Mary Katherine Lowe was 26 when her body was found on October 31, 1987, in an alley on the 8900 block of Western Avenue in the Gramercy Park area of Los Angeles. Her body had been left covered and abandoned, and the cause of death was a gunshot wound from a small-caliber firearm. Reports identify her as one of the victims in the series of murders attributed to the killer dubbed the Grim Sleeper.

The killings attributed to the Grim Sleeper spanned from 1985 to 2007 and targeted vulnerable women, including those involved in drug use or sex work; Mary Lowe is believed to have been the sixth victim in that series. Her murder remained unsolved for many years, and the long delay contributed to fear and distress in the community.

If anyone knew Mary Lowe, her routines, or has information about the Gramercy Park area in the late 1980s, please share what you know with investigators.
