On the afternoon of Saturday, August 17, 2024, at approximately 4:00 p.m., Buffalo Police officers responded to a residence on the first block of Henrietta Avenue for a check the welfare call. Officers found the victim, 66-year-old Michael R. Fronczak, deceased in the basement of his home. The Erie County Medical Examiner’s Office ruled the death a homicide caused by blunt force trauma.
