On the night of June 15, 2022, 25-year-old Ian Robert Stutterheim was killed in Flagstaff, Arizona, during a domestic violence incident that ended in a murder-suicide. Police were called to a residence on West Kaibab Lane about 9:39 p.m. after a trespassing report; an officer on scene heard a woman screaming inside the home.

Inside the house officers found Stutterheim and 31-year-old Tianna Guglielmo with multiple gunshot wounds. Stutterheim, described in reports as a friend and coworker of Guglielmo, died of his injuries. Authorities identified 31-year-old Kevin McManis, Guglielmo’s estranged husband, as the shooter; investigators say he had forced entry using a concrete block, shot Stutterheim and Guglielmo, then died of a self-inflicted gunshot wound. Guglielmo survived and was taken to hospital for treatment.

Does anyone have information about Stutterheim, his connections in Flagstaff, or details that could shed light on what led to that night?
