Robison family murders
Summary
The Robison family murders, also referred to as the Good Hart murders, were the mass murders of Richard Robison, his wife Shirley Robison (née Fulton), and their four children; Ritchie, Gary, Randy, and Susan on June 25, 1968. The upper-middle-class family from the metropolitan Detroit area of Lathrup Village, Michigan, were shot and killed while vacationing in their Lake Michigan cottage just north of Good Hart, Michigan, near the Straits of Mackinac.

Bloody footprints on the floor led investigators to conclude that one person committed the murders. The bodies were not discovered for 27 days and conditions at the murder scene resulted in advanced decomposition of the bodies.
By the second week of the investigation, which had begun on Monday, July 22, 1968, the Michigan State Police and the Emmet County authorities suspected Richard Robison's employee Joseph R. Scolaro III, aged 30. He had not been seen or heard from for more than twelve hours on the day of the murders, and his alibis for that time period all proved invalid. He had also purchased both of the murder weapons determined by police forensic tests to have been used in the Robison family murders, specifically, a .
