On December 8, 1986, six people were killed in Oakland, California, when two people forced their way into the home of Barbara Mabrey and opened fire while several occupants slept. Among the dead was 22-year-old Darnell Mabrey; other victims included his siblings Dellane and Sean Mabrey, Dellane’s daughter Valencia Morgan, and family friends Katherine Walker and her son Duane. Barbara Mabrey survived the attack.

The attackers were identified as David Esco Welch and his girlfriend Rita Lewis. The shooting has been tied to a violent, acrimonious relationship between Welch and Dellane Mabrey, including disputes after Dellane became pregnant and confrontations the night before the killings. Welch and Lewis were arrested within hours and later charged with multiple counts of first-degree murder and attempted murder. Reports say Welch was convicted of six counts of first-degree murder and received a death sentence that was affirmed on appeal.
