APPEAL FROM THE CIRCUIT COURT OF LACLEDE COUNTY Honorable Aaron G. Koeppen, Circuit Judge AFFIRMED Martin Priest (Movant) appeals from an order denying his amended Rule 29.15 motion to set aside his conviction for first-degree murder for strangling and killing a 15- year-old victim (Victim) in 1984. See § 565.003 RSMo (1978). 1 Because the motion court’s decision to deny relief after an evidentiary hearing was not clearly erroneous, we affirm.

1

The crime of first-degree murder under the criminal code in place at the time of the alleged crime, § 565.003 RSMo (1978), was similar to what would be the crime of second-degree felony murder today, pursuant to § 565.021 RSMo (2016). See State v. Priest, 585 S.W.3d 397, 398 n.1 (Mo. App. 2019). All references to rules are to Missouri Court Rules (2024).

Movant bore the burden of proving the grounds asserted in his post-conviction motion by a preponderance of the evidence. See Rule 29.15(i); McLaughlin v. State, 378 S.W.3d 328, 337 (Mo. banc 2012). Our review of the denial of a Rule 29.15 motion is limited to determining whether the motion court’s findings of fact and conclusions of law are “clearly erroneous.” Rule 29.15(k); Flaherty v. State, 694 S.W.3d 413, 416-17 (Mo. banc 2024).

[A]n appellate court can overrule the motion court’s judgment after an evidentiary hearing if it is based on: (1) a mistake of law, (2) a factual finding for which there was insufficient evidence, or (3) a factual finding for which there was sufficient evidence but which the appellate court, nevertheless, finds was clearly erroneous, i.e., the appellate court on the whole of the evidence is left with a definite and firm conviction that a mistake has been committed.

Flaherty, 694 S.W.3d at 418 (internal footnote omitted).

“This Court presumes that the motion court’s findings are correct.” Barton v. State, 432 S.W.3d 741, 748 (Mo. banc 2014). An appellate court also “defers to the motion court’s superior opportunity to judge the credibility of witnesses.” Shockley v. State, 579 S.W.3d 881, 892 (Mo. banc 2019) (internal quotation marks and citations omitted). The motion court is “entitled to believe all, part, or none of the evidence presented at the post-conviction hearing.” State v. Hunter, 840 S.W.2d 850, 863 (Mo. banc 1992). The evidence at trial is viewed in the light most favorable to the verdict. State v. Lammers, 479 S.W.3d 624, 632 (Mo. banc 2016); State v. Smith, 679 S.W.3d 599, 601 (Mo. App. 2023). The following summary of facts has been prepared in accordance with these principles.

Movant was charged by a second-amended information with first-degree murder for causing Victim’s death by strangling her, and that he did so while raping her, or after the rape to prevent detection. The charge arose from events that occurred in May 1984, when Victim disappeared. Over 30 years later, Movant’s nephew (Nephew) came forward and

implicated Movant. Following a jury trial in October 2018, the jury found Movant guilty as charged. Viewing the evidence favorably to the jury’s verdict, as we must, the following facts were adduced at trial.

In May 1984, Victim was 15 years old and lived in Eldon, Missouri, with her mother (Mother) and older brother (Brother). At the time, Mother had been dating Movant for a few months.

Nephew was then 13 years old. He was nearly six feet tall, had “scraggly” hair, and was described as looking Native American. Nephew was living in his maternal grandmother’s home in Eldon, Missouri. His mother, older brother, and younger siblings had also lived in the home periodically, before moving to a trailer home in Osage Beach, Missouri. According to Nephew, his mother “jumped around,” and moved in and out of his grandmother’s home “on several different occasions.” Nephew and his older brother previously lived in Wichita, Kansas, with their paternal grandparents. Nephew had been enrolled in school in Eldon, but he “hardly ever went to school[.]” Nephew also knew Victim. She befriended Nephew after she helped Nephew and his older brother avoid a fight with other teenagers after school.

In the early morning of May 16, 1984, Movant borrowed Brother’s car, a two-door blue Buick Skylark, because Victim had an accident in Movant’s vehicle the previous day. Movant first drove to Nephew’s grandmother’s home where Nephew was staying. Movant picked up Nephew and they drove toward the high school in Eldon, where Victim was a student.

Victim was with her friend (Friend) smoking a cigarette in front of the school before school started. Around 7:40-7:45 a.m., Movant and Nephew drove up in a blue car. Movant told Nephew to ask Victim to come with them and skip school and motioned for Victim to

approach the car. Victim told Friend she would be right back and walked to the car. Victim seemed nervous, but later told Nephew that she decided to get into the car because Nephew was also in it. Nephew stepped out of the car to let Victim into the back seat, and the car drove away. After driving for a little while, Movant stopped at a gas station to buy a drink.

After returning from the gas station, Movant drove out of town and turned onto a gravel road that Nephew did not recognize. Victim became uneasy and told Movant that she wanted to go back to school. Movant pulled over and said that he needed to go to the restroom. Victim became more uneasy and continued begging Movant to take her back to school. Movant exited the vehicle and looked around.

Victim then told Nephew that she needed to use the restroom, and Victim and Nephew exited the vehicle. As soon as she got out of the car, Victim fled. Movant screamed at Nephew, “What the hell’s wrong with her? … Go get her!” Nephew chased after Victim, who eventually stopped after hopping a fence. Nephew asked Victim what was wrong, and, frightened, Victim told him, “I’m not getting back in the car.” Nephew calmed Victim down and convinced her to return to the car.

Once they returned, Movant told Nephew to get in the back seat, and Victim sat in the front seat. Movant proceeded down the gravel road and began arguing with Victim about Movant’s wrecked vehicle, telling her, “don’t try to lie to me.” Victim responded that if Movant had a problem, they could discuss it with Mother. Movant turned the car around before stopping again.

Movant turned to Nephew and informed him that he knew Nephew and Victim were in a relationship and suggested that Nephew and Victim have sex in the back seat of the car while he watched. Because Nephew had been groomed by family members to have sex in

front of them, he felt that he needed to do what Movant asked. Victim also seemed to feel that she needed to obey Movant to get through the situation.

After Victim and Nephew had sex, Movant told Victim to get back in the front seat.

Once Victim was in the front seat, Movant dropped an item onto the floorboard and asked Victim to pick it up. As Victim was reaching down for the item, Movant struck Victim on the back of the head with a wrench. When Nephew tried to intervene, Movant hit him. Nephew cowered behind the seat to avoid being hit again.

Movant then raped Victim while Victim screamed, “no,” and he strangled her to death.

After murdering Victim, Movant drove Nephew and Victim’s body to Nephew’s mother’s trailer home. As they were driving, Movant told Nephew that if he ever told anyone what happened, Nephew would be in as much trouble as Movant. Then, Movant and Nephew carried Victim’s body into the trailer and into Nephew’s sisters’ bedroom. Nephew’s mother, older brother, and younger siblings were all home. Movant tried to keep everyone out of the bedroom, but Nephew’s older, then 14-year-old brother was able to get inside and saw Victim’s body. Nephew’s mother also saw Victim’s body.
