On August 19, 1980, Keith and Patrice Harrington were found brutally murdered in the bedroom of their Cockleshell Drive home in the gated Niguel Shores community of Dana Point, California. The couple, three months into their marriage, were discovered by Keith’s father, Roger Harrington, on a bed drenched in blood. Both victims had been bludgeoned to death; Patrice, a 28-year-old pediatric trauma nurse, had also been raped. Reports say the victims had been bound at their wrists and ankles, but the ligatures and the murder weapon were missing.

Investigators later matched semen from the scene to two other unsolved Orange County murders, linking the Harrington slayings to a serial offender active in California in the 1970s and 1980s. The case remained cold for decades until forensic advances and investigative genetic genealogy produced an arrest in 2018. Did anyone in Niguel Shores or the surrounding area have contact with the Harringtons in the weeks before August 19, 1980?
