Debra Ronette Jackson was 29 when she was murdered on August 10, 1985. Her body was found in an alley near West Gage Avenue in the Vermont-Slauson area of Los Angeles; she had been shot three times in the chest. Ballistics later showed the same handgun used in her killing had been used in seven other murders, and her death became linked to a series of killings attributed to a perpetrator called the Grim Sleeper.

Investigators struggled for years to connect these cases amid a citywide spike in crime and cocaine-related violence. A major development came on July 7, 2010, when authorities arrested Lonnie David Franklin Jr., a 57-year-old South Los Angeles resident and former city trash collector and LAPD vehicle mechanic, charging him with ten counts of murder, including Jackson’s, plus one attempted murder. His trial began in February 2016 and featured detailed autopsy testimony about Jackson and other victims.
