Lachrica Denise Jefferson, 22, was found dead January 30, 1988, in the 2000 block of West 102nd Place in the Westmont area of Los Angeles County. Her body was discovered partially clothed, a detail reported in connection with a series of similar killings in South Los Angeles during the 1980s.

Jefferson is believed to be the seventh victim in a string of murders attributed to the killer later dubbed the Grim Sleeper. The suspect targeted vulnerable women, often chronic drug users or street sex workers, and commonly used a small-caliber handgun, leaving bodies in alleys or other secluded locations. Investigators say the chaotic environment of South Los Angeles in the 1980s hampered the early probe.

Years later, DNA evidence was used to link the same suspect to multiple murders, including Jefferson’s. Anyone with information about Jefferson, where she lived or spent time in the late 1980s, is asked to come forward.
