Mary Lou Pratt, 33, of Dallas was murdered on December 13, 1990, in the Oak Cliff neighborhood. Her killing was later tied into a string of murders that targeted sex workers in late 1980s and early 1990s Dallas, a pattern marked by the removal of victims’ eyes.

Charles Frederick Albright, known as the Eyeball Killer, became the prime suspect in Pratt’s death. Investigators used evidence from Pratt’s case at Albright’s trial; although prosecutors never filed formal charges against him for Pratt’s murder, his trial produced a conviction connected to at least one other victim and a sentence of five years to life that referenced evidence from Pratt’s case.

Pratt’s death remains a stark example of the peril faced by sex workers in that period and of how one investigation linked multiple killings. If anyone knew Mary Lou Pratt, her routines, associates, or saw anything in Oak Cliff around December 13, 1990, share what can help complete the record.
