OPEN RECORDS SUMMARY :

On 08/11/2025, shortly after 8:45 p.m., Moorhead Police Department officers responded to an apartment at 2414 3rd Avenue North after a woman reported that 42-year-old Nathan Heiberg and his brother, 41-year-old Lucas Heiberg, had assaulted her. The woman told police that Nathan, with whom she had two children, had violated a protection/no-contact order by coming to the apartment. She alleged that Nathan punched her in the face and knocked her down and that both brothers assaulted and strangled her. She escaped from the apartment, but her children, ages 5 and 6, remained inside with the two men.
Moorhead officers went to the apartment and attempted to contact the brothers, but they did not respond. Police began forcing open the apartment door. According to the Minnesota Bureau of Criminal Apprehension investigation, a firearm was discharged from inside the apartment while officers were positioned in the hallway. Officers withdrew, evacuated neighboring apartments and requested the multi-agency Red River Valley SWAT Team.
Fargo Police Department Sgt. Michael Anderson, Sgt. Kyle Seehusen and Officer Tyler Seehusen responded as members of the Red River Valley SWAT Team. Police remained particularly concerned about the two young children inside the apartment. Body-camera footage later released by the Clay County Sheriff's Office documented the large multi-agency response, evacuation of neighboring apartments and SWAT entry into the residence.
According to the subsequent BCA investigation and Clay County Attorney's review, SWAT officers entered the apartment after the earlier gunfire. Police alleged that Nathan was armed with a revolver when Tyler Seehusen encountered him inside. Seehusen fired one round at Nathan, fatally wounding him. Officers removed the two children from the apartment unharmed and provided medical treatment to Nathan before an ambulance transported him to a hospital, where he died a short time later. Investigators recovered two firearms from the apartment.
The Minnesota Bureau of Criminal Apprehension conducted the independent investigation and reviewed body-camera recordings, physical evidence and the officers' actions. On 02/05/2026, Clay County Attorney Brian Melton announced that he had reviewed the BCA's 415-page investigative file and determined that the SWAT officers' use of deadly force was legally justified. The county attorney closed the criminal review without charges.
Tyler Seehusen had approximately eight years of law-enforcement experience at the time of the shooting.
