A violent family confrontation on the evening of September 24, 2025, at a rural farm outside Alden, Minnesota, left 45-year-old Joshua Petersen dead. Joshua, who was in violation of active restraining orders, had been hiding in an outbuilding on his parents’ property when his mother, Shari Petersen, tried to enter. He assaulted her with a metal pipe and then attacked his father, Dave, and brother, Jason, with the same weapon. During the struggle Joshua reportedly took his brother to the ground and repeatedly punched him in the face.

Dave Petersen, 71, shot Joshua with a pistol after the assault escalated and he feared for his family’s safety. Deputies from the Freeborn County Sheriff’s Office found Joshua with two gunshot wounds to the chest at about 5:12 p.m.; Joshua was airlifted to a Rochester hospital and later died. Dave, Shari and Jason were treated for non-life-threatening injuries and have been cooperating with investigators. The Sheriff’s Office described Dave as the shooter and called the shooting defensive; the investigation has been forwarded to the Freeborn County Attorney’s Office for review and no arrests have been announced.

Years of family conflict and prior court-ordered protection for Joshua’s parents and brother are reported to have preceded the fatal confrontation. Does anyone have information about the family history or that night that could help clarify what happened?
