Connor Steven Lotterman was 19 when he died after being struck by a bullet while at a house party in Tallmadge Township, near Grand Rapids, Michigan. The gathering on Second Avenue was underway late on May 9, 2025; about 11:11 p.m. an attendee upstairs found a rifle and fired several rounds through the bedroom floor. Multiple rounds penetrated the ceiling of the room below and one bullet struck Connor in the head. He was taken to a local hospital and died of his injuries on May 10, 2025.

Connor was an engineering student at Grand Valley State University and a graduate of Covenant Christian High School. Investigators from the Ottawa County Sheriff’s Office determined alcohol was a contributing factor. Westen Meulenberg, 20, of Jenison, Michigan, admitted he fired the weapon through the floor and acknowledged he had accidentally hit someone; the autopsy ruled the manner of death accidental and the cause gunshot wound to the head.

Does anyone who attended that party or knew Connor have information that could help clarify exactly what happened that night?
