Opinion

In the Missouri Court of Appeals Eastern District DIVISION TWO

STATE OF MISSOURI, ) No. ED112290 ) Respondent, ) Appeal from the Circuit Court ) of Washington County vs. ) Cause No. 21WA-CR00751-01 ) MARK J. MATLOCK, ) Honorable Wendy L. Wexler Horn ) Appellant. ) FILED: April 29, 2025

Opinion

Mark J. Matlock (Matlock) appeals from the trial court’s judgment following jury

convictions on voluntary manslaughter, armed criminal action, and unlawful use of a weapon for

shooting Victim. Matlock raises two points on appeal. Point One argues the trial court abused

its discretion in admitting double-hearsay testimony from Victim’s Aunt about Victim’s

Grandmother purportedly threatening Victim, which Matlock argues impaired his justification

defense that he shot Victim to protect Grandmother. 1 Point Two asserts the trial court abused its

discretion in excluding testimony purporting to demonstrate Victim’s violent and turbulent

nature, which Matlock contends prejudiced his ability to prove Victim was the initial aggressor

during the deadly encounter. We deny Point One because Matlock fails to show how the

admission of the double-hearsay testimony resulted in outcome-determinative prejudice. We

1 Names are redacted pursuant to § 509.520, RSMo (Cum. Supp. 2023). deny Point Two because Matlock did not preserve the issue for appeal. Accordingly, we affirm

the trial court’s judgment.

Background

The following evidence is presented in the light most favorable to the verdict: 2

The State charged Matlock with first-degree murder, armed criminal action, and unlawful

use of a weapon arising out of an incident on December 29, 2021, in which Matlock shot and

killed Victim following an argument between Victim, Grandmother, and Matlock.

Victim had moved in with his Grandmother and his Grandmother’s long-time domestic

partner, Matlock, after the birth of Victim’s Daughter in 2019. Grandmother helped take care of

Daughter despite frequent friction between Victim, Matlock, and herself. On December 29,

2021, Victim and Grandmother got into an argument when he slept in late and refused to help out

around the house as requested. Grandmother asked Victim to leave, then retreated to her

bedroom and closed the door.

Matlock approached Victim and also asked him to leave. Instead of doing as requested,

Victim grabbed a machinist hammer and began to beat on Grandmother’s bedroom door.

Matlock pulled out a gun and shot Victim four times. One of Matlock’s first shots left Victim

“paralyzed” from the middle of his chest downward. While Victim was on the ground, Matlock

shot him in the right side of his head and killed him. Grandmother and Matlock did not call the

police. Upon hearing the news of Victim’s death, other members of Victim’s family arrived at

the scene. Victim’s Brother chased Matlock away from the home and, once the police arrived,

Matlock turned himself in.

2 State v. Scott, 676 S.W.3d 336, 339 (Mo. App. E.D. 2023) (internal citation omitted).

2 Following Matlock’s arrest and charges, the case proceeded to trial, where Matlock

asserted the justification of defense of another. 3 Matlock testified in his own defense that he shot

Victim to protect Grandmother because he feared Victim was threatening Grandmother’s life.

Grandmother also testified in Matlock’s defense. At trial, Matlock unsuccessfully attempted to

elicit testimony from Grandmother about an incident of alleged violence by Victim against

Victim’s Girlfriend during Thanksgiving of 2021. Initially, Defense Counsel asked

Grandmother whether that Thanksgiving was “a pleasant time,” and the State objected on

relevance grounds. Defense Counsel informed the trial court that the sought-after testimony

would go to Victim’s violent nature, and the trial court allowed Defense Counsel to proceed.

Defense Counsel: So when you arrived at the home in Union who all was there?

Grandmother: [G]irlfriend and his [G]irlfriend’s son and his [D]aughter.

Defense Counsel: Okay. And you mentioned that wasn’t a good time, and why is that?

Grandmother: [Victim and Girlfriend] were fighting.

Defense Counsel: Okay. How did you know they were fighting?

Grandmother: They were fussing and arguing and there was bruises on both of them.

The State renewed its relevance objection, arguing that Grandmother did not know where

the bruises came from and that the testimony pertaining to “fussing and arguing” did not show

Victim’s violent nature. The trial court allowed Defense Counsel to ask more specific questions.

Defense Counsel asked Grandmother: “And you had mentioned that there had been some

fighting between [Victim] and [Girlfriend]; is that correct?” The State again objected on the

grounds that the question lacked relevance and was also argumentative. Defense Counsel

3 Matlock did not present a claim of self-defense to the jury.

3 explained to the trial court that he was attempting to ask Grandmother about a fight she

observed. The trial court ruled that Defense Counsel could ask if Grandmother observed any

other form of “fussing and arguing” but was limited to her response. When Defense Counsel

asked Grandmother whether she observed any other form of “fussing and arguing,” Grandmother

said no. Defense Counsel did not ask her any further questions about Thanksgiving of 2021.

Victim’s Aunt testified on behalf of the State. The State elicited testimony from Aunt

about what Victim told her about an argument he had with Grandmother four days before the

offense. Specifically, Aunt testified she drove Victim to Grandmother and Matlock’s home so he

could retrieve some things. Aunt said she waited in the car, and Victim returned after only a few

minutes clearly upset. Aunt was about to testify about what Victim told her when Matlock

objected on hearsay grounds. The State countered the testimony would be admissible under

three hearsay exceptions: (1) dying declaration, (2) forfeiture by wrongdoing and (3) state of

mind. The trial court overruled Matlock’s objection. The State’s examination of Aunt

continued:

State: Okay. So when [Victim] exited the house and then approached you, what did he tell you?

Aunt: [Victim] got back in the car. I asked him what was going on because he was cussing and raving. He said, “The bitch won’t let me take my kid.” And I said, “Well what do you mean?” And he said, “[Grandmother]’s been trying to get me to sign over custody of [Daughter], and I told her it would be over my dead body.”

Matlock renewed his objection on hearsay grounds, which the trial court again overruled.

Aunt proceeded to testify that Victim told her that Grandmother told him “to sign over custody

of [Daughter], and [Victim] said it would be over his dead body, and [Grandmother] told him

that that could be arranged.” Aunt added that Victim said Grandmother had threatened him

4 before and that he thought Grandmother was going to kill him in his sleep. The State later

mentioned Aunt’s testimony in closing argument.

The State called more of Victim’s family to prove Matlock had a gun that he planned to

use to kill Victim. Specifically, both Victim’s Cousin and Victim’s other aunt (Aunt-by-Blood)

asked Matlock why he had a gun, and Matlock responded he was going to kill Victim. Aunt-by-

Blood observed Matlock carrying a gun two weeks before Victim’s death. Victim’s Brother also

testified that Matlock had a gun one or two months before Victim’s death. Furthermore, Brother
