A home invasion in the early morning hours of May 22, 2023, left 57-year-old Darin Gosejohan dead at his residence in the 1600 block of Country Acres Drive in Saint Peters, Missouri. Surveillance footage inside the house captured a large figure coming up the stairs with a flashlight in one hand and a small revolver in the other. The intruder confronted Gosejohan’s 13-year-old daughter, ordered her downstairs, then went to the master bedroom where a confrontation and gunfire were recorded. The teenage girl tried to flee but could not unlock the front door and retreated upstairs. Gosejohan’s 45-year-old wife and the daughter sustained gunshot wounds and survived after transport to a hospital; Darin Gosejohan was found dead when police arrived.

Investigators identified a suspect from witnesses and video; Darin’s sister identified the shooter as her boyfriend, 51-year-old Christopher L. Harper of St. Louis, and linked the vehicle seen on footage to her. The alleged motive involves a long-running family dispute over finances after Gosejohan was granted conservatorship over his parents. Harper was arrested and charged with first-degree murder, first-degree burglary, first-degree assault and armed criminal action and was being held without bond.

Does anyone have information about the night of May 22, 2023, or about activity in that neighborhood around 1:40 a.m.?
