The Robison family murders, also called the Good Hart murders, refers to the murders of Richard Robison, his wife Shirley Robison, and their four children, Ritchie, Gary, Randy, and Susan, in the summer of 1968.[1] The wealthy family from the Detroit area were murdered while vacationing in their summer cottage in Good Hart, Michigan. This case is still unsolved.[2][3]
Richard and Shirley Robison and their three sons were shot to death; their daughter Susan was bludgeoned with a claw hammer.[1] Shirley Robison was nude from the waist down when the bodies were discovered.[1]
Police suspected Richard Robison's business partner, Joseph Scolaro III, of the crimes, but Emmet County, Michigan prosecuting attorney Donald Noggle declined to bring charges.[1] Scolaro committed suicide in 1973, leaving behind a note in which he denied committing the murders.[1] Serial murderer John Norman Collins was also investigated regarding the murders; Collins attended Eastern Michigan University with Ritchie Robison, and was active during the period.[4] [5]
