 OPINION

¶1 Fifteen-year-old Sebastian Rodriguez was charged with first degree murder in connection
with the shooting of thirteen-year-old Sameere Conn on October 1, 2008. At the time of the
offense, 15-year-olds charged with first degree murder were automatically excluded from
juvenile court jurisdiction. Sebastian was accordingly tried, convicted, and sentenced as an
adult. Following his jury trial, the circuit court sentenced Sebastian to 50 years in prison: 25
years for the murder and 25 additional years pursuant to a mandatory firearm enhancement. In
this direct appeal, Sebastian argues that (1) the circuit court erroneously denied his motion to
suppress evidence found during a search of his home, (2) expert testimony identifying a
revolver found in his home as the murder weapon was improperly admitted without a hearing
to determine if it was based on generally accepted scientific methodologies, and (3) the
imposition of a 50-year sentence on an offender who was 15 years old at the time of his offense
is unconstitutional.
¶2 Shortly after Sebastian filed his notice of appeal, the Illinois legislature raised the age of
automatic transfer from juvenile court to criminal court for an individual charged with first
degree murder from 15 to 16 years of age and adopted additional sentencing guidelines for
defendants who were under the age of 18 at the time of their offenses, including making
firearm enhancements discretionary, rather than mandatory, for such individuals. In
supplemental briefing, Sebastian argues that these amendments should apply to his case.
¶3 For the reasons that follow, we affirm Sebastian’s conviction for first degree murder,
vacate his sentence, and remand this matter to the juvenile court.

¶4 BACKGROUND
¶5 A. Pretrial Proceedings
¶6 Nine days after Sameere Conn’s death, Chicago police obtained a warrant to search
Sebastian Rodriguez’s home for evidence related to the shooting. In the complaint for the
search warrant, Detective Ricky Bean identified two eyewitnesses who testified before a grand
jury that they knew Sebastian and saw him, dressed in a hooded sweatshirt, fire shots into the
convenience store where Sameere was killed, as well as a third eyewitness who identified
Sebastian as the individual he saw looking through the glass window of the store’s door just
before shots were fired through that window. According to the complaint, officers also learned
from two other witnesses that Sebastian was known to possess a “kill list” of potential victims
that included Sameere. Finally, the complaint alleged that, in connection with prior arrests,
Sebastian had given the address 10744 South Hoxie Avenue in Chicago as his home address.
¶7 Finding this sufficient to establish probable cause, the circuit court issued a warrant to
search Sebastian’s home for “[o]ne dark colored or grey hooded sweat shirt, [o]ne document
containing a list of individual names, [a]nd one handgun.” Officers executed the warrant on
October 11, 2008, retrieving a revolver from under a floorboard in the bathroom and a number
of hooded sweatshirts from elsewhere in the home.
¶8 Sebastian was charged by grand jury indictment with first degree murder.
¶9 In his motion to suppress filed on April 26, 2010, Sebastian argued that evidence recovered
during the October 11, 2008, search should be excluded because, even if officers had probable

-2-
 cause to arrest him, they had no reason to believe that specific evidence would be found in his
home 10 days after the shooting.
¶ 10 Although an evidentiary hearing was held on Sebastian’s motion to suppress, the testimony
offered related only to the scope of the search and the manner in which it was conducted, issues
that are not raised in this appeal. The circuit court denied Sebastian’s motion, explaining that,
in its view, when officers have “a strong identification of a suspected shooter and that person’s
home,” then “it is not beyond logic, nor *** beyond the law, to have probable cause to see if in
that person’s place of residence, the place they call home, the place in which they keep their
items, that there might be evidence of the crime there.”
¶ 11 On May 9, 2013, Sebastian moved for an evidentiary hearing, pursuant to Frye v. United
States, 293 F. 1013 (D.C. Cir. 1923), on the admissibility of expert testimony he expected the
State to introduce linking the gun found in his home to a bullet recovered from the scene of the
crime. Although he acknowledged that such testimony had historically been admitted by
courts, he insisted a Frye hearing was needed because the reliability of the methodologies
employed by ballistics experts had recently been questioned in the scientific community.
¶ 12 The circuit court disagreed and denied Sebastian’s motion. Noting that it was aware of no
published opinion of any court concluding that firearm identification evidence was not
generally accepted in the scientific community, the court concluded that Sebastian’s concerns
went to the weight and not to the admissibility of the evidence.

¶ 13 B. Trial
¶ 14 A four-day trial in this case began on February 4, 2014. Because Sebastian does not contest
the sufficiency of the evidence to support his conviction, we include only a brief summary of
the trial testimony, with a fuller recitation of the firearms identification testimony, to provide
context for the evidentiary issues raised on appeal.
¶ 15 At approximately 8 p.m. on October 1, 2008, Sameere walked home from nearby Trumball
Park after a football game with a group of his friends from school. Sameere and two other boys
stopped to purchase snacks at Hook’s Finer Foods, a convenience store located at 106th Street
and Bensley Avenue in Chicago, while two other friends waited outside. A handful of people
were in the store at the time: the cashier, the owner of the building, and a few customers,
including an individual known as “Tone” or “Tony,” who was known to frequent the store.
Sameere was near the front of the store waiting to make his purchase when, according to
witnesses, he was shot multiple times through a window in the front door of the store.
¶ 16 Joseph Neal and John Rodgers testified that, on the evening of October 1, 2008, they were
waiting across the street from Hook’s Finer Foods for Sameere and the others when they saw
Sebastian, who they knew and regularly saw around the neighborhood, approach the store.
According to Joseph and John, Sebastian looked at them, put the hood of his sweatshirt up, and
started firing a gun into the store. At trial, both boys insisted that Sebastian’s sweatshirt was
red—Joseph said “[i]t was red, same red as he always had”—and denied previously telling
officers and a grand jury that it was blue and gray. Joseph also denied telling the grand jury that
he and John were standing farther away from the store, near some offices. However, Joseph
acknowledged that he initially told officers and a television reporter that he was inside the store
and saw Sebastian tap on the glass before shooting. When asked why he lied, Joseph explained
that he thought the better vantage point would make him more believable: “I knew who I seen
and I really wanted [Sebastian] to get got for what he did, that’s why I said all of that.”

-3-
¶ 17 Anthony Ray (also known as “Tone” or “Tony”), who was in custody for failing to appear
as a witness in this case, acknowledged his previous convictions for stealing a car and for
selling drugs and that he was a diagnosed schizophrenic who took medication for that
condition. Anthony testified that he was at Hook’s Finer Foods just before 8 p.m. on the
evening of October 1, 2008, and saw a light-skinned person wearing “a black hoody” standing
outside just before shots were fired through the front door of the store. Although Anthony at
first told officers that he did not see the shooter, he identified a photo of Sebastian for police
officers several days later, writing on the photo, “I saw him shoot through the window.
Positive.” However, at trial Anthony indicated that his identification was influenced by “two
young kids” who were also in the store at the time of the shooting and were taken to the police
station with him for questioning. Anthony explained: “I didn’t personally, personally, like
myself, describe that—the person that did the shooting ***. It’s kind of like, kind of like I put
two and two together. I seen a face and a hoody and everybody else saying they knew his name
and they knew everything that happened.”
¶ 18 The State called two friends of Sameere’s, Kiante Lilly and Mario Martinez, to describe
Sebastian’s statements and conduct prior to the shooting. Kiante testified that, at Sameere’s
request, he set up a three-way telephone call in late September to try to resolve “a dispute”
between Sameere and Sebastian. Although Kiante told the grand jury that, during that
conversation, Sebastian said he had a “death list” and told Sameere “[y]ou on there, too, boy,”
at trial Kiante denied such a list was ever discussed, characterizing the call as nothing more
than “a friendly conversation.” Mario testified that Sebastian got out of a green truck and
approached Mario on the evening of October 1, 2008, asked Mario if he wanted “to go take a
ride,” and showed him a gun—a revolver, “I don’t really know, like a .38”—that Sebastian had
wrapped in a sweater. Mario declined and went inside. Although Mario heard shots soon after,
he did not learn that Sameere had been killed until the next morning and did not tell officers
about his encounter with Sebastian until they sought him out for an interview 10 days later.
¶ 19 The physical evidence in this case consisted of (1) a medium caliber lead bullet fragment
recovered from Sameere’s body; (2) a fired bullet recovered from a shelf inside Hook’s Finer
Foods on October 1, 2008; (3) a gunshot residue collection kit consisting of swabs of each of
Sebastian’s hands plus a control swab, which was administered by police officers shortly after
midnight on October 2, 2008; (4) a blue steel .357 Dan Wesson revolver containing six
.357-magnum caliber unfired cartridge cases, retrieved from under the floorboards of the
bathroom during the October 11, 2008, search of the home at 10744 South Hoxie Avenue in
Chicago; and (5) two gray and five black “hoody jackets” also recovered during that search.
¶ 20 Brian Mayland, a pattern evidence program manager for the Illinois State Police forensic
sciences command, testified as an expert in the field of toolmark and firearm identification.
Mr. Mayland previously worked for 17 years as a forensic scientist in firearms and toolmark
identification and, for just over one year, as a laboratory director. Although his undergraduate
degree was in business, Mr. Mayland testified that he had completed specialized training in the
field of firearms identification, including a two-year training program conducted by the Illinois
State Police, and had testified as an expert in the field approximately 80 times.
¶ 21 Mr. Mayland explained that a cartridge consists of four basic components: the case; the
powder inside the case; the bullet, which is seated inside of the case; and the primer, a
pressure-sensitive chemical compound located in the head of the case. When a gun is fired, the
primer is struck, the resulting spark ignites the powder, gasses from the burning powder create

-4-
 pressure, and the pressure forces the bullet from the mouth of the cartridge down the barrel
where rifling—raised and lowered areas known as “lands” and “grooves”—form a twisting
pattern along the inside of the barrel that causes the bullet to spin. Mr. Mayland testified that,
as a firearm analyst, he uses a comparison microscope to examine two bullets or cartridge
cases and compare the marks that are left behind on those items as a result of the firing process.
Certain identifying features—like the caliber of the bullet, the number and width of the
grooves in the rifling, and the direction of the twist—are known as “class characteristics”; they
are present at the time of manufacture and common to an entire class of firearms. Other marks
are created by imperfections that develop in a gun over time, as it is fired, and can be unique to
a particular gun.
¶ 22 In this case, Mr. Mayland examined the fired bullet recovered from the scene of the crime
and determined that it was a .38-caliber bullet jacket with six lands, six grooves, and a
right-hand twist. He concluded that the metal fragment recovered from Sameere’s body was
too mutilated to be suitable for comparison. Mr. Mayland then test fired the revolver recovered
from Sebastian’s house, shooting four bullets into a tank of water, which slows the bullets
without damaging them. He compared the test shots to each other to determine if he “could
identify test shot with test shot,” something he acknowledged is not always possible. In this
case he determined that it was. He then compared the test shots side by side with the fired
bullet under a comparison microscope. It was Mr. Mayland’s opinion “that the fired bullet
jacket was fired in that firearm.”
¶ 23 Defense counsel objected to Mr. Mayland providing this conclusion without elaborating on
the specific similarities or differences between the compared specimens that he relied upon as
the basis for his opinion. The court sustained the objection, pending further inquiry. When
asked to elaborate, Mr. Mayland stated that he “saw a sufficiently similar pattern of individual
characteristics that allowed [him] to form an opinion.” Specifically, “[t]here were striated
marks that lined up when [he] was doing the comparison from the evidence bullet to the test
fired bullet.” Defense counsel again objected, but this time the trial court overruled the
objection.
¶ 24 On cross-examination, Mr. Mayland acknowledged that six is the most common number of
lands and grooves and it is “very common” for a revolver to have six lands and grooves with a
right-hand twist. Based on Mr. Mayland’s experience, he believed that hundreds of guns in
Chicago could have those same characteristics, noting, however, that he could not be more
specific because gun manufacturers “are very close” with such information.
¶ 25 Mr. Mayland also noted that the bullet jacket he analyzed was “badly mutilated,”
consistent with it having struck something. “Based on the condition of the bullet jacket,” he
said he measured at least two and “probably three” lands and grooves, although he did not
know that for certain and did not document his measurements in his notes. Mr. Mayland
acknowledged that none of the test shots matched the fired bullet casing exactly. However, he
also stated that “no two test shots will ever look exactly the same.” Mr. Mayland insisted that,
in this case, “there was a sufficiently similar pattern” between the test shots and the fired bullet
case for him to form his opinion. Mr. Mayland agreed both that there is no nationally
recognized standard to determine that the patterns were close enough to have been generated
by the same gun and that his opinion was a subjective one, not capable of verification by
objective testing.

-5-
¶ 26 On redirect examination, Mr. Mayland reiterated that he has compared tens of thousands of
bullets and cartridge cases over his career, that he followed all Illinois State Police lab
protocols, and that he used methods commonly accepted in the field of firearms identification.
Mr. Mayland confirmed that nothing he was asked during cross-examination affected his
opinion that the bullet he analyzed was fired from the revolver found in Sebastian’s home.
¶ 27 Mary Wong, a forensic scientist with the Illinois State Police forensic sciences division,
testified as an expert in the field of gunshot residue analysis. Ms. Wong tested the swabs from
the residue collection kit administered to Sebastian and the hooded sweatshirts retrieved from
his home. None of the items tested positive for gunshot residue. Although Ms. Wong found
two “tricomponent particles” on the sample taken from Sebastian’s left hand and one on the
sample taken from his right hand, she explained that at least three particles from the same
sample are required to make a positive identification. All Ms. Wong could conclude from her
analysis was that Sebastian “may not have discharged the firearm with either hand” and, “if he
did, then the particles were either removed by activity or not deposited or not detected by the
procedure.” Although tricomponent particles are found in fireworks and car airbags in addition
to gunshot residue, Ms. Wong stated that other particles one would expect to find following
contact with those items were not present in the samples she tested. However, she
acknowledged that gunshot residue particles may be transferred to a person who touches a
surface in a room where a gun was fired or who comes in contact with someone who recently
fired a gun.
¶ 28 Sebastian did not testify but presented the testimony of several witnesses.
¶ 29 Rosa Silva, an investigator with the public defender’s office, testified that, in 2013, Joseph
Neal told her that on the night of October 1, 2008, he saw a person with a red hoody sweatshirt
but that it was dark and he could see only the skin on the left side of the person’s jaw. Joseph
told Ms. Silva he thought the person was Sebastian because of the hooded sweatshirt.
¶ 30 Sebastian’s father, Steven Rodriguez, Sr., testified that in October 2008 he owned a green
Dodge Dakota and lived at 10744 South Hoxie Avenue in Chicago with his five sons. Mr.
Rodriguez’s two oldest sons, Steven Jr. and David, who were, respectively, 21 and 20 years
old, were members of the Latin Counts gang and had their friends over to the house “[a]ll the
time.”
¶ 31 Steven Rodriguez, Jr., testified that Sebastian came home alone after school on October 1,
2008, and remained in his room until police officers arrived around 8:15 p.m. On
cross-examination, Steven acknowledged that he was in the front of the house watching TV
and playing video games and was not looking at the back door. Steven did not ever tell the
police that Sebastian had been at home with him because he did not think they would believe
him.
¶ 32 Frank Maizer testified that he owned the building where Hook’s Finer Foods is located and
was in the store on the night of October 1, 2008. According to Mr. Maizer, the store had four
surveillance cameras, but they were not recording that day because the memory was full. He
denied telling officers that he had inadvertently erased the videos but agreed that he might have
told them that Anthony Ray removed an object from his mouth before the police arrived.
¶ 33 In its closing argument, the State urged the jury to believe the eyewitness testimony
identifying Sebastian as the shooter, which was corroborated by the particles of gunshot
residue found on Sebastian’s hands and Mr. Mayland’s testimony that the gun found in
Sebastian’s home was the murder weapon. Defense counsel responded by pointing out that

-6-
 there were innocent explanations for a few particles of gunshot residue to be on a person’s
hands and attacked Mr. Mayland’s conclusions as not being based on objective standards or
specific measurements. Defense counsel argued that, following the shooting, Sameere’s
friends heard a rumor that Sebastian killed Sameere and were willing to lie about what they
saw to make sure he was convicted. According to defense counsel, it was more likely that some
unidentified shooter intending to shoot Anthony Ray, a former gang member who was carrying
drugs at the time, had inadvertently shot Sameere.
¶ 34 The jury found Sebastian guilty of first degree murder, and the circuit court denied his
motion requesting a new trial, in which he argued that the circuit court erred when it denied
both his motion to suppress and his motion for a Frye hearing. Following a hearing, the court
sentenced Sebastian to 25 years in prison for first degree murder (730 ILCS 5/5-4.5-20(a)
(West 2014)), plus a mandatory sentencing enhancement of 25 additional years for personally
discharging the firearm that caused Sameere’s death (730 ILCS 5/5-8-1(a)(1)(d)(iii) (West
2014)), and 3 years of mandatory supervised release (730 ILCS 5/5-8-1(d)(1) (West 2014)).
The court denied Sebastian’s motion to reconsider his sentence, and Sebastian appealed.

¶ 35 JURISDICTION
¶ 36 Sebastian was sentenced by the circuit court on March 31, 2014, and timely filed his notice
of appeal on April 15, 2014. Accordingly, this court has jurisdiction pursuant to article VI,
section 6, of the Illinois Constitution (Ill. Const. 1970, art. VI, § 6) and Illinois Supreme Court
Rules 603 and 606, governing appeals from a final judgment of conviction in a criminal case
(Ill. S. Ct. Rs. 603, 606 (eff. Feb. 6, 2013)).

¶ 37 ANALYSIS
¶ 38 On appeal, Sebastian argues that his conviction for first degree murder should be reversed,
both because the circuit court erroneously denied his motion to suppress the evidence resulting
from the search of his residence for a lack of probable cause and because the circuit court
should have conducted a Frye hearing before admitting the testimony of the State’s expert on
toolmark and firearms identification.
¶ 39 Sebastian also challenges his sentence, arguing both that it was unconstitutional when it
was imposed and that an amendment to the exclusive jurisdiction statute changing the age from
15 to 16 for the automatic transfer to criminal court of cases involving certain crimes should be
applied retroactively to his case. Pursuant to that amendment, Sebastian asks us to vacate his
sentence and remand this matter to juvenile court, where the State may seek a discretionary
transfer hearing if it chooses. Sebastian alternatively argues that he is entitled to a new
sentencing hearing conducted pursuant to amended sentencing guidelines for individuals who
were under the age of 18 at the time of their offenses.
¶ 40 We address each argument in turn.

¶ 41 A. Motion to Suppress
¶ 42 Sebastian initially argues that the circuit court should have granted his motion to suppress
because the police lacked sufficient probable cause to search his home. Sebastian does not
argue that the police lacked probable cause to arrest him for Sameere’s murder, but that having
this did not necessarily mean they also had probable cause to search his home for specific

-7-
 evidence. According to Sebastian, the complaint submitted by Detective Bean in support of the
search warrant was defective because it failed to establish a sufficient nexus between
Sameere’s shooting and the items sought from Sebastian’s home 10 days later, i.e., the murder
weapon, a hooded sweatshirt worn during the shooting, and a suspected list of potential
victims. The State argues that, under the circumstances of this case, it was reasonable for the
circuit court to infer that such items might be found in Sebastian’s home.
¶ 43 Both the United States Constitution and the Illinois Constitution require that a warrant to
search an individual’s home must be based on probable cause and supported by an affidavit
describing the place to be searched and the items to be seized. U.S. Const., amend. IV; Ill.
Const. 1970, art. I, § 6. Probable cause exists “if facts set forth in an affidavit would cause a
reasonable person to believe a crime has been committed and evidence of that crime is in the
place to be searched.” People v. Damian, 299 Ill. App. 3d 489, 491 (1998). A nexus must be
established—directly or through reasonable inferences—between the criminal offense, the
items to be seized, and the place to be searched. People v. Beck, 306 Ill. App. 3d 172, 178-79
(1999). The issuing court’s task “is simply to make a practical, commonsense decision
whether, given all the circumstances set forth in the affidavit ***, there is a fair probability that
contraband or evidence of a crime will be found in a particular place.” (Internal quotation
marks omitted.) People v. McCarty, 223 Ill. 2d 109, 153 (2006). Although we review a circuit
court’s ruling on a motion to suppress de novo (People v. Pitman, 211 Ill. 2d 502, 512 (2004)),
we defer to an issuing judge’s determination of probable cause and resolve any doubts in favor
of upholding a warrant that has been issued (People v. Exline, 98 Ill. 2d 150, 156 (1983) (citing
United States v. Ventresca, 380 U.S. 102 (1965)).
¶ 44 We are satisfied that Detective Bean’s complaint established probable cause to search
Sebastian’s home. The police sought not only the murder weapon and a list of intended victims
but a specific article of clothing—a dark-colored or gray hooded sweatshirt—identified by
three eyewitnesses as something Sebastian was wearing at the time of the shooting. Although
we certainly agree that probable cause to arrest does not always equate to probable cause to
search the arrestee’s home, it is reasonable to infer, absent evidence to the contrary, that a
person will generally keep possessions, including possessions that link that person to the
crime, in his or her home. See, e.g., People v. Hammers, 35 Ill. App. 3d 498, 504 (1976) (“The
complaint was sufficient to show probable cause that [the] defendant shot and killed the victim,
and, if so, it was reasonable for the issuing judge to infer that the weapon used might be at the
defendant’s home nine days later.”); People v. Weinger, 63 Ill. App. 3d 171, 175 (1978)
(concluding that it was a “logical supposition” for the defendant to have clothing and jewelry
purportedly worn by him during the murders he was charged with, as well as the murder
weapon, in his apartment). Here, it was entirely reasonable to infer that Sebastian, a
15-year-old boy with no vehicle or other place to store such items, would keep a gun, clothing,
and a list of potential targets at his residence.
¶ 45 In the cases relied on by Sebastian, circumstances were present that undermined the
common, justified assumption that possessions are generally kept in the home. For example,
Sebastian relies on People v. McCoy, 135 Ill. App. 3d 1059 (1985), but the defendant in
McCoy, who was charged with possessing a firearm without a firearm owner’s identification
card, was an adult who was recently seen by a coworker with several guns in his van. Id. at
1062. Under these circumstances, where the defendant had other places available to him to
keep the guns at issue—i.e., at his place of employment or in his van—more was needed to say

-8-
 that a fair probability existed that the guns would be found in the defendant’s home. Id. at
1066.
¶ 46 People v. Rojas, 2013 IL App (1st) 113780, is similarly distinguishable. There, the only
evidence supporting a warrant to search the defendant’s residence consisted of cryptic
telephone conversations that, although they might have suggested “that the criminal activity of
drug trafficking was afoot,” did not indicate where the drug trafficking was occurring. Id. ¶ 18.
To the contrary, the conversations suggested that the other party did not know where the
defendant’s house was located and had not been there before. Id. Under those circumstances,
the court in Rojas concluded that the officers’ “generic offering that drug trafficking records
‘are often maintained under dominion and control of the narcotics traffickers, and as such, are
often kept in their residences or other secure locations’ ” did not rise above the level of
conjecture. Id. Like the defendant in McCoy, who had other places available to him to store the
firearms he was alleged to illegally possess, the defendant in Rojas could have stored such
records in other locations. The absence of any evidence indicating that Sebastian, a teenager
living in his father’s home, had other places available to him to store his possessions
distinguishes the facts of this case from those present in both McCoy and Rojas.
¶ 47 Because we conclude that probable cause existed to search Sebastian’s home, we need not
reach the State’s alternative arguments that the good faith exception to the exclusionary rule
applies or that the admission of evidence resulting from the search was harmless error.

¶ 48 B. Motion for a Frye Hearing
¶ 49 Sebastian also argues that the circuit court erred in denying his motion to either exclude the
State’s toolmark and firearm identification evidence or to hold a Frye hearing to determine the
admissibility of that evidence. In support of his contention, both in the circuit court and on
appeal, that such evidence is not generally accepted in the scientific community, Sebastian
relies primarily on a 2009 report authored by the National Research Council of the National
Academy of Sciences (NRC) entitled Strengthening Forensic Science in the United States: A
Path Forward.1 In that report, the NRC noted that toolmark identification has “never been
exposed to stringent scientific scrutiny,” 2 involves “subjective qualitative judgments by
examiners,”3 is “based on unarticulated standards,”4 and lacks any “statistical foundation for
estimation of error rates.”5 The NRC concluded that, although there is some benefit to be
derived from this testimony, additional studies are needed to address these concerns.
¶ 50 The circuit court denied Sebastian’s motion for a Frye hearing, concluding that the
criticisms raised in the NRC’s report go to the weight, and not the admissibility, of toolmark
and firearm identification evidence. The court also noted that there are no published opinions
holding that such evidence is not generally accepted in the relevant scientific community.

¶ 51 In Illinois, “new” or “novel” scientific evidence is only admissible if it meets the standard
set out in Frye v. United States, 293 F. 1013 (D.C. Cir. 1923). People v. McKown, 226 Ill. 2d
245, 254, 257 (2007). “[T]he methodology or scientific principle upon which the opinion is
based [must be] sufficiently established to have gained general acceptance in the particular
field in which it belongs.” (Internal quotation marks omitted.) Id. at 254. A court may
determine whether a methodology or principle is generally accepted either by conducting an
evidentiary hearing or “by taking judicial notice of unequivocal and undisputed prior judicial
decisions or technical writings on the subject.” Id. A scientific methodology need not be
universally accepted or even accepted by a majority of experts in the field; “[i]nstead, it is
sufficient that the underlying method used to generate an expert’s opinion is reasonably relied
upon by experts in the relevant field.” In re Commitment of Simons, 213 Ill. 2d 523, 530
(2004). Although it is within the circuit court’s discretion to decide both whether a particular
witness is qualified to testify as an expert in a particular field and whether the testimony that
witness will offer is relevant, we review de novo the circuit court’s determination of whether
the methodology used by the witness meets Frye’s “general acceptance” standard. People v.
Nelson, 235 Ill. 2d 386, 430-31 (2009).
¶ 52 We first consider whether toolmark and firearm identification evidence is “new” or
“novel.” The State contends that it is decidedly not, noting that courts have allowed such
evidence since at least 1930, when our supreme court held in People v. Fisher, 340 Ill. 216,
240-41 (1930), that, while a jury is not bound to accept it as true, firearm identification
evidence “is competent expert testimony on a subject properly one for expert knowledge.” In
the decades since Fisher, firearms experts have regularly testified in Illinois courts, for both
the prosecution and the defense.
¶ 53 Sebastian does not dispute this but insists that, pursuant to our supreme court’s analysis in
McKown, firearm identification evidence is nevertheless novel because “there is no record that
there has ever been a Frye hearing in Illinois to determine whether generally accepted
scientific principles support [it].” The court in McKown held that the horizontal gaze
nystagmus (HGN) test, a field sobriety test frequently used by police officers, was a novel
methodology subject to the Frye standard. McKown, 226 Ill. 2d at 258. The court explained
that its holding was based on “the history of legal challenges to the admissibility of HGN test
evidence, and the fact that a Frye hearing ha[d] never been held in Illinois.” Id. However, as
the court noted, the HGN test was “repeatedly challenged in court, with varying degrees of
success,” both in Illinois and in other states, and this court had issued “divergent opinions on
the topic,” such that the general acceptance of the test “remain[ed] unsettled.” (Internal
quotation marks omitted.) Id. at 257.
¶ 54 This case is distinguishable from McKown because the admissibility of firearms
identification evidence is not similarly “unsettled” in Illinois. The circuit court noted that it
was unaware of any published opinion of any court stating that firearms evidence was not
generally accepted in the scientific community, and Sebastian has cited none on appeal. The
few out-of-state cases Sebastian cites—in which courts have raised concerns about the
reliability of such evidence but have nonetheless held the methodology to be sufficiently
reliable to be admitted, at least in some qualified form—do not create the same situation the
McKown court was presented with, where legal challenges were resolved both for and against
admissibility of the HGN test and the law was truly unsettled. See United States v. Glynn, 578

 F. Supp. 2d 567, 569-75 (S.D.N.Y. 2008); United States v. Monteiro, 407 F. Supp. 2d 351, 355
(D. Mass. 2006); United States v. Green, 405 F. Supp. 2d 104, 120-24 (D. Mass. 2005).
¶ 55 Similarly unhelpful are cases involving testimony based on scientific methodologies that,
although sometimes deemed admissible, never achieved the same sort of widespread
acceptance as ballistics evidence. See People v. Zayas, 131 Ill. 2d 284, 296 (1989)
(hypnotically refreshed testimony); People v. Baynes, 88 Ill. 2d 225, 244 (1982) (polygraph
tests).
¶ 56 Although we understand the concerns raised by other courts and by the NCR in its report
regarding the subjectivity of firearm identification testimony and the inability to test its
accuracy, we cannot say that the circuit court erred in denying Sebastian’s motion for a Frye
hearing. Toolmark and firearm identification evidence is not new or novel, either pursuant to
the plain meaning of those words or in accordance with the analysis employed by our supreme
court in McKown. Far from being unsettled, the law in Illinois is consistent in its admission of
such evidence. See People v. Robinson, 2013 IL App (1st) 102476, ¶ 80.
¶ 57 Nor do we find that the NCR’s report so undermines the reliability of ballistics evidence
that it has ceased to be “generally accepted” in the scientific community. We agree with the
circuit court that the report’s concerns go to the weight and not to the admissibility of such
evidence. Indeed, our review of the record in this case indicates that—in connection with the
his objection that some of Mr. Mayland’s testimony lacked foundation, the denial of which
Sebastian chose not to contest on appeal—during cross-examination defense counsel explored
at length the limitations of Mr. Mayland’s conclusions.

¶ 58 C. Retroactivity of Legislative Amendment
¶ 59 Shortly after Sebastian filed his notice of appeal, Public Act 99-258 was enacted (Pub. Act
99-258 (eff. Jan. 1, 2016)). Among other things, it amended section 5-130 of the Juvenile
Court Act of 1987 to raise the age of automatic transfer from juvenile court to criminal court
for an individual charged with first degree murder from 15 to 16 years of age (705 ILCS
405/5-130(1)(a) (West Supp. 2015)); amended the Unified Code of Corrections to require
consideration of certain mitigating factors when sentencing individuals under the age of 18 in
criminal court (730 ILCS 5/5-4.5-105(a) (West Supp. 2015)); and made firearm enhancements
discretionary, rather than mandatory, for such individuals (730 ILCS 5/5-4.5-105(b) (West
Supp. 2015)). In supplemental briefing, Sebastian argues that these amendments should apply
to him retroactively.
¶ 60 In People ex rel. Alvarez v. Howard, 2016 IL 120729, ¶ 28, our supreme court recently
held that the amendment to section 5-130 raising the age of automatic transfer to criminal court
for defendants charged with first degree murder from 15 to 16 years of age applies
retroactively to pending cases. The court explained that Illinois courts apply the two-step
analysis set forth in Landgraf v. USI Film Products, 511 U.S. 244 (1994), first asking “whether
the legislature has clearly indicated the temporal reach of the amended statute” and—only
where it has not—asking “whether the statute would have a retroactive impact.” Howard, 2016
IL 120729, ¶ 19. The court explained further, however, that the general savings clause in
section 4 of the Statute on Statutes (5 ILCS 70/4 (West 2014)) provides a default statement of
temporal reach where one is not otherwise provided. Howard, 2016 IL 120729, ¶ 20.
Substantive changes generally apply prospectively and procedural changes apply retroactively.

- 11 -
 Id. As a result of this savings clause, the court made clear that “an Illinois court will never need
to go beyond step one of the Landgraf test.” Id.
¶ 61 Noting both that nothing in the text of the amendment to section 5-130 itself indicates its
temporal reach and that the effective date of January 1, 2016, was not expressly chosen by the
legislature but applied by default, pursuant to the Effective Date of Laws Act (5 ILCS 75/1(a)
(West 2014)), the Howard court determined that the general savings clause of section 4 of the
Statute on Statutes applied. Howard, 2016 IL 120729, ¶¶ 21-23. As it had earlier held, in
People v. Patterson, 2014 IL 115102, that “ ‘[w]hether a defendant is tried in juvenile or
criminal court is purely a matter of procedure,’ ” the court concluded that the amendment to
section 5-130 should apply retroactively “unless doing so would offend the constitution.”
Howard, 2016 IL 120729, ¶ 28 (quoting Patterson, 2014 IL 115102, ¶ 104). Concluding that
no such constitutional impediment applied, the court held that “the amendment applies to
pending cases.” Id. The Howard court agreed with the State that, under section 4, procedural
amendments will only be applied retroactively “so far as is practicable” but rejected the State’s
contention that the inconvenience of transferring a case that had already been pending in
criminal court for three years to juvenile court precluded retroactive application. Id. ¶ 32. The
court explained that “practicable” is not synonymous with “convenient” but rather with
“feasible.” (Internal quotation marks omitted.) Id.
¶ 62 Although Howard involved a case pending in the circuit court, Sebastian argues the result
should be the same for cases like his, pending on direct appeal. We agree. Only one panel of
this court has concluded otherwise, in a pre-Howard decision that has since been appealed to
the supreme court. See People v. Hunter, 2016 IL App (1st) 141904, ¶ 73, appeal allowed, No.
121306 (Ill. Nov. 23, 2016). We respectfully disagree with the reasoning in Hunter that, even
where the general savings clause in section 4 of the Statute on Statutes provides the missing
statement of intended temporal reach, an amendment may still not be applied retroactively if,
pursuant to the second step of the Landgraf test, it will have a “retroactive impact.” Id. ¶ 72.
Our supreme court subsequently made quite clear in Howard that section 4 obviates the need
for Illinois courts to ever reach the second step of that test. Howard, 2016 IL 120729, ¶ 20. We
agree with our colleagues who concluded, in People v. Scott, 2016 IL App (1st) 141456, ¶ 46,
that the holding in Howard applies to all pending cases. See also People v. Patterson, 2016 IL
App (1st) 101573-B, ¶ 17 (pre-Howard decision reaching same result); People v. Ortiz, 2016
IL App (1st) 133294, ¶ 35 (same).
¶ 63 Because we hold that the amendment to section 5-130 increasing the minimum age for
mandatory transfer of a defendant charged with first degree murder from 15 to 16 applies
retroactively, we vacate Sebastian’s sentence and remand his case to the juvenile court, where
the State may elect to seek a discretionary transfer.
¶ 64 In light of this result, we reach neither Sebastian’s argument that his original sentence was
unconstitutional nor his alternative supplemental argument that he is entitled to a new
sentencing hearing in criminal court pursuant to recent sentencing guidelines for defendants
who were under the age of 18 at the time of their crimes. If, on remand, the juvenile court
exercises its discretion to transfer Sebastian back to criminal court, it will be for the circuit
court to consider the applicability of those statutory amendments in the first instance.

- 12 -
¶ 65 CONCLUSION
¶ 66 For the foregoing reasons, we vacate Sebastian’s sentence, affirm the judgment of the
circuit court in all other respects, and remand this case to the juvenile court.

¶ 67 Affirmed in part; sentence vacated; cause remanded.
