Nathan Douglas Davin pleaded guilty to intentional second-degree murder nearly 10 months after his mother was found dead in her recliner.

DULUTH, Minn. — A Minnesota man who admitted killing his 74-year-old mother inside the Duluth home they shared has been sentenced to 261 months in prison, bringing the criminal case to a close nearly a year after police found the woman dead in a living room recliner. Nathan Douglas Davin, 47, received the sentence for second-degree murder with intent, but not premeditation.

Judge Leslie E. Beiers imposed the sentence in St. Louis County District Court after Davin pleaded guilty June 8 to killing his mother, Maedean Davin, on Aug. 16, 2025. The 261-month term equals 21 years and nine months. The St. Louis County Attorney’s Office said the punishment was within the presumed guideline range for the offense. Authorities had initially arrested Davin hours after the killing, but the case moved through court for nearly 10 months before his guilty plea resolved the question of whether he would stand trial.

The sentencing marked the final major court step in a case that began with a report of a death on the 1500 block of North Ninth Avenue East. Duluth police said officers went to the residence on Aug. 16 and found Maedean Davin with an apparent gunshot wound. Her son was at the property and was arrested without incident. At that early stage, police described the investigation as active and released few additional details. Court filings and later reporting would provide a fuller account of what officers said they encountered inside the house and how investigators came to focus on Nathan Davin.

According to accounts of the criminal complaint, Davin had drawn attention outside the home before officers entered it. Wearing only boxer shorts and with blood visible on him, he went to a neighbor and indicated that someone had died. Another neighbor was also contacted and was told that his mother was dead. When police reached the property, Davin was on or near the front porch. He initially told officers that he had awakened and found his mother dead, according to the records described by news organizations that reviewed the charging documents.

Police then entered the home and found Maedean Davin seated in a living room recliner. The St. Louis County Attorney’s Office later said she had died from a serious gunshot wound to the face. Prosecutors said during the case that her position in the chair indicated she had been sleeping when she was shot. Authorities also documented evidence in the residence, including a spent casing and a bullet near the chair. Reports based on the complaint said several firearms and ammunition were found in the house, while a 9 mm pistol with what appeared to be blood on it was located in Nathan Davin’s bedroom.

Those discoveries became an important part of the investigation because Davin’s first account did not acknowledge responsibility. The County Attorney’s Office said he initially denied killing his mother after police took him to Duluth Police Department headquarters. While he later sat alone in an interview room, however, a recording captured him acknowledging that he had killed her, prosecutors said. That statement was described in the criminal complaint and later cited again by prosecutors when Davin entered his guilty plea. It gave investigators a recorded admission in addition to the physical evidence recovered from the residence.

Prosecutors charged Davin with second-degree murder with intent, not premeditated. That wording remained significant through the end of the case because it was the offense to which he ultimately pleaded guilty and for which Beiers sentenced him. At the time of the initial arrest, Davin was 46. He was 47 by the time the case reached its final court proceedings. Earlier court reporting said his prior record largely involved traffic matters and noted an older case in which a domestic-assault charge was dismissed after he pleaded guilty to interfering with an emergency call. Authorities did not point to a serious prior violent conviction when discussing the 2025 case.

The public record developed in stages. Duluth police first announced only that Maedean Davin had been found dead and that her son had been jailed pending a murder charge. The criminal complaint then supplied details about the scene, the firearms and Davin’s statements. Nearly 10 months later, the County Attorney’s Office announced that Davin had admitted in court that he murdered his mother at their Ninth Avenue East residence. His June 8 plea removed the need for a trial and shifted the case toward sentencing. He was sent to prison after the plea to begin serving what prosecutors described as the anticipated sentence while the formal sentencing hearing remained pending.

The sentence was imposed July 16, according to the County Attorney’s Office, which announced the outcome publicly the following day on its website. Prosecutors said Beiers ordered Davin to serve 261 months. Other reports on the hearing described the term as 21 years and nine months and noted that Davin would receive credit for time already served. The County Attorney’s Office credited the Duluth Police Department and the Minnesota Bureau of Criminal Apprehension for their work on the investigation. Assistant St. Louis County Attorney Kirstyn Oye and Duluth Criminal Division Head Nathaniel Stumme prosecuted the case.

County Attorney Kim Maki said after sentencing that a prison term could not undo the loss suffered by Maedean Davin’s family and community. She said the sentence provided accountability and reflected the seriousness of the killing. The statement represented a shift from the guarded language officials used when the investigation was new, when Davin was an accused person and the facts still had to be proved in court. By July 2026, his guilty plea meant the central allegation no longer depended on a future trial: Davin had admitted the intentional second-degree murder, and a judge had imposed the resulting prison term.

Public reporting about the night of the killing also recorded unusual details inside the residence, including words and symbols spray-painted in parts of the house. Those details drew attention when charges were filed, but authorities did not publicly establish a motive for why Davin killed his mother. The absence of a confirmed motive remains one of the unresolved parts of the case. Prosecutors did not need to supply a speculative explanation for the sentencing announcement, instead focusing on Davin’s admission, the killing itself, the investigation and the punishment imposed by the court.

Maedean Davin had been described in community accounts as an educator who had worked at Summit School in Duluth. Her death was one of several homicides reported in the city in 2025, and local reporting at the time noted that domestic incidents had accounted for a substantial share of Duluth homicides in preceding years. In this case, however, officials kept their public statements centered on the individual victim, her son’s prosecution and the evidence developed after police entered the Ninth Avenue East home. The sentence now leaves Davin serving a term of more than two decades for the killing to which he pleaded guilty.

With the guilty plea entered and the 261-month sentence imposed, no trial remains scheduled in the murder case. The court resolution establishes Davin’s conviction for second-degree murder with intent, not premeditated, while the publicly available accounts still do not identify a confirmed motive for the Aug. 16, 2025, killing.
