*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, Davoisier Tryels, appeals his convictions for first
degree assault causing serious bodily injury, first degree trespass,
third degree assault, child abuse, and first degree burglary as a
crime of violence. He argues that (1) the prosecution presented
insufficient evidence to prove that the victim suffered serious bodily
injury; (2) the district court erred by excluding a defense witness;
and (3) the trespass and burglary convictions must merge. We
agree with the last contention, reverse that portion of the judgment,
and remand to the district court to merge the trespass and burglary
convictions and amend the mittimus accordingly. We otherwise
affirm the judgment.
I. Background
¶2 One summer evening, the victim — Tryels’ former romantic
partner and the mother of his child — was at her apartment with
her sister, their grandmother, and three children. The victim’s
sister heard someone banging on the door. When she opened the
door, Tryels and an unknown woman “busted” into the apartment.
¶3 Upon entering the apartment, the woman punched the victim’s
sister in the face while Tryels headed straight toward the victim’s
bedroom. Tryels forced his way into the bedroom, knocked the
1 victim backward into a dresser, and began strangling her with both
hands for about forty-five seconds. After the victim fell to the
ground, Tryels punched her in the face and began strangling her
again. During the second strangling, the victim felt like she was
going to have a seizure and “blacked out.”
¶4 As Tryels was strangling the victim, the victim’s sister saw
their grandmother trying to pull Tryels off the victim. The victim’s
sister then went to a neighbor’s home and called 911.
¶5 The next thing the victim remembered was waking up in the
hospital.
¶6 The prosecution charged Tryels with violation of a protection
order, first degree assault, first degree trespass, third degree
assault, child abuse, first degree burglary as a crime of violence,
criminal mischief, and telephone obstruction.1
¶7 After a four-day trial, the jury acquitted Tryels of criminal
mischief and telephone obstruction but convicted him of the
remaining charges.
1 The prosecution bifurcated the violation of a protection order
count and later dismissed it.
2 ¶8 The district court sentenced Tryels to a controlling sentence of
fifteen years in prison.
II. Sufficiency of the Evidence
¶9 Tryels contends that the prosecution failed to present
sufficient evidence to establish serious bodily injury, which is an
element of first degree assault and a sentence enhancer for first
degree burglary. We disagree.
¶ 10 “[W]e review the record de novo to determine whether the
evidence before the jury was sufficient both in quantity and quality
to sustain the defendant’s conviction.” Johnson v. People, 2023 CO
7, ¶ 13 (citation omitted). To do that, we consider whether the
evidence, viewed as a whole and in the light most favorable to the
prosecution, is “substantial and sufficient to support a conclusion
by a reasonable mind” that the defendant is guilty of the charges
beyond a reasonable doubt. Id. (citation omitted).
¶ 11 As relevant here, a person commits assault in the first degree
by strangulation if, “[w]ith the intent to cause serious bodily injury,
he . . . applies sufficient pressure to impede or restrict the
breathing or circulation of the blood of another person by applying
such pressure to the neck . . . of the other person and thereby
3 causes serious bodily injury.” § 18-3-202(1)(g), C.R.S. 2025. And
with respect to first degree burglary, a person is subject to crime of
violence sentencing if he causes serious bodily injury to any person
except another participant during the commission of the crime or in
the immediate flight therefrom. See § 18-1.3-406(2)(a)(I)(B),
(2)(a)(II)(H), C.R.S. 2025.
¶ 12 Serious bodily injury means, as pertinent here, “bodily injury
that, either at the time of the actual injury or at a later time,
involves . . . a substantial risk of protracted loss or impairment of
the function of any part or organ of the body.” § 18-1-901(3)(p),
C.R.S. 2025.
¶ 13 At trial, the victim testified that Tryels put both of his hands
on her neck twice and confirmed that she lost consciousness during
the second incident. She said she remembered feeling like she was
going to have a seizure, “blacked out,” and woke up in a hospital.
¶ 14 The jury also heard from a forensic nurse examiner (FNE) who
conducted a physical exam and strangulation assessment when the
victim was in the hospital. The FNE documented signs of
strangulation, including petechiae inside the victim’s cheek and
bruising around her neck. And she documented the victim’s
4 reported symptoms, including loss of consciousness during the
strangulation and post-strangulation neck pain, neck swelling,
headache, numbness, weakness, and memory loss.
¶ 15 The FNE also explained to the jury that when blood doesn’t get
to the brain — known as an anoxic event — the result is permanent
brain cell death. And she testified that if someone loses
consciousness, “they had an anoxic event.” Based on the victim’s
description of events and reported loss of consciousness, the FNE
opined that the victim had suffered a serious bodily injury,
specifically, “an anoxic” injury that resulted in “substantial risk of
protracted loss or impairment of an organ, which was the brain.”
¶ 16 An emergency room doctor testified that although he did not
examine the victim, he reviewed her CT scan, which showed “no
immediate risk of death.”2 Based on the negative CT scan, the
doctor found no serious bodily injury. But he confirmed that a CT
scan doesn’t show all injuries. And while he did not opine on
2 The doctor testified that a CT scan, or a CAT scan, is “a machine
that you go into. There’s a computer that sends radiation into [your] body.” Then “[c]ertain tissues reflect this radiation,” which “comes back to the machine so it can generate pictures on a computer screen.”

that “at some point if you cut off oxygen to somebody’s brain, brain
cells will die.” And once those brain cells die, they are “gone

degree burglary. We disagree.
¶ 10 “[W]e review the record de novo to determine whether the

with respect to first degree burglary, a person is subject to crime of

except another participant during the commission of the crime or in
the immediate flight therefrom. See § 18-1.3-406(2)(a)(I)(B),
(2)(a)(II)(H), C.R.S. 2025.
¶ 12 Serious bodily injury means, as pertinent here, “bodily injury
that, either at the time of the actual injury or at a later time,
involves . . . a substantial risk of protracted loss or impairment of
the function of any part or organ of the body.” § 18-1-901(3)(p),
C.R.S. 2025.
¶ 13 At trial, the victim testified that Tryels put both of his hands
on her neck twice and confirmed that she lost consciousness during
the second incident. She said she remembered feeling like she was
going to have a seizure, “blacked out,” and woke up in a hospital.

brain cell death. And she testified that if someone loses

specifically, “an anoxic” injury that resulted in “substantial risk of

5 whether the victim had suffered an anoxic event, the doctor agreed
that “at some point if you cut off oxygen to somebody’s brain, brain
cells will die.” And once those brain cells die, they are “gone
forever.”
¶ 17 Viewing this evidence in the light most favorable to the
prosecution, there was substantial and sufficient evidence from
which the jury could reasonably find beyond a reasonable doubt
that Tryels inflicted serious bodily injury on the victim.
¶ 18 Even so, Tryels insists that the evidence showed only that the
victim “could have lost one or more brain cells,” not that she
suffered any actual injury from the strangulation. That’s not
correct. As just detailed, substantial evidence showed that the
victim suffered anoxia. And both the forensic nurse examiner and
the emergency room doctor confirmed that anoxia results in the
permanent loss of brain cells. Neither testified that anoxia “could
have resulted” in the loss of brain cells. Thus, the evidence was not
speculative; it was tethered directly to the victim’s actual injury —
the lack of oxygen to her brain resulting in the permanent loss of
6 brain cells. And Tryels doesn’t dispute that the brain is an “organ
of the body.” § 18-1-901(3)(p).3
¶ 19 People v. Vigil, 2021 CO 46, and Stroup v. People, 656 P.2d 680
(Colo. 1982), on which Tryels relies, don’t change anything. While
Vigil and Stroup conclude that evidence about the risk generally
associated with the type of conduct or injury is insufficient to prove
a serious bodily injury, both agree that “the facts of the actual
injury control” the serious bodily injury determination. Vigil, ¶ 33;
see Stroup, 656 P.2d at 685. And here the victim’s actual injury
supports the jury’s serious bodily injury finding.
¶ 20 To the extent Tryels alternatively asks us to draw different
inferences from the negative CT scan, the lack of expert testimony
about the victim’s epilepsy, or the lack of more specific evidence of
brain impairment — such as evidence about the victim’s memory
before and after the strangulation — we won’t do that. The jury
weighs the evidence and resolves evidentiary conflicts or
3 Because we conclude that the evidence was substantial and
sufficient to show that the victim suffered an anoxic event, we don’t address Tryels’ argument challenging the forensic nurse examiner’s determination that the victim suffered a “probable concussion,” which the nurse also concluded was a serious bodily injury.
7 inconsistencies.4 See People v. Perez, 2016 CO 12, ¶ 25 (in
conducting a sufficiency analysis, we do not “serve as a thirteenth
juror or invade the province of the jury” (citation omitted)).
¶ 21 For these reasons, we conclude that sufficient evidence
supported the jury’s finding that Tryels caused serious bodily
injury.
III. Witness Exclusion
¶ 22 Tryels next contends that reversal is required because the
district court excluded a defense witness — Amari Parks — from
testifying at trial as a sanction for defense counsel’s failure to timely
endorse Parks under Crim. P. 16. We aren’t persuaded.
¶ 23 Before trial, the parties knew that Parks was possibly the
woman who entered the victim’s apartment with Tryels and
assaulted the victim’s sister. But defense counsel did not endorse
Parks as a defense witness.
4 And indeed, that’s what defense counsel argued in closing
argument. He specifically pointed the jury to the doctor’s testimony about the negative CT scan and the doctor’s lack of serious bodily injury finding and argued that the jury should credit the testimony of the doctor over that of the forensic nurse examiner.
8 ¶ 24 On the third day of trial, defense counsel informed the court
that Parks was present, and that he intended to call her as a
witness. He explained that she would testify that she was not
present when Tryels strangled the victim and that she did not
assault the victim’s sister.
¶ 25 The prosecution objected, arguing that the endorsement was
untimely, unfair, and irrelevant, and asked the court to preclude
Parks.
¶ 26 The court found that the defense had been aware for several
months that Parks would testify she wasn’t with Tryels in the
victim’s apartment, the defense could have timely endorsed her,
and her testimony had limited relevance. The court was also
concerned about Parks’ possible Fifth Amendment rights (since the
victim’s sister raised the possibility that Parks was the woman who
had assaulted the sister). Considering all this, the court barred the
defense from calling Parks to testify.
¶ 27 Rule 16 governs discovery in criminal cases. People v. Dye,
2024 CO 2, ¶ 36. For felony charges, it requires the defense to
disclose no less than thirty-five days before trial “the names and
9 addresses of persons whom the defense intends to call as witnesses
at trial.” Crim. P. 16(II)(c).
¶ 28 When — as here — the defense doesn’t timely disclose a trial
witness, a district court has broad discretion to determine an
appropriate sanction. See People v. Whittington, 2024 CO 65, ¶ 17.
A court abuses its discretion when its ruling is manifestly arbitrary,
unreasonable, or unfair, or when it misapplies the law. People v.
Knisley, 2022 CO 59, ¶ 21.
¶ 29 To craft an appropriate discovery sanction, the court must
consider (1) the reason for and degree of culpability associated with
the discovery violation; (2) any prejudice to the other party;
(3) whether any circumstances mitigate such prejudice;
(4) reasonable and less drastic alternatives to exclusion; and
(5) other relevant facts. People v. Tippet, 2023 CO 61, ¶ 37.
¶ 30 Though the court didn’t expressly list the Tippet factors in its
discussion regarding the defense’s failure to comply with Rule 16,
we conclude that it considered the appropriate factors when it
barred Parks from testifying. The court highlighted that the defense
had known about Parks for many months and knew the substance
of her testimony, yet “the proper endorsement was not made.” It
10 also noted that any testimony that Parks was not present during
the charged crimes was minimally relevant. Beyond that, implicitly
contemplating less drastic alternatives to exclusion, the court
expressed concern that Parks was “a witness who probably need[ed]
counsel” to address her Fifth Amendment rights. And it observed
that “had [Parks] been properly endorsed, we could have addressed
this at the beginning of trial.” But given the late endorsement, the
court was unable to secure counsel to advise Parks in the middle of
trial.
¶ 31 Under these circumstances, we cannot conclude that the court
abused its discretion by barring an unendorsed witness long known
to the defense. See People v. Dist. Ct., 808 P.2d 831, 838 (Colo.
1991) (an appellate court defers to a district court’s factual finding
regarding the nature of a discovery violation if it is supported by
competent evidence in the record).
¶ 32 Even had the court erred — and we don’t think it did — Parks’
proposed testimony that she wasn’t at the victim’s apartment and
thus could not have witnessed any of the events at issue added
nothing to Tryels’ defense (which was general denial). Excluding
11 that testimony did not affect the trial’s outcome under any standard
of reversal.
IV. Merger
¶ 33 Tryels argues that first degree trespass is a lesser included
offense of first degree burglary, and, accordingly, that his trespass
conviction should merge into his burglary conviction. See Reyna-
Abarca v. People, 2017 CO 15, ¶ 64 (discussing lesser included
offenses). The People agree, and under the facts presented here, so
do we. See People v. Miller, 2024 COA 66, ¶ 70 (“[F]irst degree
criminal trespass is a lesser included offense of first degree
burglary . . . .”); see also Whiteaker v. People, 2024 CO 25, ¶ 20
(holding that first degree criminal trespass is a lesser included
offense of second degree burglary). We therefore reverse and
remand to the district court to merge the trespass and burglary
convictions. .
V. Disposition
¶ 34 The portion of the judgment showing separate convictions for
trespass and burglary is reversed. We remand to the district court
to merge the trespass and burglary convictions and amend the
mittimus accordingly. The judgment is otherwise affirmed.
