Latanga Lee Watts, 29, was found dead on March 18, 1987, in a grassy area near the Going Street pedestrian bridge on North Concord Avenue in Portland, Oregon. A mother of three, Watts was known to have been a victim of sex trafficking. Investigators determined her body had been moved after death, suggesting the killer attempted to conceal the crime.

The case went cold for decades until investigators linked Latanga’s murder to a series of similar slayings in Portland during the 1980s. Forensic testing in December 2014 recovered a mixture of DNA under her left fingernail; one profile matched a man who investigators suspect in multiple killings of women in that era. That connection helped tie her death to other victims and led to charges in the wider investigation.

Several legal and procedural issues affected the prosecution’s ability to present all evidence. Does anyone have memories of Latanga, her life in Portland, or information that could clarify what happened that night?
