SYLLABUS

Under the corpus delicti statute, Minnesota Statutes section 634.03 (2024), when a district court correctly denies a defendant’s motion for judgment of acquittal based on its determination that the trial evidence is sufficient to be presented to the jury because evidence independent of the defendant’s confession reasonably tends to prove that the defendant committed the charged offense, the court acts within its discretion by declining

to instruct the jury that a confession of the defendant shall not be sufficient to warrant conviction without evidence that the offense charged has been committed.

OPINION

EDE, Judge In this appeal from a final judgment of conviction for misdemeanor domestic assault, appellant argues: (1) that the district court erred by denying his motion for judgment of acquittal because, under the corpus delicti statute, Minnesota Statutes section 634.03 (2024), the state did not introduce evidence independent of his confession that reasonably tends to prove that he committed the charged offense; and, in the alternative, (2) that he is entitled to a new trial because the court abused its discretion by declining to instruct the jury pursuant to the corpus delicti statute that a confession of the defendant shall not be sufficient to warrant conviction without evidence that the offense charged has been committed. We conclude that the district court correctly denied appellant’s motion for judgment of acquittal based on its determination that, under the corpus delicti statute, the trial evidence was sufficient to be presented to the jury because evidence independent of his confession reasonably tends to prove that he committed the charged offense. And because the district court did not err in this determination, we also conclude that the court acted within its discretion in denying the requested jury instruction. We therefore affirm.

FACTS

Respondent State of Minnesota charged appellant Johnathon Brock Mattson-McCarty with misdemeanor domestic assault, in violation of Minnesota Statutes section 609.2242, subdivision 1(2) (2022). The matter proceeded to a jury trial, at which the state introduced the testimony of a law enforcement officer who responded to the underlying incident. The district court also received two exhibits—an audio recording of a 911 call about the incident and a video recording from the responding officer’s body-worn camera. Consistent with applicable law, the following factual summary of the trial evidence is presented in the light most favorable to the state. 1 In November 2023, an individual called 911 from a restaurant parking lot, reporting:

[I]t seems like there is a domestic dispute in one of the cars next to me . . . . I’m not hearing anything. I’m just watching them scream at each other and the guy keeps moving closer and having like big arm movements towards the other person in the car.

The 911 caller described the people involved in the incident as being in a “black Ram truck.”

The officer responded to the scene, observed an individual later identified as Mattson-McCarty walking away from a black Ram truck, and told him to stop and return, which Mattson-McCarty did. After asking what was going on, Mattson-McCarty stated that he was asking the mother of his child to leave his vehicle. The officer turned his

1 See Allwine v. State, 994 N.W.2d 528, 537 (Minn. 2023) (stating that, in reviewing a district court’s decision on a motion for judgment of acquittal, appellate courts “view all the evidence presented and draw any inferences in favor of the State”).

attention to a woman sitting in the front passenger seat of the black Ram truck and told her to remain in place.

Mattson-McCarty continued explaining to the officer that he had just found out that the woman “was talking to someone else” and that he did not want her in his life or in his truck. Speaking from the front passenger seat of the truck, the woman said to the officer, “I guess it’s fine.” After telling the woman that his partner was on the way to help sort things out, the officer asked Mattson-McCarty if the situation had become “physical at all.” In response, Mattson-McCarty twice admitted to the officer that he had slapped the woman. 2 Upon further questioning as to why he had done so, Mattson-McCarty stated that he “didn’t know,” that “it just happened in the moment,” and that the fight occurred because he “looked on her phone because [he] saw something.” When the officer explained to Mattson-McCarty that he had been dispatched to the scene because someone had reported hearing Mattson-McCarty and the woman “yelling and screaming at each other,” Mattson- McCarty said that he “kind of knew that was coming” and decided that he “need[ed] to leave this situation somehow . . . but it was too late,” as that was when the officer had arrived. The body-worn-camera footage introduced at trial depicts the woman providing the officer with her name, affirming that the child she shares with Mattson-McCarty was at her residence, and telling the officer that the child was “fine.”

2 Mattson-McCarty also nodded in response to the officer’s subsequent questions about the assault, in which the officer asked if it was “just the one time”—i.e., “the one slap”—and whether it occurred “out of frustration.”

After the state introduced the foregoing trial evidence and rested its case-in-chief, Mattson-McCarty moved for judgment of acquittal. Mattson-McCarty argued, among other things, that the state had not presented sufficient independent evidence to corroborate his confession, as required by the corpus delicti statute. The prosecutor countered that the state had introduced such evidence, including the 911 call, Mattson-McCarty’s non-confessional statements, and the “totality of the circumstances.” The district court denied Mattson- McCarty’s motion, ruling that “there [was] enough to go to the jury” based on the audio recording of the 911 call and the officer’s testimony about his investigation.

Following the district court’s denial of Mattson-McCarty’s motion for judgment of acquittal, defense counsel requested that the court instruct the jury under the first sentence of the corpus delicti statute, proposing that the instruction state: “A confession of the defendant shall not be sufficient to warrant conviction without evidence that the offense charged has been committed.” See Minn. Stat. § 634.04. The state at first opposed this request in its entirety, asserting that a corpus delicti question requires “a determination for the judge to make,” that the district court had “made that ruling,” and that it was inappropriate to allow the jury to decide the issue. Although the state later conditionally agreed to the requested instruction—subject to the inclusion of additional language— Mattson-McCarty objected to part of the state’s counter-proposal. The district court ultimately denied Mattson-McCarty’s request, reasoning that the corpus delicti issue was for the court to decide, not the jury, and that the court had already ruled on the matter.

Nevertheless, the district court allowed Mattson-McCarty to argue in closing—
