*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art. VI, § 5(3), and § 24-51-1105, C.R.S. 2025. ¶1 Defendant, Michael Lyne Green, appeals the judgment of
conviction entered on jury verdicts finding him guilty of
misdemeanor possession of a controlled substance and felony
aggravated motor vehicle theft.
¶2 We reject the only argument implicating the drug possession
conviction and therefore affirm that conviction. But we agree that
the trial court erred by admitting extensive CRE 404(b) evidence at
Green’s trial without conducting the proper analysis, so we reverse
the motor vehicle theft conviction and remand for a new trial.
I. Background
¶3 Green and two other men were in a Kohl’s store when Lyndia
High, the store’s loss prevention supervisor, observed them on the
store’s surveillance system engaging in behaviors that she thought
were consistent with shoplifting. She called the police.
¶4 Before the police arrived, High rewound the surveillance video
to track the group’s path from a car in the parking lot to the store
entrance. Using the camera’s zoom feature, she saw a man in a
blue sweatshirt exit the driver’s side of the car and two other men,
one in a white sweatshirt and one in a black jacket, get out of the
car from the passenger side. Following her review of the
1 surveillance footage, High gave the police dispatcher a physical
description of the men and told the dispatcher that they had arrived
in a silver sedan parked in the store’s lot.
¶5 When the police arrived, they located the silver Kia sedan and
ran the car’s Florida license plate number. The search revealed no
vehicle information associated with that license plate number, so
officers ran the vehicle identification number (VIN) and discovered
that the Kia was registered in Tennessee and had been reported
stolen in Arvada. Based on this information, the officers blocked
the Kia with their patrol cars, and one officer searched the car.
¶6 The Kia’s ignition was damaged. The officer saw a flathead
screwdriver in the center console. He also found a key in the
console, but the key did not start the Kia. The officer deduced that
the driver of the Kia had used the flathead screwdriver to start the
car. The officer removed the Florida license plate and discovered
the Tennessee license plate matching the Kia’s VIN underneath.
2 ¶7 While that officer searched the car, other officers entered
Kohl’s to contact the suspected shoplifters whom High had
connected to the stolen Kia.1
¶8 The man in the blue sweatshirt was identified as Green.
Officers searched Green and found a Dodge car key, two glass
pipes, and a small white rock, later identified as cocaine, in his
pockets. They also reviewed the security footage High had used to
connect the three men to the Kia. Green was arrested and charged
with aggravated motor vehicle theft and unlawful possession of a
controlled substance.
¶9 On the first day of trial, defense counsel moved to exclude any
evidence that police had been called to Kohl’s to investigate
suspected shoplifting. Defense counsel contended that the evidence
was extrinsic to the charged offenses, constituted impermissible
character evidence under CRE 404(b), lacked probative value, and
was unduly prejudicial under CRE 403. The prosecutor argued
that the evidence of the suspected shoplifting was “important and
1 While police were checking the license plate information on the
Kia, one of the three men High had identified as a suspected shoplifter left Kohl’s and fled on foot. Police searched the area but were unable to locate or identify him.
3 relevant . . . to give the jury complete context of the facts in this
case” and to explain why police had responded to Kohl’s. The trial
court denied defense counsel’s motion without explanation.
¶ 10 The prosecutor began her opening statement by explaining
that High had suspected Green and the other men of shoplifting.
High testified about the suspected shoplifting, as did three police
officers. The suspected shoplifting conduct was also depicted in
several video and photo exhibits. One exhibit, narrated by High
during her testimony, was a five-minute video of the inside of Kohl’s
that showed the three men walking into the store and then
engaging in suspected shoplifting.
¶ 11 The prosecution presented its evidence in one day. At the
conclusion of the trial, the jury returned guilty verdicts on both
charges. The jury also determined, based on the value of the Kia,
that the aggravated motor vehicle theft was a class 5 felony. The
trial court subsequently found that Green had two prior motor
vehicle theft convictions that were separately brought and tried,
which elevated the aggravated motor vehicle theft conviction to a
class 3 felony. The trial court sentenced Green to six years in
prison.
4 II. Analysis
¶ 12 We begin with Green’s challenge to the 2022 model criminal
jury instruction on reasonable doubt, the only issue on appeal that
applies to the drug possession conviction as well as the motor
vehicle theft conviction.2 Because we reject that challenge, we
affirm the drug possession conviction. From there, we turn to
Green’s claim concerning the admission of CRE 404(b) evidence.
Because we agree that the court erred in admitting the evidence
without conducting the proper analysis or giving a limiting
instruction, we reverse the motor vehicle theft conviction and
remand for a new trial. Last, we address the one issue likely to
arise on remand.
A. Jury Instruction on Reasonable Doubt
¶ 13 Before 2022, the Colorado model criminal jury instructions
defined reasonable doubt as follows:
2 Aside from a brief reference in the background section of the forty-
five-page opening brief, Green never mentions the drug possession conviction, nor does he present any argument concerning that conviction. To the extent he intended his other arguments to apply to the drug conviction, he does not explain the connection. Accordingly, the arguments are too undeveloped to permit review. See People v. Stone, 2021 COA 104, ¶ 52 (explaining that the appellate court will not address undeveloped arguments).
5 Reasonable doubt means a doubt based upon reason and common sense which arises from a fair and rational consideration of all of the evidence, or the lack of evidence, in the case. It is a doubt which is not a vague, speculative or imaginary doubt, but such a doubt as would cause reasonable people to hesitate to act in matters of importance to themselves.
COLJI-Crim. E:03 (2021).
¶ 14 In 2022, the model instruction was substantially revised:
Every person charged with a crime is presumed innocent. This presumption of innocence remains with the defendant throughout the trial and should be given effect by you unless, after considering all the evidence, you are convinced that the defendant is guilty beyond a reasonable doubt.
The burden of proof in this case is upon the prosecution. The prosecution must prove to the satisfaction of the jury beyond a reasonable doubt the existence of each and every element necessary to constitute the crime charged. This burden requires more than proof that something is highly probable, but it does not require proof with absolute certainty.
Proof beyond a reasonable doubt is proof that leaves you firmly convinced of the defendant’s guilt. If you are firmly convinced of the defendant’s guilt, then the prosecution has proven the crime charged beyond a reasonable doubt. But if you think there is a real possibility that the defendant is not guilty,
6 then the prosecution has failed to prove the crime charged beyond a reasonable doubt.
After considering all the evidence, if you decide the prosecution has proven each of the elements of a crime charged beyond a reasonable doubt, you should find the defendant guilty of that crime.
After considering all the evidence, if you decide the prosecution has failed to prove any one or more of the elements of a crime charged beyond a reasonable doubt, you should find the defendant not guilty of that crime.
COLJI-Crim. E:03 (2022).
¶ 15 Over Green’s objection, the court instructed the jury on
reasonable doubt using the 2022 version of the model instruction
rather than the prior version.
¶ 16 Green contends that the 2022 instruction impermissibly
lowered the prosecution’s burden of proof, undercut the
presumption of innocence, and shifted the burden of proof to him.
We disagree.
1. Legal Principles and Standard of Review
¶ 17 The trial court must properly instruct the jury on the
reasonable doubt standard. Tibbels v. People, 2022 CO 1, ¶ 25.
Whether the court’s instruction lowered the prosecution’s burden of
proof is a question of law that we review de novo. Id. at ¶ 22. “An
7 instruction that lowers the prosecution’s burden of proof below
reasonable doubt constitutes structural error and requires
automatic reversal.” Johnson v. People, 2019 CO 17, ¶ 8.
2. Application
¶ 18 While Green’s appeal was pending, three divisions of this court
considered similar challenges to the 2022 model reasonable doubt
instruction. See People v. Melara, 2025 COA 48, ¶¶ 22-23; People v.
Schlehuber, 2025 COA 50, ¶¶ 16-17; People v. Berumen, 2025 COA
93, ¶ 14. In all three cases, the majority opinions concluded that
the 2022 instruction did not lower the prosecution’s burden of proof
below the reasonable doubt standard. Melara, ¶ 24; Schlehuber,
¶ 20; Berumen, ¶ 21. We agree with those majority opinions and
adopt their reasoning to resolve Green’s arguments.
¶ 19 First, the 2022 model instruction’s omission of the specific
language directing the jury that it may consider “the lack of
evidence” does not lower the prosecution’s burden of proof because
the instruction as a whole informs the jury that “if the prosecution
fails to present sufficient evidence of guilt, it will not have met its
burden.” Schlehuber, ¶ 22; see also Melara, ¶ 24; Berumen, ¶ 33.
8 ¶ 20 Next, though the “hesitate to act” phrase was previously
approved by Colorado courts, Green does not explain why the
deletion of that phrase lowers the prosecution’s burden of proof.
Moreover, we reject Green’s contention that “the jury was left
without anything tangible to understand the concept of ‘reasonable
doubt’” by the omission of this phrase, as the instruction as a whole
renders the concept sufficiently concrete. We agree with the
Schlehuber division that omission of the phrase clarifies the
reasonable doubt standard by discouraging courts from using
analogies to explain it. See Schlehuber, ¶ 27.
¶ 21 Finally, defining proof beyond a reasonable doubt as proof that
leaves jurors “firmly convinced” of the defendant’s guilt and
reasonable doubt as “a real possibility that the defendant is not
guilty” does not lower the prosecution’s burden of proof. COLJI-
Crim. E:03 (2022). “The phrase ‘firmly convinced’ correctly
connotes a standard of ‘near certitude,’” Schlehuber, ¶ 31 (quoting
Jackson v. Virginia, 443 U.S. 307, 315 (1979)), while the phrase
“real possibility” correctly requires the prosecution to dispel any
legitimate possibility the defendant is not guilty, “not just a serious
or substantial one,” id. at ¶ 32. And like the Berumen majority, we
9 disagree that the use of the phrase “real possibility” “warrants
reversal because courts in other jurisdictions have criticized or
rejected similar language.” Berumen, ¶ 23.
¶ 22 We acknowledge that Judge Berger’s partial dissent in
Berumen raises legitimate concerns about the use of the “real
possibility” language but, ultimately, we agree with the Berumen
majority that the use of that phrase, when considered in context
and as a part of the instructions as a whole, does not shift the
prosecution’s burden. Id. at ¶¶ 26-30; see id. at ¶¶ 60-79 (Berger,
J., concurring in part and dissenting in part). And we echo Judge
Berger’s observation that, should they share his concerns about the
revised model instruction, trial courts retain discretion to use the
well-tested 2021 model instruction while the revised model
instruction is under review by our supreme court.3 Id. at ¶ 78 &
n.5 (Berger, J., concurring in part and dissenting in part).
3 The Colorado Supreme Court has granted certiorari in Teran-
Sanchez v. People, (Colo. No. 25SC148, Sep. 2, 2025) (unpublished order), to address whether the definition of reasonable doubt in the revised model instruction violates a defendant’s rights to due process and a fair trial.
10 ¶ 23 Considering the reasonable doubt instruction as a whole, we
perceive no cumulative error because there is not a reasonable
likelihood that the instruction would “allow a conviction based on a
standard lower than beyond a reasonable doubt.” Schlehuber, ¶ 35
(quoting Tibbels, ¶ 36).
¶ 24 Accordingly, we discern no error in the court’s decision to give
the 2022 model instruction. Because Green’s challenge to the 2022
model instruction is the only claim of error related to his
misdemeanor drug conviction, and the trial court did not err by
giving that instruction to the jury, we affirm the misdemeanor
conviction.
B. Admission of Suspected Shoplifting Evidence
¶ 25 Green contends that the trial court erred by admitting
evidence of the suspected shoplifting without conducting the
required CRE 404(b) analysis or issuing a limiting instruction. We
agree.
¶ 26 Admission of uncharged misconduct evidence — often referred
to as “other acts evidence” — is restricted under the rules of
evidence because of its potential to unfairly prejudice a defendant.
11 Perez v. People, 2015 CO 45, ¶ 24. CRE 404(b)(1) prohibits the
admission of such evidence if offered to prove a person’s character
and to show that the person acted in conformity with a character
trait on a particular occasion — often described as “a propensity to
commit the charged offense.” Rojas v. People, 2022 CO 8, ¶ 52.
¶ 27 Nonetheless, under the now-defunct res gestae doctrine,
courts would frequently admit evidence of the defendant’s prior
misconduct related to the charge on trial to “provide the fact-finder
with a full and complete understanding of the events surrounding
the crime and the context in which the charged crime occurred.”
People v. Skufca, 176 P.3d 83, 86 (Colo. 2008) (citation omitted),
abrogated in part by, Rojas, ¶ 33. But because res gestae became a
convenient way to “‘short-circuit[] the evaluation called for in Rule
404(b)’ analysis,” Rojas, ¶ 37 (citation omitted), permitting the
introduction of otherwise inadmissible character evidence, the
supreme court abolished the res gestae doctrine and adopted a new
framework for determining when CRE 404(b) governs the admission
of other acts evidence, id. at ¶¶ 3-4, 41, 43.
¶ 28 To determine whether CRE 404(b) is triggered, a court must
first assess if the evidence is intrinsic or extrinsic to the charged
12 offense. Id. at ¶ 52. “Intrinsic acts are those (1) that directly prove
the charged offense or (2) that occurred contemporaneously with
the charged offense and facilitated the commission of it.” Id.
“Evidence of acts that are intrinsic to the charged offense are
exempt from Rule 404(b) because they are not ‘other’ crimes,
wrongs, or acts.” Id.
¶ 29 If the evidence is not intrinsic, then it is extrinsic. Id. at ¶ 44.
And if the extrinsic evidence suggests bad character, it is
admissible only if it satisfies the test articulated in People v. Spoto,
795 P.2d 1314, 1318 (Colo. 1990). Rojas, ¶ 52. Under this test, a
trial court must find that the evidence (1) “relates to a material
fact”; (2) is “logically relevant”; (3) has such relevance “independent
of the intermediate inference, prohibited by CRE 404(b), that the
defendant has a bad character” and acted in conformity therewith;
and (4) satisfies CRE 403 by having probative value that is not
“substantially outweighed by the danger of unfair prejudice.” Spoto,
795 P.2d at 1318. If a trial court determines that the evidence is
admissible under CRE 404(b), “the court must also, upon request,
contemporaneously instruct the jurors of the limited purpose for
which the evidence may be considered.” Rojas, ¶ 27.
13 ¶ 30 Trial courts have substantial discretion in deciding whether to
admit other acts evidence. Perez, ¶ 22. We review the trial court’s
ruling for an abuse of discretion, and we will not disturb the
decision unless it was manifestly arbitrary, unreasonable, or unfair.
Id. Because Green preserved his claim, if we conclude that the
court abused its discretion, we must reverse his conviction unless
the error was harmless, meaning “there is no reasonable
probability, or possibility, that it contributed to the defendant’s
conviction.” People v. Roman, 2017 CO 70, ¶ 13 (footnote omitted)
(citing Crider v. People, 186 P.3d 39, 42-43 (Colo. 2008)).
¶ 31 Green argues that the evidence that he was suspected of
shoplifting was extrinsic to the charged crimes, and therefore, the
trial court erred by admitting the evidence without conducting a
Spoto analysis or issuing a limiting instruction. The People contend
that the evidence was either intrinsic and admissible under CRE
401 and 403, or it was extrinsic but nonetheless admissible under
Spoto, and, regardless, any error in admitting the evidence was
harmless. We agree with Green.
14 ¶ 32 At trial, the prosecutor argued that because the shoplifting
evidence “provide[d] complete context” for the jury, CRE 404(b) did
not apply. To the extent the court adopted that position, it erred.
See Rojas, ¶ 38 (“The ‘completing the story’ rationale to admit other-
acts evidence ‘create[s] the greatest risk of subverting the
limitations that ought to apply whenever the jury is informed of a
person’s uncharged wrongdoing.’” (quoting David P. Leonard, New
Wigmore on Evidence: Evidence of Other Misconduct § 5.3.2 (2d ed.
Supp. 2020))). However, because the trial court denied Green’s
motion without explanation, we do not know the basis of its
decision. In other words, it might have concluded that, for some
other reason, the evidence was not subject to CRE 404(b).
Therefore, we turn to that issue.
¶ 33 As required by Rojas, we first consider whether the evidence of
suspected shoplifting is intrinsic or extrinsic to the charged offense
of aggravated motor vehicle theft. Id. at ¶ 52.
¶ 34 The People argue that the evidence is intrinsic to the charged
offense, on the theory that Green’s “intent to shoplift at Kohl’s
facilitated [aggravated motor vehicle theft] because shoplifting
15 motivated him to get in the car and drive it to Kohl’s.” We reject
that argument.
¶ 35 To “facilitate” means to “make the commission of (a crime)
easier.” Black’s Law Dictionary 732 (12th ed. 2024). Green’s
suspected shoplifting did not make the alleged theft of the Kia
easier. Indeed, the suspected shoplifting occurred after the alleged
theft of the Kia was completed, which also demonstrates the two
acts were not contemporaneous. Perhaps, under different
circumstances, the inverse argument could be made — that the
alleged theft of the Kia facilitated the shoplifting. But under these
circumstances, the suspected shoplifting could not have facilitated
the earlier theft of a car.
¶ 36 We therefore conclude that the shoplifting evidence was
extrinsic to the charged offense. And because the shoplifting
evidence suggested Green had bad character and a propensity to
steal (i.e., to commit the charged crime of aggravated motor vehicle
theft), CRE 404(b) governed the admission of the evidence.
¶ 37 The trial court, however, did not conduct the required Spoto
analysis before admitting the suspected shoplifting evidence. The
16 failure to conduct the analysis amounts to an abuse of discretion.
Rojas, ¶ 54.
¶ 38 The People invite us to perform the required Spoto analysis for
the first time on appeal, but we decline that invitation. For one
thing, that is not the approach the supreme court took in Rojas.
See id. at ¶¶ 54-55 (proceeding directly to a harmlessness analysis
after concluding that the trial court abused its discretion by failing
to conduct a Spoto analysis). But more importantly, the sheer
volume and disparateness of the admitted CRE 404(b) evidence
complicates the endeavor. It is possible that some evidence of
Green’s suspected shoplifting activity is admissible for a non-
propensity purpose, but the trial court must sift through the
proffered evidence and weigh its probative value against the
prejudicial effect, particularly in the aggregate. And if such
evidence is admitted, it must be admitted with the “accompanying
procedural safeguards” required by CRE 404(b). Id. at ¶ 54.
¶ 39 What we can say with no trouble is that the court’s error in
admitting all of the shoplifting evidence was not harmless. The
issue at trial was whether Green had stolen the Kia. His defense
was identity — he claimed that he was not the driver and had not
17 knowingly obtained or exercised control over the car. See § 18-4-
409(2), C.R.S. 2022.
¶ 40 Notwithstanding the elements of the charged offense and
Green’s defense, the court admitted extensive evidence that Green
was potentially stealing from a store on the night he was arrested
for stealing a car. Of the seven witnesses who testified, four
mentioned the suspected shoplifting conduct. The prosecution’s
first witness narrated a five-minute video that showed nothing more
than Green and two others engaging in conduct consistent with
shoplifting. Three police officers mentioned that they were
dispatched to the store based on a report that three men were
“going to conduct a run-out” from the store. All of this evidence
was presented during what was effectively a one-day trial. Cf.
Howard-Walker v. People, 2019 CO 69, ¶ 40 (where “entire trial
itself lasted less than nine hours (excluding voir dire and jury
deliberations),” the impact of the errors was “compound[ed]”).
¶ 41 And even if, as we have noted, some of this evidence might
have been admissible under CRE 404(b), “the absence of a limiting
instruction permitted the jury to misuse the evidence.” Rojas, ¶ 56.
The People contend that a limiting instruction was unnecessary
18 because Green failed to request one. But in this case, the court
apparently agreed with the prosecution that CRE 404(b) did not
apply and admitted the evidence without conducting the proper
analysis. Under the circumstances, Green did not have a basis to
request a CRE 404(b) limiting instruction. See Rojas, ¶ 27
(explaining that if a court finds evidence admissible under CRE
404(b), then it must consider any request for a limiting instruction).
¶ 42 We likewise disagree with the People’s position that any error
was harmless given the overwhelming evidence of guilt. The
evidence the People rely on is evidence that the Kia was stolen —
the license plate and VIN search revealed that the Kia was reported
stolen, the ignition was “punched,” a flathead screwdriver
(apparently used to start the car) was located in the center console,
the key in the center console did not start the car, and the Florida
license plate displayed on the Kia was covering the registered
Tennessee plate. But the fact that the Kia was stolen was not
seriously in dispute. And none of that evidence connects the stolen
Kia to Green.
¶ 43 The only evidence connecting Green to the Kia was the Kohl’s
surveillance footage, taken together with High’s and the testifying
19 officers’ interpretation of that footage. By their accounts, the
footage was grainy, taken from a distance, included rows of cars
surrounding the Kia, and featured a tree obstructing the view of the
Kia’s windshield, blocking the view of anything or anyone inside the
car. Indeed, Green’s theory of defense focused on the inadequacies
of the video evidence, including that the footage did not show the
Kia arriving to the parking lot and that the footage was nearly
indecipherable because of poor picture quality.
¶ 44 True, High and the officers testified that, using a special
feature only available in the loss prevention office, they viewed a
magnified version of the footage that showed Green emerge from the
driver’s side of the Kia. The jury could have credited those
witnesses’ out-of-court perceptions. But if it did not, then it had to
rely on the less sophisticated, lower-quality version of the footage
admitted at trial, and the jury might not have found that version
particularly elucidating. Given those options available to the jury
and the absence of any other evidence connecting Green to the Kia,
we cannot say that the evidence that Green stole the car was
overwhelming.
20 ¶ 45 Rather, we think there is a reasonable possibility that
admitting the extensive shoplifting evidence, “without any [CRE]
404(b) safeguards, affected the fairness of the trial by allowing the
jury to convict [Green] based on implied propensity” — he is a thief
who steals from stores; therefore, he likely stole the car. Id. at ¶ 56;
see Roman, ¶ 13. In other words, we conclude that the erroneously
admitted evidence might well have “tipped the scales” in favor of the
prosecution. Yusem v. People, 210 P.3d 458, 470 (Colo. 2009); see
also People v. Jefferson, 2014 COA 77M, ¶¶ 27-30 (trial court’s
evidentiary error was not harmless where alleged victim’s credibility
was main issue at trial, evidence of guilt was not overwhelming, and
prosecution emphasized the evidence during trial), aff’d, 2017 CO
35. Accordingly, we conclude that the trial court’s error was not
harmless.
21 C. “Punched” Ignition Testimony
¶ 46 Because the issue is likely to arise on remand,4 we briefly
address Green’s contention that an officer’s testimony about
“punched” ignitions amounted to improper expert testimony.
¶ 47 “Under CRE 701, lay witness opinion testimony must be
(1) rationally based on the witness’ perception; (2) ‘helpful to a clear
understanding of the witness’ testimony or the determination of a
fact in issue’; and (3) ‘not based on scientific, technical, or other
specialized knowledge within the scope of [CRE] 702.’” People v.
Williams, 2025 COA 26, ¶ 30 (quoting CRE 701). Whether an
opinion is lay testimony under CRE 701 or expert testimony under
CRE 702 depends on the basis for the opinion. Venalonzo v. People,
2017 CO 9, ¶ 23.
4 We do not address Green’s remaining claims, as they are unlikely
to arise on remand in the same posture. For example, the Supreme Court’s intervening decision in Erlinger v. United States, 602 U.S. 821, 835 (2024), resolves Green’s challenge to the enhancement of his conviction from a class 5 felony to a class 3 felony. It is now clear that the jury must determine on remand whether Green’s prior convictions were “separately brought and tried.” § 18-4- 409(3)(b), C.R.S. 2022; see also People v. Gregg, 2025 CO 57, ¶ 24 (“[T]he question of separate and distinct criminal episodes demands a jury finding . . . .”).
22 ¶ 48 “Police officers’ testimony may sometimes walk a fine line
between lay and expert testimony.” Williams, ¶ 31 (citing People v.
Stewart, 55 P.3d 107, 123 (Colo. 2002)). “[I]f an ordinary person
could form the officer’s opinion using ‘a process of reasoning
familiar in everyday life, it is admissible as lay opinion evidence.’”
Id. (quoting People in Interest of D.I., 2015 COA 136, ¶ 29). “If, on
the other hand, the [officer] provides testimony that could not be
offered without specialized experiences, knowledge, or training, then
the [officer] is offering expert testimony.” Venalonzo, ¶ 16.
¶ 49 Green argues that the officer gave expert testimony about
punched ignitions in the guise of lay testimony. Some of the
officer’s testimony — including his observations about the ignition
appearing damaged and the presence of the screwdriver in the Kia
— was proper because it was based on his “perceptions and
experiences.” People v. Rincon, 140 P.3d 976, 982 (Colo. App. 2005)
(citation omitted). However, we caution that, on remand, the trial
court must carefully assess the basis of the officer’s opinion that
the Kia’s ignition was “punched” and that the screwdriver was used
to operate the Kia before admitting such testimony as lay testimony.
See Stewart, 55 P.3d at 124 (police officer with specialized training
23 may testify as a lay witness to observations and investigation at the
crime scene but may not testify about deductions regarding a car’s
speed, direction, and trajectory without being qualified as an expert
witness).
¶ 50 At trial, the officer testified that his knowledge of punched
ignitions and his ability to identify a punched ignition were gained
through his training and experience as a police officer, which is a
“hallmark” of expert testimony. People v. Ramos, 2012 COA 191,
¶ 18, aff’d, 2017 CO 6; see People v. Dominguez, 2019 COA 78, ¶ 42
(where officer’s opinion was expressly based on his training and
experience, it constituted an expert opinion). And we note that the
owner of the car was unfamiliar with the term “punched ignition.”
¶ 51 Therefore, if the issue arises on remand, the trial court should
parse the officer’s opinions to ensure that his testimony does not
cross the line into expert territory.
III. Disposition
¶ 52 The judgment of conviction for unlawful possession of a
controlled substance is affirmed. The judgment of conviction for
aggravated motor vehicle theft is reversed, and the case is
remanded for a new trial on that charge.
24 JUDGE SCHOCK concurs.
JUDGE TAUBMAN concurs in part and dissents in part.
25 JUDGE TAUBMAN, concurring in part and dissenting in part.
¶ 53 I agree with the majority’s reversal of the aggravated motor
vehicle theft conviction of defendant, Michael Lyne Green. However,
I dissent in part because I would reverse his drug possession
conviction and remand that charge for a new trial using a different
reasonable doubt instruction.
¶ 54 As the majority notes, the validity of the supreme court’s 2022
model criminal jury instruction on reasonable doubt has been
challenged in several cases, including one in which the supreme
court has granted certiorari. See supra ¶¶ 18, 22 n.3 (citing Teran-
Sanchez v. People, (Colo. No. 258SC148, Sep. 2, 2025) (unpublished
order)).
¶ 55 I write separately because I agree with Judge Berger’s
persuasive dissent in People v. Berumen, 2025 COA 93, ¶¶ 60-79,
___ P.3d ___ , ___ (Berger, J., concurring in part and dissenting in
part), that the third paragraph of the 2022 model jury instruction
on reasonable doubt impermissibly lowers the prosecution’s burden
of proof. That paragraph, in pertinent part, states, “[I]f you think
there is a real possibility that the defendant is not guilty, then the
26 prosecution has failed to prove the crime charged beyond a
reasonable doubt.” COLJI-Crim. E:03 (2022).
¶ 56 While the majority correctly notes that Judge Berger’s partial
dissent raises legitimate concerns and emphasizes that trial judges
are not required to use the 2022 model instruction, the trial court
did so here over Green’s objection. See supra ¶¶ 15, 22. Thus, the
possibility that a trial court may not use the 2022 model instruction
does not resolve the issue of its actual use here.
¶ 57 I agree with the majority’s rejection of Green’s other challenges
to the 2022 model instruction, but I believe that the use of the “real
possibility” language in that instruction is problematic. Instead of
providing clarity to jurors regarding the meaning of “reasonable
doubt,” this language creates ambiguity. That ambiguity is clearly
illustrated in this case by the prosecutor’s closing argument
explaining at length the meaning of “real possibility” without
emphasizing the prosecution’s burden of proof to establish guilt
beyond a reasonable doubt.
¶ 58 I believe that the 2022 model instruction was motivated by the
supreme court’s rejection of a hypothetical used by a trial judge in
Tibbels v. People, 2022 CO 1, ¶¶ 49-53, 501 P.3d 792, 801-02, to
27 explain the “hesitate to act” language in the previous model
instruction. Nevertheless, removal of the “real possibility” language
from the 2022 model jury instruction would simplify and clarify for
jurors the meaning of “proof beyond a reasonable doubt.”
¶ 59 Accordingly, I concur in part and dissent in part and urge the
supreme court to delete the “real possibility” language from the
2022 model instruction.
