The People of the State of Colorado,

Dong Ngoc Phan,

Defendant-Appellant.

JUDGMENT AFFIRMED

Division II Opinion by JUDGE MEIRINK Fox and Brown, JJ., concur

NOT PUBLISHED PURSUANT TO C.A.R. 35(e) Announced November 26, 2025

Philip J. Weiser, Attorney General, Majid Yazdi, Senior Assistant Attorney General, Denver, Colorado, for Plaintiff-Appellee

Megan A. Ring, Colorado State Public Defender, Jeffrey A. Wermer, Deputy State Public Defender, Denver, Colorado, for Defendant-Appellant ¶1 Defendant, Dong Ngoc Phan, appeals his convictions of

attempted second degree murder and first degree assault. We

affirm.

I. Background

¶2 In May 2021, Phan called 911 to report a stabbing at the

apartment he shared with his girlfriend, T.H. Phan said to the 911

operator, “Help me. I stabbed my girlfriend.” The 911 operator

collected Phan’s address and heard Phan say, “Please help me.

Someone stabbed my . . . .” Phan started to say “wife” but went on

to say “girlfriend” instead.

¶3 When officers arrived on scene, T.H. and Phan were outside

the apartment building. T.H. was unconscious and bleeding, and

Phan was holding her. Phan had blood on the front of his jacket,

hands, and pants. Officers found drops of blood leading from the

couple’s location outside into their bedroom in their apartment,

where blood soaked the carpet. A crime scene analyst found a knife

in a laundry basket in a closet when they searched the apartment.

¶4 Police transported Phan to the police station and charged him

with attempted first degree murder and first degree assault.

Detective David Noble, the lead detective on the case, interviewed

1 Phan on the day of the incident in an interview room at the police

station. T.H. was transported to the hospital and underwent

surgery for five stab wounds — one on her stomach, one below her

breast, two on her lower back, and one on the back of her neck.

Noble interviewed T.H. five days later at the hospital.

¶5 At trial, Noble testified that T.H. stated the following during

their interview:

• T.H. decided to kill herself after Phan left the apartment.

She went to the kitchen, grabbed a knife, and walked back

into their bedroom.

• T.H. stabbed herself in the stomach. Phan then entered the

apartment, and the two struggled over the knife.

• During the struggle with Phan, T.H. somehow got stabbed

in the back of her neck and on her back left side near her

kidney. Phan was able to get the knife away and threw it

into a laundry basket.

• Phan “did not stab her.”

• T.H. thought about committing suicide three or four times

before, and she and Phan had made a pact to commit

suicide in the weeks before the incident.

2 ¶6 Shortly after the hospital interview, T.H. called Noble to amend

her prior statement. Noble testified that [T.H.]

changed [her statement] slightly to state that she tried to commit suicide to show her love for Mr. Phan. I clarified with her that she initially told me it was because she was depressed. And then she said it’s — due to Mr. Phan’s jealousy, she wanted to prove that she loved only him, along with her depression, on why she [attempted to] commit suicide.

¶7 T.H. later met with the prosecution’s investigator, Kate Battan,

and again changed her story. T.H. told Battan that she and Phan

“were arguing, and that she knocked over a humidifier that was

sitting on a table, out of anger and frustration. And then he started

kicking her. And then he grabbed a knife from underneath the

mattress. And then he started stabbing her.”

¶8 T.H.’s testimony at trial was generally consistent with what

she told Battan. T.H. testified that Phan was looking for his keys

when the two started to argue. T.H. said she pushed the humidifier

because she was upset, Phan kicked her, and she fell to the ground.

Then, Phan lifted the mattress on the bed, pulled out a knife, and

stabbed her. When asked why she gave Noble a different story, T.H.

said she was trying to protect Phan. She also testified that she gave

3 Battan a different version of events “[b]ecause that’s the truth. I

don’t want to lie.”

¶9 Following the presentation of evidence, the court discussed

jury instructions with the prosecutors and defense counsel. Phan

requested instructions on the affirmative defenses of intoxication,

heat of passion, and self-defense. The trial court denied the request

for a heat of passion instruction and a self-defense instruction, but

it granted the request for an intoxication instruction.

¶ 10 The jury ultimately found Phan guilty of attempted second

degree murder and first degree assault. Phan was sentenced to

eighteen years in the custody of the Department of Corrections.

Phan appeals his convictions.

II. Analysis

¶ 11 Phan argues that the trial court erred by (1) failing to correctly

instruct the jury on his affirmative defenses; (2) allowing Noble to

provide improper lay testimony because his testimony was based on

specialized knowledge, training, and his experience as a detective;

and (3) permitting Noble to improperly opine as to the truthfulness

of T.H.’s statements when he interviewed her. We disagree on all

counts.

4 A. Affirmative Defense Jury Instructions

¶ 12 Phan argues that the trial court erred by denying (1) a self-

defense jury instruction and (2) a use of physical force — special

relationship instruction. He contends that sufficient evidence

supported the instructions. We disagree.

1. The Trial Court Did Not Err by Denying Phan’s Request for a Self-Defense Jury Instruction

¶ 13 Phan contends that the trial court erred by refusing to provide

a jury instruction on self-defense because the testimony supported

an inference that Phan defended himself against T.H. We disagree.

a. Additional Applicable Facts

¶ 14 At trial, several law enforcement officers detailed what they

saw at the apartment or what Phan said to them shortly after the

incident.

• Agent Garret Compton was the first officer on the scene and

spoke with Phan. Phan told Compton that he and T.H. were

arguing. Phan became suspicious that another man was in

the apartment, “so he chose to barricade himself in the

bedroom” and “used a piece of furniture to block the door

and separate himself from [T.H.]”

5 • Detective Monique Gilstrap, one of the detectives who

executed the search warrant, testified that the TV stand in

the bedroom was pulled away from the wall, and officers

could not completely open the bedroom door because it was

as if “somebody was using it to try to block the door, to keep

that door closed.” Gilstrap also testified that the chain part

of the sliding lock on the door was on the floor behind the

door and not attached to the wall.

• Crime Scene Analyst Sheri Shimamoto testified that there

was what looked like a humidifier that came apart, among

other items, scattered on the floor.

¶ 15 T.H. gave the following trial testimony:1

• T.H. and Phan were in their apartment all day. They
