection, that the proper controls were run in this case to ensure the instruments
were functioning properly. In addition, Quartaro testified, again over a defense objection, that
a proper chain of custody was maintained over the samples at all times. Cellmark then
shipped the remaining evidence to the Illinois State Police. Quartaro testified all of his
conclusions were within a reasonable degree of scientific certainty.
¶ 24 On cross-examination, Quartaro acknowledged he did not personally receive the evidence
in this case and he did not know where or under what conditions the evidence was stored
prior to January 16, 2008. Quartaro also acknowledged other individuals performed the
purification of the DNA samples and oversaw the robotic instrumentation in this case.
Quartaro testified he analyzed the data and wrote the report and there was another person,
named Kelly Bird, who conducted a technical review of his report. When defense counsel
asked whether it was Kelly Bird’s job to summarize what had transpired, Quartaro responded
Bird’s job was to review the documentation and data in the case file and then examine his
report to ensure they both drew the same conclusions.
¶ 25 Defense counsel also asked how Quartaro knew Cellmark’s controls were in proper
order. Quartaro explained Cellmark runs two controls at each stage of the process. The first
is a negative control used to ensure Cellmark is not introducing any DNA into samples
during processing. The second is a positive control, which is a known sample used to
determine the process is working correctly. According to Quartaro, the documentation
reflected the process worked correctly in this case.
¶ 26 Chicago police detective Connolly testified that on May 30, 2008, he learned defendant’s
DNA was contained in a database and defendant’s DNA profile matched the previously
unidentified male in C.G.’s case. On June 2, 2008, he showed C.G. a photo array, from
which she identified defendant as the person who sexually assaulted her on May 26, 2006.
Detective Connolly testified he issued an investigatory alert for defendant, but did not obtain
an arrest warrant. On June 19, 2008, Detective Connolly observed defendant at 7908 South
Wabash Avenue. When Detective Connolly ordered defendant to stop, defendant ran inside,
where Detective Connolly discovered him in a locked closet. Detective Connolly placed
defendant in custody and escorted him to Area 2 police headquarters. Detective Connolly
testified C.G. identified defendant as her assailant during an in-person lineup conducted the
following day.
¶ 27 Ralph Vucko, an investigator employed by the Cook County State’s Attorney’s office,
testified that on June 20, 2008, he took a buccal swab sample from defendant’s mouth.
Vucko also testified he placed the swab in a security locker and transported it to the Chicago
police department on June 26, 2008.
¶ 28 Ronald Tomek, a forensic scientist employed by the Illinois State Police Forensic Science
Center, was proffered as an expert in forensic DNA analysis without objection. Tomek
testified that on July 2, 2008, he received defendant’s buccal swab from the Chicago police

-6-
 department and was able to obtain a DNA profile suitable for comparison from that swab.
On July 28, 2008, Tomek compared the DNA profile he generated from defendant’s buccal
swab with the male DNA profile generated by Cellmark from the vaginal and rectal swabs
taken from C.G. Using a chart with columns representing the profiles generated from the
buccal, vaginal and rectal swabs, Tomek opined the DNA profiles matched at each of the 13
loci tested. According to Tomek, that particular profile is expected to occur in approximately
1 in 2.5 quintillion blacks, 1 in 107 quintillion whites, and 1 in 25 quintillion Hispanics.
Tomek opined the DNA profile from the vaginal and rectal swabs matched defendant’s DNA
profile.
¶ 29 S.C. testified she was 18 years old in 2006. On May 5, 2006, after leaving a party, S.C.
returned to her aunt’s home at 646 E. 90th Street, where she was living at the time.
According to S.C., neither her aunt nor her cousin answered the door, so she walked to the
bus stop. At approximately 1 a.m., she telephoned a friend to obtain a number for a taxicab
company, telephoned to request a cab and waited by the bus stop at 87th Street and Martin
Luther King Drive.
¶ 30 S.C. also testified the taxicab did not arrive and she observed a black, four-door truck
pull up and stop in proximity to her. S.C. described the truck as similar to a sports utility
vehicle. S.C. testified a man she later identified as defendant exited the driver’s side of the
vehicle, approached her and asked whether she was waiting for a bus. According to S.C.,
defendant was wearing a red sleeveless jersey at the time and had tattoos on his arms.
¶ 31 S.C. further testified defendant grabbed her arm, put his other arm around her neck and
forced her into the backseat of the truck with him. At this juncture, S.C. noticed another male
occupied the driver’s seat. S.C. pulled on the truck’s door handle, but the door was locked.
The second male drove the truck northward, then turned into an alley.
¶ 32 S.C. testified defendant ordered S.C. to remove her pants. S.C. pleaded with defendant
not to hurt her, but defendant struck her head and choked her until she removed her pants.
According to S.C., defendant also removed his pants and inserted his penis into her vagina
as she pleaded for defendant to stop. The second male said, “Man, just let her go.”
¶ 33 In addition, S.C. testified defendant forced her to perform oral sex on both defendant and
the second male, whom defendant referred to as “Lee.” Defendant also forced S.C. to give
him a hug and a kiss before allowing her to get dressed and releasing her from the vehicle.
Defendant also took her money. S.C. telephoned a friend, who came and escorted her to the
University of Chicago Hospital, where a sexual assault kit was prepared. S.C. recalled
speaking to Detective Connolly at the hospital. S.C. further testified that on January 23,
2008, she identified defendant as her assailant from a photo array Detective Connolly showed
her.
¶ 34 After the State rested its case, defendant moved for a directed finding. The trial court
denied the motion. Defendant rested without presenting evidence on his own behalf.
Following closing arguments and jury instructions, the jury deliberated and found defendant
guilty of one count of aggravated kidnaping and three counts of aggravated criminal sexual
assault (involving penetration of penis to the mouth, vagina and anus).
¶ 35 On July 12, 2010, defendant filed a posttrial motion for a new trial. On July 27, 2010, the

-7-
 trial judge heard and denied defendant’s posttrial motion, then proceeded to a sentencing
hearing. After hearing the evidence in aggravation and mitigation, the trial judge sentenced
defendant to four consecutive 25-year terms in the Illinois Department of Corrections.
Defendant apparently filed a motion to reconsider sentence, although the copy of this motion
included in the record on appeal is undated. On August 26, 2010, the trial judge denied the
motion to reconsider. Defendant filed a timely notice of appeal to this court on the same date.

¶ 36 DISCUSSION
¶ 37 On appeal, defendant argues: (1) the trial court erred in allowing the State to introduce
“other crimes” evidence to show defendant’s intent, motive and propensity to commit sex
crimes; and (2) his constitutional right to confront the witnesses against him was violated by
the admission of Qartaro’s testimony without the testimony of other technicians involved in
the DNA analysis in this case. We address the arguments in turn.

¶ 38 The Admission of “Other Crimes” Evidence
¶ 39 Defendant maintains the trial court abused its discretion in admitting the evidence of the
sexual assault on S.G. Under the common law, “other crimes” evidence generally is
inadmissible if offered only to demonstrate the defendant’s propensity to commit the charged
crime. People v. Donoho, 204 Ill. 2d 159, 169 (2003). Evidence regarding other crimes
generally is admissible if offered to prove intent, modus operandi, identity, motive, absence
of mistake, or any relevant fact other than propensity. Id. at 170. In this case, the State sought
to offer S.G.’s testimony to show not only intent and motive, but also defendant’s propensity
to commit sex crimes.
¶ 40 Section 115-7.3 of the Code (725 ILCS 5/115-7.3 (West 2006)) provides an exception
to the general rule in criminal cases, permitting evidence a defendant charged with
aggravated criminal sexual assault has committed other sexual offenses to show the
defendant’s propensity to commit sex offenses. See Donoho, 204 Ill. 2d at 176. Like the
common law, however, section 115-7.3 permits such evidence to be admitted only if: (1) it
is relevant; and (2) its probative value is not outweighed by its prejudicial effect. Id. at 177-
78. Section 115-7.3 further provides that, in weighing probative value against prejudicial
effect, a court may consider: “(1) the proximity in time to the charged or predicate offense;
(2) the degree of factual similarity to the charged or predicate offense; or (3) other relevant
facts and circumstances.” 725 ILCS 5/115-7.3(c) (West 2006).
¶ 41 Trial courts should “be cautious in considering the admissibility of other-crimes evidence
to show propensity by engaging in a meaningful assessment of the probative value versus the
prejudicial impact of the evidence.” Donoho, 204 Ill. 2d at 186. “When weighing the
prejudicial effect of admission, a court should consider whether the other-crimes evidence
will become the focus of the trial, or whether it might otherwise be misleading or confusing
to the jury.” People v. Perez, 2012 IL App (2d) 100865, ¶ 47. Nevertheless, a trial court’s
decision to admit “other crimes” evidence will not be reversed unless the court abused its
discretion. Donoho, 204 Ill. 2d at 182. A trial court abuses its discretion if its determination
is unreasonable, arbitrary, or fanciful, or if no reasonable person would adopt the court’s

-8-
 view. Id.
¶ 42 Defendant relies primarily upon People v. Johnson, 406 Ill. App. 3d 805, 811 (2010), in
which this court ruled that although factual similarities will increase the probative value of
such evidence, factual dissimilarities will increase the prejudicial effect.2 The Johnson court
ruled it was error (albeit harmless error) to admit “other crimes” evidence in that case, given
the existence of significant dissimilarities between the two assaults, combined with the trial
court’s failure to conduct any sort of “meaningful” analysis of the prejudicial effect of the
other-crimes evidence. Id. at 812. Defendant notes the other uncharged assault in Johnson
was dissimilar from the charged offense insofar as it involved two assailants, the use of a
vehicle, and nonidentical types of penetration. See id. at 807-08. Defendant thus argues
Johnson is controlling here.
¶ 43 Defendant’s analysis of Johnson is incomplete. The Johnson court noted those
dissimilarities, but also noted in the other, uncharged offense, the victim testified defendant
blew cocaine in her face and gave her alcohol during the assault, and anally penetrated
her–two additional circumstances which differed from the assault testimony from the victim
of the charged offenses. Id. at 811. This court also noted the similarities in Johnson were
general in nature: (1) both victims were abducted while walking past alleys; (2) both victims
were taken to an abandoned building before being assaulted; (3) the assailant used physical
force and threatened to kill both victims if they did not comply with his demands; (4)
defendant vaginally and orally penetrated both victims with his penis; and (5) both victims
were adults when the assaults occurred–one victim was 42 years old and the other was 33
years old. Id.
¶ 44 This case lacks some of the dissimilarities found in Johnson. Moreover, the similarities
here are stronger than in Johnson. For example, the offenses in this matter occurred within
a three-week span of each other; in Johnson, one assault occurred on March 2, 2002, while
the other did not occur until November 9, 2003. Id. at 806-07. The ages of the victims were
also closer–17 and 18 years old–than those in Johnson. Although Johnson does not discuss
the location of the assaults, the record shows the assaults here both occurred on the south
side of Chicago. In Johnson, the charged assault occurred at 9:30 p.m., while the other
occurred during the early evening at 5 p.m. Id. In contrast, both assaults in this case occurred
in the early morning hours. In addition, both assaults in this case specifically involved
defendant choking the victims and striking both in the head.
¶ 45 Furthermore, unlike Johnson, the transcript of the hearing on the State’s motion in this
case demonstrates the trial judge engaged in a meaningful analysis of both the similarities
and dissimilarities between the two assaults in this case. The transcript indicates the trial

2
Defendant also argues the assaults at issue here were less similar than those at issue in
Donoho, People v. Boand, 362 Ill. App. 3d 106 (2005), and People v. Boyd, 366 Ill. App. 3d 84
(2006). Our supreme court has held “[w]here such evidence is not being offered under the modus
operandi exception, ‘mere general areas of similarity will suffice’ to support admissibility.” Donoho,
204 Ill. 2d at 184 (quoting People v. Illgen, 145 Ill. 2d 353, 372-73 (1991)). The existence of
differences between the offenses does not necessarily defeat admissibility, as no two offenses are
identical. Donoho, 204 Ill. 2d at 185 (citing Illgen, 145 Ill. 2d at 373).

-9-
 judge decided to admit the evidence after “acknowledging there are some dissimilarities,”
particularly the number of assailants and the use of a car in the uncharged offense, in light
of the similarities, particularly the proximity in time and location of the offenses. Given the
record in this case, we conclude the trial court’s ruling was not unreasonable, arbitrary, or
fanciful, and a reasonable person could adopt the court’s view. Accordingly, we conclude the
trial court did not abuse its discretion in admitting the evidence of the assault on S.G.
Donoho, 204 Ill. 2d at 182.3

¶ 46 Admission of the DNA Testimony
¶ 47 Lastly, defendant argues his constitutional right to confront the witnesses against him was
violated where the trial court admitted Quartaro’s testimony regarding Cellmark’s DNA
analysis, because Quartaro was not the technician who personally oversaw the robotic testing
of the DNA samples at issue here. The sixth amendment’s confrontation clause provides
“[i]n all criminal prosecutions, the accused shall enjoy the right *** to be confronted with
the witnesses against him.” U.S. Const., amend. VI. This part of the sixth amendment is
known as the confrontation clause and applies to the states through the fourteenth
amendment. People v. Stechly, 225 Ill. 2d 246, 264 (2007). The issue of whether defendant’s
sixth amendment confrontation rights were violated involves a question of law, which we
review de novo. People v. Lovejoy, 235 Ill. 2d 97, 141-42 (2009).
¶ 48 In Crawford v. Washington, 541 U.S. 36, 68 (2004), the United States Supreme Court
held the confrontation clause bars the admission of testimonial statements of a witness who
did not appear at trial unless he was unavailable to testify, and the defendant had a prior
opportunity for cross-examination. The Court declined to specifically define what constitutes
a “testimonial” statement, but gave some guidance on the question: “Whatever else the term
covers, it applies at a minimum to prior testimony at a preliminary hearing, before a grand
jury, or at a former trial; and to police interrogations” Id. at 68. The Crawford Court further
opined “[t]he [Confrontation] Clause also does not bar the use of testimonial statements for
purposes other than establishing the truth of the matter asserted.” Id. at 59 n.9.
¶ 49 In subsequent cases, the Court has further clarified. In Davis v. Washington, 547 U.S.
813, 822 (2006), the Court elaborated on what makes an out-of-court statement
“testimonial,” distinguishing between two types of statements that might be made to a police
officer. One category of statement is nontestimonial; the other is testimonial:
“Statements are nontestimonial when made in the course of police interrogation under

Defendant claims the evidence was unfairly prejudicial, even if properly admitted, based
on the State’s closing argument. Defendant relies on People v. Bedoya, 325 Ill. App. 3d 926, 938
(2001), which did not involve evidence introduced to show propensity. The State, having properly
sought the admission of this evidence to show propensity, was entitled to argue the point. The State
is afforded a great deal of latitude in presenting closing argument and is entitled to argue all
reasonable inferences from the evidence. See, e.g., People v. Nieves, 193 Ill. 2d 513, 532-33 (2000).
In addition, having found no abuse of discretion in admitting the testimony, this court need not
address defendant’s argument that the prejudice therefrom was not harmless error in this case.

-10-
 circumstances objectively indicating that the primary purpose of the interrogation is to
enable police assistance to meet an ongoing emergency. They are testimonial when the
circumstances objectively indicate that there is no such ongoing emergency, and that the
primary purpose of the interrogation is to establish or prove past events potentially
relevant to later criminal prosecution.” Id.
The Davis Court recognized this last clause–“that the purpose *** is to establish or prove
past events potentially relevant to later criminal prosecution”–could apply to out-of-court
statements not made during police interrogations. The Court limited its holding in this way
because the statements at issue in Davis were made during police interrogations. In a
footnote, however, the Court clarified it did not mean to “imply *** that statements made
in the absence of any interrogation are necessarily nontestimonial.” Id. at 822 n.1.
¶ 50 Justice Thomas objected to the majority’s primary purpose test as unpredictable. Id. at
834 (Thomas, J., concurring in the judgment in part and dissenting in part). According to
Justice Thomas, out-of-court statements that lack “some degree of solemnity” are not
testimonial in nature. Id. at 836 (Thomas, J., concurring in the judgment in part and
dissenting in part). He would find affidavits, depositions, prior testimony, and confessions
sufficiently solemn “to constitute formalized statements” subject to the rule established by
Crawford. Id. at 836-37 (Thomas, J., concurring in the judgment in part and dissenting in
part).
¶ 51 Subsequently, the Supreme Court has issued varying opinions applying Crawford to the
admission of forensic reports and testimony. In Melendez-Diaz v. Massachusetts, 557 U.S.
305 (2009), the issue was whether a certificate from a state laboratory attesting the substance
analyzed was cocaine was testimonial hearsay when offered in evidence against a defendant
charged with drug distribution and trafficking. The Melendez-Diaz Court, in a 5 to 4
decision, ruled the forensic analyst’s certificates were within the “core class of testimonial
statements” in Crawford. Id. at 310. The Supreme Court found “[t]he ‘certificates’ are
functionally identical to live, in-court testimony, doing ‘precisely what a witness does on
direct examination.’ ” Id. at 310-11 (quoting Davis v. Washington, 547 U.S. 813, 830
(2006)). Indeed, under Massachusetts law, the sole purpose of the affidavit was evidentiary.
Melendez-Diaz, 557 U.S. at 311. Accordingly, the Court concluded the introduction of the
certificate in violation of the confrontation clause was error under Crawford. See id. at 329.
¶ 52 Two other aspects of Melendez-Diaz are particularly notable for the purpose of this
appeal. First, the majority opinion noted in partial response to the dissent:
“[W]e do not hold, and it is not the case, that anyone whose testimony may be relevant
in establishing the chain of custody, authenticity of the sample, or accuracy of the testing
device, must appear in person as part of the prosecution’s case. While the dissent is
correct that ‘[i]t is the obligation of the prosecution to establish the chain of custody,’
post, at [335], this does not mean that everyone who laid hands on the evidence must be
called. As stated in the dissent’s own quotation, ibid., from United States v. Lott, 854
F.2d 244, 250 (C.A.7 1988), ‘gaps in the chain [of custody] normally go to the weight
of the evidence rather than its admissibility.’ It is up to the prosecution to decide what
steps in the chain of custody are so crucial as to require evidence; but what testimony is

-11-
 introduced must (if the defendant objects) be introduced live. Additionally, documents
prepared in the regular course of equipment maintenance may well qualify as
nontestimonial records.” Melendez-Diaz, 557 U.S. at 311 n.1.
Second, Justice Thomas, a deciding vote, wrote a concurrence distancing himself from
consideration of the purpose of the out-of-court statement and repeating his prior position
that the confrontation clause is implicated only by extrajudicial statements “ ‘contained in
formalized testimonial materials.’ ” Id. at 329 (Thomas, J., concurring) (quoting White v.
Illinois, 502 U.S. 346, 365 (1992) (Thomas, J., concurring in part and concurring in the
judgment, joined by Scalia, J.)).
¶ 53 In Bullcoming v. New Mexico, 564 U.S. ___, 131 S. Ct. 2705 (2011), the Supreme Court
considered whether a defendant in a prosecution for driving while under the influence of
intoxicating liquor had the right under the sixth amendment to confront the analyst who
certified the blood-alcohol analysis report. Id. at ___, 131 S. Ct. at 2710. The prosecution had
admitted the test results through the testimony of a scientist other than the one who
performed the test. Id. at ___, 131 S. Ct. at 2709. The Court concluded the blood-alcohol test
results were testimonial in nature because the report was “created solely for an ‘evidentiary
purpose’ *** in aid of a police investigation.” Id. at ___, 131 S. Ct. at 2717 (quoting
Melendez-Diaz, 557 U.S. at 311). The absence of formal certification or notarization of the
report did not remove it from the scope of the confrontation clause, because the formalities
attending the creation of the report and its purpose were “more than adequate” to classify it
as testimonial. Id. at ___, 131 S. Ct. at 2717.
¶ 54 Bullcoming, like Melendez-Diaz, produced a divided opinion. Justice Ginsburg wrote for
the majority, but Justices Thomas and Kagan joined only in part. Notably, Justice Thomas
did not join footnote 6 of the majority opinion, which again tied the question of whether a
statement is testimonial to the “primary purpose” of the out-of-court statement. See id. at ___
n.6, 131 S. Ct. at 2714 n.6.
¶ 55 Moreover, Justice Sotomayor joined in part and filed a separate opinion concurring in
part in Bullcoming. In her partial concurrence, Justice Sotomayor highlighted four facts not
presented by the case, three of which are potentially relevant to this appeal. First, the person
testifying was not “a supervisor, reviewer, or someone else with a personal, albeit limited,
connection to the scientific test at issue.” Id. at ___, 131 S. Ct. at 2722 (Sotomayor, J.,
concurring in part). Second, the expert was not “asked for his independent opinion about
underlying testimonial reports that were not themselves admitted into evidence.” Id. at ___,
131 S. Ct. at 2722 (Sotomayor, J., concurring in part). Third, Bullcoming was not a case “in
which the State introduced only machine-generated results.” Id. at ___, 131 S. Ct. at 2722
(Sotomayor, J., concurring in part).
¶ 56 In Williams v. Illinois, 567 U.S. ___, 132 S. Ct. 2221 (2012) (plurality op.), the Court
considered whether the confrontation clause was violated by the admission of expert opinion
testimony from a forensic DNA analyst from the Illinois State Police regarding DNA analysis
performed by Cellmark. Justice Alito authored a plurality opinion, joined by Justices
Roberts, Kennedy, and Breyer. These four justices were the dissenters in Melendez-Diaz and
Bullcoming. The plurality concluded the expert’s testimony was not barred, because

-12-
 Cellmark’s report could be a basis for the expert’s opinion and the trial judge was presumed
to have considered it for that purpose, not the truth of the matter asserted. See Williams, 567
U.S. at ___, 132 S. Ct. at 2240 (plurality op.).
¶ 57 The Williams plurality also independently concluded the admission of the actual DNA
profile for its truth would not have violated the confrontation clause. Id. at ___, 132 S. Ct.
at 2242 (plurality op.). The plurality noted that in all but one of the post-Crawford cases
finding a confrontation violation, the abuses shared two characteristics: “(a) they involved
out-of-court statements having the primary purpose of accusing a targeted individual of
engaging in criminal conduct and (b) they involved formalized statements such as affidavits,
depositions, prior testimony, or confessions.” Id. at ___, 132 S. Ct. at 2242 (plurality op.).
In Davis v. Washington, 547 U.S. 813, 829-32 (2006), an informal statement elicited in the
course of the police interrogation was found to be testimonial in nature. However, in every
case, including Davis, the “statement at issue had the primary purpose of accusing a targeted
individual.” Williams, 567 U.S. at ___, 132 S. Ct. at 2243 (plurality op.). “Thus, the plurality
concluded in Williams that not all forensic reports offered by the State are testimonial
statements.” People v. Leach, 2012 IL 111534, ¶ 118.
¶ 58 Justice Thomas concurred in the judgment in Williams and “agree[d] with the plurality
that the disclosure of Cellmark’s out-of-court statements through the expert testimony ***
did not violate the Confrontation Clause.” Williams, 567 U.S. at ___, 132 S. Ct. at 2255
(Thomas, J., concurring in the judgment). He did not agree, however, with the plurality’s
rationale, instead reached his conclusion “solely because Cellmark’s statements lacked the
requisite ‘formality and solemnity’ to be considered ‘ “testimonial’ ” for purposes of the
Confrontation Clause.” Williams, 567 U.S. at ___, 132 S. Ct. at 2255 (Thomas, J., concurring
in the judgment) (citing Michigan v. Bryant, 562 U.S. ___, ___, 131 S. Ct. 1143, 1167 (2011)
(Thomas, J., concurring in the judgment)).
¶ 59 Justice Breyer authored a concurring opinion, writing he would have preferred
reargument to address broader questions regarding the general application of the
confrontation clause to crime laboratory reports and underlying technical statements.
Williams, 567 U.S. at ___, 132 S. Ct. at 2244-45 (Breyer, J., concurring). One of Justice
Breyer’s concerns is relevant to this appeal:
“[A]ssume that the admissibility of the initial laboratory report into trial had been directly
at issue. Who should the prosecution have had to call to testify? Only the analyst who
signed the report noting the match? What if the analyst who made the match knew
nothing about either the laboratory’s underlying procedures or the specific tests run in the
particular case? Should the prosecution then have had to call all potentially involved
laboratory technicians to testify? Six to twelve or more technicians could have been
involved. (See Appendix, infra, which lists typically relevant laboratory procedures.)
Some or all of the words spoken or written by each technician out of court might well
have constituted relevant statements offered for their truth and reasonably relied on by
a supervisor or analyst writing the laboratory report. Indeed, petitioner’s amici argue that
the technicians at each stage of the process should be subject to cross-examination.”
Williams, 567 U.S. at ___, 132 S. Ct. at 2246-47 (Breyer, J., concurring).

-13-
¶ 60 The dissenting opinion in Williams, authored by Justice Kagan, notes Breyer’s concern:
“He principally worries that *** a State will have to call to the witness stand ‘[s]ix to
twelve or more technicians’ who have worked on a report. See ante, at 2247; see also
ante, at 2245-2246, 2253-2255. But none of our cases–including this one–has presented
the question of how many analysts must testify about a given report. (That may suggest
that in most cases a lead analyst is readily identifiable.) The problem in the cases–again,
including this one–is that no analyst came forward to testify. In the event that some future
case presents the multiple-technician issue, the Court can focus on ‘the broader “limits”
question’ that troubles Justice BREYER, ante, at 2248. But the mere existence of that
question is no reason to wrongly decide the case before us–which, it bears repeating,
involved the testimony of not twelve or six or three or one, but zero Cellmark analysts.”
(Emphasis omitted.) Williams, 567 U.S. at ___ n.4, 132 S. Ct. at 2273 n.4 (Kagan, J.,
dissenting, joined by Scalia, Ginsburg and Sotomayor, JJ.).
¶ 61 Elsewhere, in arguing the case is controlled by precedent, the Williams dissent asserts:
“ ‘[W]hen the State elected to introduce’ the substance of Cellmark’s report into
evidence, the analyst who generated that report ‘became a witness’ whom Williams ‘had
the right to confront.’ ” Williams, 567 U.S. at ___, 132 S. Ct. at 2268 (Kagan, J.,
dissenting, joined by Scalia, Ginsburg and Sotomayor, JJ.) (quoting Bullcoming, 564
U.S. at ___, 131 S. Ct. at 2716).
According to the dissent, under the Court’s prior analysis, “the substance of the report could
come into evidence only if Williams had a chance to cross-examine the responsible analyst.”
Williams, 567 U.S. at ___, 132 S. Ct. at 2267 (Kagan, J., dissenting, joined by Scalia,
Ginsburg and Sotomayor, JJ.). The dissent also criticized the majority’s formulation in
examining the purpose for which the statement was made, noting Melendez-Diaz and
Bullcoming merely asked whether the statement was made for the purpose of providing
evidence. Williams, 567 U.S. at ___, 132 S. Ct. at 2273-74 (Kagan, J., dissenting, joined by
Scalia, Ginsburg and Sotomayor, JJ.).
¶ 62 The State argues Williams is controlling in this case. Defendant argues Williams is
distinguishable because that case involved a bench trial, whereas this case is an appeal from
a jury trial. Defendant also argues the fractured opinion in Williams is not controlling on the
law and urges this court to rule in his favor based on Melendez-Diaz and Bullcoming.
¶ 63 Neither party is entirely correct. Granted, the first portion of the Williams plurality
opinion does distinguish between bench trials and jury trials. For example, the Williams
plurality notes the rules of evidence in federal and Illinois courts typically bar admission of
the facts and data underlying expert opinions in jury trials. Williams, 567 U.S. at ___, 132
S. Ct. at 2234-35 (plurality op.). The plurality also acknowledges the dissent “would have
force” in the context of a jury trial, where, “[a]bsent an evaluation of the risk of juror
confusion and careful jury instructions, the testimony could not have gone to the jury.”
Williams, 567 U.S. at ___, 132 S. Ct. at 2236 (plurality op.). In contrast, in a bench trial, it
is presumed the trial judge, as the trier of fact, understood the contested portions of the expert
testimony were not admissible to prove the truth of the matter asserted. Williams, 567 U.S.
at ___, 132 S. Ct. at 2236-37 (plurality op.).

-14-
¶ 64 Nevertheless, the second, independent portion of the Williams plurality opinion does not
depend on the difference between a bench trial and a jury trial. Rather, as the Illinois
Supreme Court notes in Leach (which involved the application of Williams to the
admissibility of an autopsy report), the second, independent portion of Williams establishes
that not all forensic reports offered by the State are testimonial. See Leach, 2012 IL 111534,
¶ 118. This was also Justice Thomas’s conclusion, although he disagreed with the plurality
regarding the reason Cellmark’s report was not testimonial. Williams, 567 U.S. at ___, 132
S. Ct. at 2255 (Thomas, J., concurring in the judgment). Accordingly, assuming, arguendo,
that Quartaro’s testimony was based in part on out-of-court statements, there would still be
no violation of the confrontation clause. See People v. Negron, 2012 IL App (1st) 101194,
¶ 48 (“We glean the central holding of Williams from the narrow grounds on which Justice
Thomas agreed with the plurality.”).4
¶ 65 Moreover, our conclusion would be the same absent Williams. The testifying expert in
this case is a Cellmark supervisor. Defendant argues the State was required to present
testimony from the technician who loaded the DNA samples onto the robotic instrumentation
and oversaw the testing in the wet chemistry lab. Thus, this case involves the question
adverted to but not technically before the Williams Court regarding the number of analysts
the State must call to satisfy the confrontation clause.
¶ 66 Even prior to the Supreme Court’s decision in Williams, this court expressed skepticism
of the idea the confrontation clause “would require each and every individual involved in the
testing and analysis of DNA to testify at trial,” where the testifying expert was a Cellmark
representative who performed an independent review of the analysts’ work. Johnson, 406 Ill.
App. 3d at 818 (dicta).5 Post-Williams, we find State v. Lopez, 45 A.3d 1 (R.I. 2012),
persuasive on this issue. In Lopez, “Matthew Quartaro, a supervisor at Cellmark, testified as
an expert witness on behalf of the state regarding the results of the DNA testing.” Lopez, 45
A.3d at 10. At trial:
“Quartaro testified that he did not personally observe the analysts who conducted the
cutting, extraction, or quantification, nor did he perform those steps. In fact, Quartaro
indicated that he never physically touched the evidence in this case. Despite this, he
testified that he had been ‘involved in the entire process’ by other means. Specifically,

4
In his reply brief and a motion to cite supplemental authority, defendant cites cases from
other states and federal courts discounting the Williams plurality opinion and relying on Melendez-
Diaz and Bullcoming. In light of Leach and Negron, we find the authorities defendant cites
unpersuasive.
5
The Johnson court ruled the testimony admissible on the ground it was not introduced to
prove the truth of Cellmark’s findings. Johnson, 406 Ill. App. 3d at 818. Subsequently, a majority
of the United States Supreme Court indicated a likely disagreement with that particular conclusion.
Williams, 567 U.S. at ___, 132 S. Ct. at 2256 (Thomas, J., concurring in the judgment); id. at ___,
132 S. Ct. at 2268 (Kagan, J., dissenting, joined by Scalia, Ginsburg and Sotomayor, JJ.). However,
as noted earlier, the issue of the number of analysts constitutionally required to testify in a case like
this one was not squarely at issue in Williams.

-15-
 Quartaro explained that he ‘evaluate[d] all the profiles, ma[d]e sure that *** the best
possible profile [s] [were obtained] from the evidence[,] *** compared all the profiles,
drew conclusions on those, calculate[d] statistics, [and] prepared [a] report.’ The only
portion of Quartaro’s report admitted into evidence was an allele table, which presented
the numerical-DNA profile of each of the seven samples tested. Quartaro testified that
he prepared this chart based on his analysis of computer-generated graphs, which
consisted of ‘raw data’ obtained from the PCR-testing stage. Quartaro’s report and
conclusions then were reviewed by another analyst at Cellmark, Kelli Byrd.” Id. at 10-11.
In Lopez, as in this case, the defendant argued such testimony violated his sixth amendment
right to confront the analysts who conducted the preliminary stages of the DNA testing. The
Supreme Court of Rhode Island distinguished the case from Bullcoming on the basis
Quartaro did not act as a surrogate witness because he was “integrally involved” in the
process of the DNA testing. Id. at 13. Acting as a Cellmark supervisor, he directed the DNA
testing, reviewed the case file, ensured the proper protocols were observed, personally
reviewed and analyzed the raw data and articulated his own conclusions. Id. at 13
¶ 67 The Lopez court acknowledged cross-examination of Quartaro did not necessarily address
every possibility of bias or error in the DNA testing. Id. at 16. Nevertheless:
“[t]he Supreme Court made it clear that the Confrontation Clause does not mandate ‘that
anyone whose testimony may be relevant in establishing the chain of custody,
authenticity of the sample, or accuracy of the testing device, must appear in person as
part of the prosecution’s case.’ ” Id. (quoting Melendez-Diaz, 557 U.S. at 311 n.1).
Accordingly, the Lopez court concluded the fact that Quartaro used data from the work of his
analysts “did not bestow upon defendant the constitutional right to confront each and every
one of those subordinate analysts.” Id. The court held:
“[W]here defendant had ample opportunity to confront Quartaro–the witness who
undertook the critical stage of the DNA analysis, supervised over and had personal
knowledge of the protocols and process of all stages involved in the DNA testing,
reviewed the notes and data produced by all previous analysts, and testified to the
controls employed by the testing lab to safeguard against the possibility of testing
errors–the Confrontation Clause was satisfied.” Id.
Other courts similarly reject the argument that the confrontation clause requires testimony
from every person involved in performing a forensic DNA analysis. E.g., Aguilar v.
Commonwealth, 699 S.E.2d 215, 222 (Va. 2010); Vann v. State, 229 P.3d 197, 210-11
(Alaska Ct. App. 2010); United States v. Boyd, 686 F. Supp. 2d 382, 385 (S.D.N.Y. 2010),
aff’d, 401 F. App’x 565 (2d Cir. 2010).
¶ 68 In this case, Quartaro was more involved in the DNA testing process than the expert in
Lopez, as he took the cuttings to send to DNA testing in the first instance. Moreover, similar
to Lopez, Quartaro independently reviewed the data and documentation in this case,
performed the analysis on the data, and authored the report for Cellmark. Furthermore,
Quartaro described the controls Cellmark used and testified the proper controls were run in
this case to ensure the instruments were functioning properly. Indeed, in this case Quartaro
testified the chain of custody was maintained as to all of the samples. What remains are

-16-
 potential questions regarding the authenticity of the sample, which normally goes to the
weight of the evidence rather than its admissibility. See Melendez-Diaz, 557 U.S. at 311 n.1.
Accordingly, even assuming, arguendo, that Williams was not applicable to this case,
defendant’s argument fails.
¶ 69 Defendant raises two related subissues in passing in his brief. First, defendant complains
in a single sentence, without citation to authority, that the State introduced a chart illustrating
the results of Cellmark’s testing. The record on appeal indicates the exhibit at issue was used
during testimony of Tomek, not Quartaro. The transcript of Tomek’s testimony indicates
defense counsel raised “no objection” to the use of the chart. The record on appeal contains
no written response to the State’s motion in limine to admit Quartaro’s testimony; the
transcript of the hearing on the motion contains no objection referring to the chart. Tomek’s
use of the chart was not raised as a grounds for a new trial in defendant’s posttrial motion.
Accordingly, this issue is forfeited because defendant failed to raise it at trial or in his motion
for a new trial. People v. Woods, 214 Ill. 2d 455, 470 (2005); People v. Eastling, 386 Ill.
App. 3d 884, 887-88 (2008). Furthermore, in instances of forfeiture, it is defendant’s burden
to establish plain error and “when a defendant fails to present an argument on how either of
the two prongs of the plain-error doctrine is satisfied, he forfeits plain-error review.” People
v. Hillier, 237 Ill. 2d 539, 545-46 (2010). Indeed, our supreme court has admonished this
court to consider constitutional questions only where the case cannot be determined on other
grounds. People v. White, 2011 IL 109689, ¶ 148 (and cases cited therein). Thus, we decline
to relax the forfeiture rule in this case.6

6
The special concurrence takes exception with our discussion of defendant’s forfeiture of
these issues and suggests the majority has mischaracterized defendant’s comment about the
introduction of the chart of DNA test results. The special concurrence alludes to two paragraphs of
defendant’s brief, in which the chart is mentioned precisely once, in passing, in a single sentence on
page 18 of the brief. That sentence states, “As in Bullcoming, merely presenting the testimony of
Quartaro and a chart showing results of the DNA testing, and not the actual Cellmark analyst who
performed the testing, failed to provide the defense the required opportunity to ‘ expose *** lapses
or lies on [the analyst’s] part.’ ”
The special concurrence asserts the exhibit at issue related to the testimony from both
Tomek and Quartaro, but the record indicates the chart was used by Tomek. The issue of the
introduction and use of the chart is a complex and significantly different question from the issue of
Quartaro’s testimony in general. Compare Lopez, 45 A.3d at 12-16, with id. at 16-20. In this case,
an analysis of the issue would be further complicated by the fact the chart was used by Tomek, not
Quartaro. The issues raised by Tomek’s testimony relying on Cellmark’s work is not necessarily
identical to the issues raise by Quartaro’s testimony regarding the work performed by Quaratro and
his subordinates. The two paragraphs from defendant’s brief which the special concurrence refers
to do not address these issues. The special concurrence suggests the burden was on the State to argue
the chart raises different issues. We disagree, as defendant mentions the chart in one sentence and
defendant’s legal authority does not address the issues raised by the chart.
Moreover, defendant did not object to the admission of the chart at trial or in his posttrial
motion. As our supreme court instructs us, one of the most important functions of the appellate court
is to determine whether an issue has been forfeited, so as to avoid unnecessary expenditure of

-17-
¶ 70 Second, defendant maintains Quartaro improperly bolstered his testimony by
volunteering on cross-examination, in response to the question of whether Bird merely
summarized what transpired at Cellmark regarding this case, that Bird reviewed his report
and agreed with its conclusion. Similar to defendant’s first passing objection, the trial
transcript indicates defense counsel did not object to the testimony or move to strike it.
Defendant raised the issue of Quartaro’s testimony about aspects of the DNA testing process
in his posttrial motion, but did not specifically challenge his testimony about Bird on either
constitutional or ordinary evidentiary grounds. In general, “a defendant must both specifically
object at trial and raise the specific issue again in a posttrial motion to preserve any alleged
error for review.” Woods, 214 Ill. 2d at 470. In addition, defendant did not request plain-error
review, thereby forfeiting it. Hillier, 237 Ill. 2d at 545-46. Thus, for the reasons already
stated, we decline to relax the rule of forfeiture. See White, 2011 IL 109689, ¶ 148.

¶ 71 CONCLUSION
¶ 72 In sum, we conclude the trial court did not abuse its discretion in admitting “other
crimes” evidence in this case. We also conclude defendant failed to show the admission of
Quartaro’s testimony violated his sixth amendment right to confront the witnesses against
him, because the confrontation clause did not require the State to produce other Cellmark
technicians to testify regarding the preliminary steps in the DNA analysis prepared by
Quartaro. Defendant forfeited his other objections to the expert testimony in this case. For
all of the aforementioned reasons, the judgment of the circuit court of Cook County is
affirmed.

¶ 73 Affirmed.

¶ 74 JUSTICE GORDON, specially concurring.
¶ 75 I agree with the majority’s disposition of the case, but write separately to clarify three
points.
¶ 76 First, in paragraphs 69 and 70, the majority states that defendant waived consideration
of two “subissues” by not requesting plain-error review. However, although the State
discussed generally the larger confrontation clause issue, it did not assert in its appellate brief
that defendant forfeited these issues by failing to raise them in the trial court or in a posttrial

judicial resources. People v. Smith, 228 Ill. 2d 95, 106 (2008). Therefore, this court should not
refrain or deviate from fulfilling this function as set forth by our supreme court simply because the
State fails to mention the issue. Indeed, our supreme court has “repeatedly cited the general principle
that courts will address constitutional issues only as a last resort, relying whenever possible on
nonconstitutional grounds to decide cases.” People v. Jackson, 2013 IL 113986, ¶ 14 (and cases cited
therein). In this case, the complex and unsettled constitutional issue regarding the chart need not be
addressed, given our long-established and uncontroversial rules of forfeiture.

-18-
 motion, and thus, the State forfeited its right to claim waiver on this ground. People v. De
La Paz, 204 Ill. 2d 426, 433 (2003) (“It is well established that the State may waive
waiver.”); People v. Lacy, 407 Ill. App. 3d 442, 461 (2011).
¶ 77 For example, in People v. Hillier, 237 Ill. 2d 539, 546 (2010), the defendant argued to
our supreme court “that the State forfeited its forfeiture argument by failing to raise it in the
appellate court.” In response, the State “filed copies of the appellate court briefs with [our
supreme] court to establish that it did indeed argue forfeiture in the appellate court.” Hillier,
237 Ill. 2d at 546 n.3. The defendant then conceded this point at the oral argument before our
supreme court. Hillier, 237 Ill. 2d at 546 n.3. Since the State had, in fact, raised the issue of
forfeiture in its appellate brief, our supreme court held that the defense had failed to meet its
burden of establishing plain error by failing to argue it in its subsequent brief. Hillier, 237
Ill. 2d at 545-46.
¶ 78 In contrast to Hillier, the State in the case at bar did, in fact, forfeit forfeiture by failing
to argue in its appellate brief that defendant had failed to assert these issues either in the trial
court or in a posttrial motion. As a result, the majority should have addressed these issues
under a harmless-error review in its analysis. However, since I believe that the outcome
would be the same under either harmless-error or plain-error review, I specially concur.
¶ 79 The majority writes: “The special concurrence suggests the burden was on the State to
argue the chart raises different issues.” Supra ¶ 69 n.6. I do not understand this sentence in
the context of my special concurrence. What I have stated, quite simply, is that the State
waived the issue of forfeiture.
¶ 80 Second, the majority writes: “defendant complains in a single sentence, without citation
to authority, that the State introduced a chart illustrating the results of Cellmark’s testing.”
Supra ¶ 69. This statement is factually incorrect. Defendant’s brief contains a two-paragraph,
full-page discussion concerning the chart, including a discussion of the United States
Supreme Court’s decision in Bullcoming v. New Mexico, 564 U.S. ___, 131 S. Ct. 2705
(2011). The first sentence of the first paragraph is a thesis sentence, introducing defendant’s
discussion of how “the chart” and Quartaro’s testimony raised the same issues “[a]s in
Bullcoming.” The first sentence, or thesis sentence, of the second paragraph continues this
discussion referring back to “the DNA evidence,” which includes the DNA evidence named
in the immediately preceding paragraph: the chart and Quartaro’s testimony. Thus, any
suggestion that defendant forfeited this claim by failing to provide reasoned legal argument
or citation to relevant authority would be incorrect and misplaced. Supra ¶ 69 n.6.
¶ 81 The majority asserts that the chart relates only to Tomek’s testimony but not to
Quartaro’s testimony. Supra ¶ 69 n.6. It relates to both. At trial, Quataro testified that he
supervised a team of eight DNA analysts at the Cellmark laboratory and that he authored
Cellmark’s report. However, he admitted that he did not oversee the tests used in this case.
Then Tomek, who is employed by the Illinois State Police, used the chart, which illustrated
the results of tests done by both Cellmark and the Illinois State Police crime lab, in order to
offer his opinion that defendant’s DNA profile matched the DNA profile generated by the
Cellmark lab. Quartaro’s testimony laid the foundation for the information in the chart that
defendant now challenges on appeal. Thus, on the facts and arguments made before us, the

 issues related to the chart are not significantly different from the issues related to Quartaro’s
testimony.
¶ 82 The majority cites State v. Lopez, 45 A.3d 1, 12-16 (R.I. 2012), for the proposition that
the “use of the chart is a complex and significantly different question from the issue of
Quartaro’s testimony in general.” Supra ¶ 69 n.6. In Lopez, the Rhode Island Supreme Court
considered whether an allele table contained “mere machine-generated” data and was thus
nontestimonial. Lopez, 45 A.3d at 17. In the case at bar, the State has not raised this
argument and thus, it is not before us.
¶ 83 In addition, I specially concur on another issue that I believe the majority handled
improperly. The State argues to this court in its appellate brief that defendant’s confrontation
rights were fully satisfied by his opportunity to cross-examine the DNA supervisor, and cites
in support Bullcoming v. New Mexico, 564 U.S. ___, 131 S. Ct. 2705 (2011). I agree.
¶ 84 On appeal, defendant does not suggest any questions that he would have asked the
nontestifying DNA analysts and that he could not have asked their supervisor. By contrast,
the United States Supreme Court found a confrontation clause violation in Bullcoming v.
New Mexico, 564 U.S. ___, ___, 131 S. Ct. 2705, 2715 (2011), stating: “Significant here,
Razatos had no knowledge of the reason why Caylor had been placed on unpaid leave. With
Caylor on the stand, Bullcoming’s counsel could have asked questions designed to reveal
whether incompetence, evasiveness, or dishonesty accounted for Caylor’s removal from his
work station.” By contrast, in the case at bar, defendant does not identify any questions that
he could not pose to the supervisor and that only the analysts could answer. The majority
does not discuss this issue in its decision.
¶ 85 For the foregoing reasons, I specially concur.
