Sometime in the early morning of June 5th 1983, Douglas and Peggy Ryen, their 10 year old daughter Jessica, and 11 year old Christopher Hughes, a neighbor’s son who was spending the night with the Ryens, were brutally murdered in the Ryens’ bedroom at their home in Chino, California. The Ryens’ son Joshua, 8 years old, was critically wounded but survived the attack.

The Chino Hill Murders were initially described as “Manson-style”, referring to the 1969 murders of actress Sharon Tate and four others by followers of Charles Manson. This characterization started with detectives describing the scene to reporters. According to the coroner’s report, the victims sustained 140 wounds, 28 fractures, and 2 severed fingers using 3 weapons: a hatchet, a knife, and an icepick. A fourth weapon may have been used.
