Megan A. Ring, Colorado State Public Defender, Dilyn K. Meyers, Deputy State Public Defender, Denver, Colorado, for Defendant-Appellant ¶1 Defendant, Michael Barnes, appeals his convictions for
aggravated robbery and menacing. He argues, among other things,
that the district court reversibly erred by instructing the jury on the
provocation exception to self-defense. Because we agree, we reverse
the convictions and remand for a new trial on those charges.1
I. Background
¶2 Dominique Thomas owned an old Ford Bronco that was
parked in the parking lot of his apartment complex. The vehicle
was inoperable and had been “out of commission” for two years.
¶3 One evening, Thomas noticed the vehicle’s hood was up, and
there was a second battery connected with wires to the car battery.
There was a screwdriver in the ignition, and it appeared to Thomas
that someone had been trying to steal the vehicle. Thomas duct-
taped the door shut (because it did not lock) and decided to keep
his eye on the vehicle for the rest of the night. A couple hours later,
he saw two people “eyeing” it, but they left when he approached.
¶4 Later that evening, Thomas heard the Bronco running and ran
outside, where he saw Barnes working under the hood and another

trespass. That conviction therefore remains undisturbed.
1 man standing nearby. Thomas went inside, got a rifle, and called
the police, telling them that if they did not arrive in thirty seconds,
he would “shoot these people that’s trying to steal my car.” As
Thomas approached, the other man drove off in a van. Thomas
then told Barnes to get away from the vehicle, but Barnes just
looked at Thomas and went back to working on the vehicle.
¶5 Thomas decided to “knock [Barnes] out with the gun” rather
than shoot him. As he swung the gun at Barnes’s head, Barnes
“sprung into action and put [Thomas] into a chokehold.” During
the ensuing tussle, Thomas took the clip out of his gun and put the
gun down so he could break free. The two men then rolled to the
ground and threw punches at one another before Barnes picked up
the gun and ran to the other side of the sidewalk. According to
Thomas, Barnes pointed the gun at him and “tried to pull the
trigger” before realizing the gun was unloaded. Barnes then fled
with the gun into the apartment complex, where he was arrested.
¶6 Barnes was charged with two counts of aggravated robbery (for
taking the rifle), felony menacing (for threatening Thomas with the
rifle), first degree criminal trespass of a motor vehicle, and a crime
of violence sentence enhancer. At trial, his primary defense to the
2 aggravated robbery and menacing charges was that he took the rifle
from Thomas in self-defense. A jury convicted Barnes as charged.
II. Provocation Instruction
¶7 Barnes argues that the district court erred by instructing the
jury on the provocation exception to self-defense because there was
no evidence that he intentionally goaded Thomas into attacking him
so that he would have a pretext to injure or kill him. We agree.
A. Additional Background
¶8 In Barnes’s post-arrest interview, he told an officer that he was
working under the hood of the Bronco when Thomas “ran up on
[him] and hit [him] in the back of the head with a gun” without
announcing himself or saying anything first. Barnes said he “felt
like [his] life was in danger,” so he grabbed Thomas and threw him
to the ground. During the tussle, Thomas “kept trying to go for the
gun,” and Barnes was trying to keep him away from it.
¶9 Barnes’s theory of defense at trial was that he took the gun
from Thomas in self-defense. The jury was instructed as follows:
It is [Barnes’s] theory of defense that he is not guilty of menacing and aggravated robbery because his actions after he was confronted and physically assaulted by [Thomas] were justified by the affirmative defense of self-
3 defense because he used physical force and took the rifle from [Thomas] to defend himself from what he reasonably believed to be the use of physical force and used a degree of force that was necessary for the purpose of defending himself against [Thomas].
The district court also instructed the jury on self-defense.
¶ 10 The prosecution requested that the court instruct the jury on
the provocation exception to self-defense — namely, that Barnes,
“[w]ith intent to cause bodily injury or death to another person . . .
provoke[d] the use of unlawful physical force by that other person.”
§ 18-1-704(3)(a), C.R.S. 2025. Defense counsel objected, asserting
that there was no evidence that Barnes provoked Thomas’s use of
force through words or physical action toward Thomas.
¶ 11 The district court did not directly address defense counsel’s
objection to the provocation exception, instead focusing its ruling
on its denial of an initial aggressor instruction (which the parties
addressed at the same time). But the court included the
provocation exception in the self-defense jury instruction.
¶ 12 In closing argument, the prosecution told the jury that “this
case is going to come down to whether or not you believe that by
stealing the car, the defendant provoked the victim into acting.”
4 The prosecutor continued: “In order for self-defense to apply, the
defendant cannot provoke the fight . . . by trying to steal that car.”
B. Applicable Law and Standard of Review
¶ 13 When a defendant claims self-defense, one way for the
prosecution to defeat that defense is by proving beyond a
reasonable doubt that the provocation exception applies. People v.
Roberts-Bicking, 2021 COA 12, ¶ 30. But the court may instruct
the jury on the exception only if there is “some evidence” to support
it. Galvan v. People, 2020 CO 82, ¶ 25. Although this threshold is
low, it requires evidence that “would support a reasonable
inference” that the exception applies. Roberts-Bicking, ¶ 31.
¶ 14 Under the provocation exception, a defendant forfeits the right
to self-defense when, “[w]ith intent to cause bodily injury or death
to another person, he provokes the use of unlawful physical force
by that other person.” § 18-1-704(3)(a). The exception has three
elements: “(1) the other person uses unlawful physical force against
[the defendant]; (2) the defendant provoked the use of such physical
force by the other person; and (3) the defendant intended his
provocation to goad the other person into attacking him in order to
provide a pretext to injure or kill that person.” Galvan, ¶ 19.

force by the other person; and (3) the defendant intended his
provocation to goad the other person into attacking him in order to
provide a pretext to injure or kill that person.” Galvan, ¶ 19.
5 ¶ 15 We review de novo whether some evidence exists to support a
provocation instruction, viewing the evidence in the light most
favorable to the giving of the instruction. Roberts-Bicking, ¶ 32.
C. No Evidence to Support Instruction
¶ 16 We agree with Barnes that the record contains no evidence to
support a provocation instruction in this case. Even assuming that
Barnes’s apparent attempt to steal the Bronco could be deemed to
have provoked Thomas to attack him, no evidence supports a
reasonable inference that by attempting to steal the vehicle, Barnes
intended “to goad [Thomas] into attacking him” so that he would
have “a pretext to injure or kill [Thomas].” Galvan, ¶ 19.
¶ 17 Viewing the evidence in the light most favorable to the
prosecution, all Barnes did before Thomas attempted to hit him
with the gun was work on the vehicle and fail to respond when
Thomas told him to get away. The clear implication was that
Barnes was trying to steal the vehicle. There was no suggestion
that his intent was instead to get Thomas to come out of his
apartment and attack him so Barnes could injure Thomas in
response. See id. at ¶ 31 (“[A]bsent evidence of the requisite intent,
the provocation exception cannot defeat the affirmative defense of
6 self-defense.”). There was no indication that Barnes knew Thomas
or had any reason to harm him — much less through such a
convoluted scheme. See People v. Silva, 987 P.2d 909, 913-15
(Colo. App. 1999) (holding that there was no evidence the defendant
intended to provoke a fight to injure the victims where “there was
no meeting or altercation between the two groups” before the fight);
cf. Galvan, ¶ 33 (holding that there was evidence to support a
provocation instruction where the charged assault followed a prior
verbal altercation and unwanted sexual advances); Roberts-Bicking,
¶¶ 9, 40 (holding that there was evidence to support a provocation
instruction where the victim had kicked the defendant out of his
apartment and “previously threatened to physically harm him”).
¶ 18 The People concede there was no evidence of the requisite
intent before Thomas approached Barnes, disclaiming the
prosecution’s argument in the district court that Barnes’s attempt
to steal the car was enough. Now, the People argue that the
provocation occurred when Barnes “looked at” Thomas and then
continued working on the vehicle. They contend that “a reasonable
jury could infer that Barnes’s intent for ignoring [Thomas’s]
command to stop was so that he could commit a surprise attack.”
7 ¶ 19 Not only was this not the theory argued at trial, or the theory
on which the instruction was given, but it is not a reasonable
inference under the facts of this case. First off, for the provocation
exception to apply, Barnes’s intent had to be to get Thomas to
attack him first — not simply to lull him into being vulnerable to a
surprise attack by Barnes. See People v. Rios, 2014 COA 90, ¶ 47.
But more to the point, the People’s theory stretches the “some
evidence” standard too far. The question is not simply whether
Barnes’s conduct may have actually provoked Thomas to attack
him. It is whether Barnes’s purpose in engaging in that conduct —
now characterized as ignoring Thomas’s verbal warning — was to
create a pretext for injuring Thomas. See Galvan, ¶ 19. Given the
lack of any prior interaction between the two, such an inference is
not just “highly improbable”; it makes no sense. Id. at ¶ 24 (citation
omitted); see Castillo v. People, 2018 CO 62, ¶ 64 n.8 (“[I]nferences
may be drawn only from the facts in evidence and [m]ay not be
based on mere speculation or conjecture.” (citation omitted)).
¶ 20 We therefore conclude that the district court erred by
instructing the jury on the provocation exception to self-defense.
8 D. Harmlessness
¶ 21 When the district court erroneously instructs the jury on an
exception to self-defense that lacks evidentiary support, we apply
the nonconstitutional harmless error standard. See Castillo, ¶ 56.
Under this standard, we will reverse “only if the error affects the
substantial rights of the parties,” meaning it “substantially
influenced the verdict or affected the fairness of the trial
proceedings.” Id. at ¶ 57 (citation omitted). An error is not
harmless if there is a “reasonable probability” that it contributed to
the conviction. People v. Schnorenberg, 2025 CO 43, ¶ 52.
¶ 22 We conclude that the provocation instruction was not
harmless for three reasons. First, one problem with an erroneously
given instruction is that “jurors might try to fit facts” into that
instruction. Castillo, ¶ 59. That risk was particularly acute in this
case. Although there was no evidence that Barnes “provoked”
Thomas’s attack within the legal meaning of that term, there was
ample evidence that his apparent attempt to steal the Bronco was
the cause of the attack. There is a reasonable probability that a
jury trying to fit the facts of this case into the instruction could
have found (erroneously) that Barnes lost his right to self-defense
9 merely because he committed a crime that prompted Thomas to
attack him. Cf. People v. Chirico, 2012 COA 16, ¶¶ 14, 18 (holding
that instruction erroneously suggesting the defendant forfeited his
right to self-defense by committing a crime was not harmless).
¶ 23 Second, the prosecutor’s comments in closing argument
played right into that concern. See Castillo, ¶ 60 (noting that errors
in jury instructions can be “exacerbated by the prosecution’s
misleading comments during its closing argument” (citation
omitted)). Not only did the prosecutor “rel[y] heavily” on the
provocation instruction, id. at ¶ 63 — telling the jury the case would
“come down to” provocation — but she urged the jury to apply it in
the problematic, nonlegal sense suggested by the evidence.
¶ 24 Repeatedly, the prosecutor told the jury that Barnes
“provoke[d] the fight . . . by trying to steal the car” — not because
he intended to goad Thomas into attacking him, but because
Thomas had a right to defend his property. In other words, the
prosecutor argued that Barnes could not claim self-defense simply
because he “started” the fight by attempting to steal the vehicle.
Not one mention of Barnes intending to injure Thomas (or that such
intent was required for the jury to find provocation). There is a
10 reasonable probability that a jury faced with the inapplicable
exception and the prosecutor’s incorrect framing of it could have
concluded that Barnes’s act of attempting to steal the car was
provocation — a theory the People rightly abandon on appeal.
¶ 25 Third, there is a reasonable probability that a properly
instructed jury could have found that Barnes acted in self-defense.
See People v. DeGreat, 2018 CO 83, ¶ 27 (noting that acts of
robbery may be justified by self-defense “when the defendant uses
force to disarm an assailant and then flees with the assailant’s
weapon”). It is undisputed that Thomas approached Barnes with a
rifle and swung it at Barnes’s head, while Barnes was unarmed. As
Thomas approached, he told police he was about to shoot the
people trying to steal his car. Moreover, Barnes told police after his
arrest that he “felt like [his] life was in danger” and was just trying
to keep Thomas away from the gun. And although Thomas may
have had the right to use reasonable physical force to prevent the
theft, he had no right to use unreasonable or deadly force. See
§ 18-1-706, C.R.S. 2025. Based on this evidence, a jury could
reasonably have found that Barnes used force to defend himself
from what he reasonably believed to be the use or imminent use of
11 unlawful force by Thomas, and that the degree of force he used was
reasonably necessary for that purpose. See § 18-1-704(1).
¶ 26 The People insist the error was harmless because Barnes’s
theory of self-defense was “overwhelmingly undermined by the
evidence.” In doing so, they show only (perhaps overwhelmingly)
that Barnes was attempting to steal the Bronco. But even if Barnes
was trying to steal the vehicle and knew Thomas was its likely
owner, Barnes would still have been entitled to act in self-defense if
he reasonably believed Thomas’s use of force or imminent use of
force was unreasonable, deadly, or otherwise unlawful. See People
v. Toler, 9 P.3d 341, 352 (Colo. 2000) (“[T]respassers do not forfeit
their rights to self-defense merely by the act of trespassing.”).
¶ 27 We also are unpersuaded that defense counsel cured any
harm by telling the jury that (1) Barnes “was not doing this to
intentionally cause injury or death to [Thomas], and that’s what you
have to find”; and (2) Barnes’s attempt to steal the car was not
provocation. Faced with an instruction that did not otherwise fit
the facts of the case and the prosecutor’s argument that attempting
to steal the car was provocation, defense counsel’s attempt to right
12 the ship does not foreclose a reasonable probability that the jury
understood the exception exactly as the prosecution described it.2
¶ 28 Thus, because there is a reasonable probability that the
erroneously given provocation instruction contributed to Barnes’s
aggravated robbery and menacing convictions, we reverse those
convictions and remand for a new trial on those charges.
III. Other Issues
¶ 29 Barnes raises several other challenges to the jury instructions,
but he asserts that we need not reach those issues if we reverse his
convictions based on the provocation instruction. We agree.
¶ 30 The parties dispute whether Barnes’s other instructional
challenges are preserved. And although we tend to agree with
Barnes that they were, we agree with the People that they were not
articulated or developed in the district court in precisely the same
manner or to the same degree as they are on appeal. On remand,
2 The People also argue that the error was harmless because the
jurors did not “grapple with” the provocation instruction like the jury did in Castillo v. People, 2018 CO 62, ¶ 65. But while a juror question about the exception might indicate the jury was “closely considering” the exception, id., the converse is not necessarily true. The jury might not have asked a question because it believed it understood the instruction, in the sense argued by the prosecutor.
13 the parties and the district court will have an opportunity to better
develop the record on these issues in light of this opinion. We thus
cannot say the issues are likely to “arise in precisely the same
posture” at a new trial. People v. Gulyas, 2022 COA 34, ¶ 29.3
¶ 31 As for Barnes’s argument that his two aggravated robberies
should merge, which the People concede, that issue could arise
again only if Barnes is convicted of both counts after retrial and the
district court does not merge them, despite the People’s concession.
IV. Disposition
¶ 32 Barnes’s aggravated robbery and menacing convictions are
reversed, and the case is remanded for a new trial.
JUDGE WELLING and JUDGE LUM concur.
3 Because we are reversing Barnes’s convictions based on the
provocation instruction, we need not address his cumulative error argument either. See Howard-Walker v. People, 2019 CO 69, ¶ 25 (explaining that cumulative error may require reversal when no single error prejudices the defendant’s substantial rights, but the combination of multiple errors does).
