Latisha Thomas was 21 when she was found dead behind a row of buildings in the 3200 block of 15th Place SE, Washington, D.C., on the morning of Monday, December 8, 1997. Neighbors reported an unconscious person in an alley; she was pronounced dead at the scene and the 7th District homicide squad opened an investigation.

Police classified the circumstances as suspicious and treated the case as a homicide, but the initial probe did not produce a publicly announced cause of death or identified suspects. The investigation stalled and the case grew cold. No arrests have been made and no persons of interest have been publicly named. A reward of up to $25,000 is being offered for information leading to an arrest and conviction.

If anyone knew Latisha, saw activity around 15th Place SE that morning, or has any information that could help, please come forward to the Metropolitan Police Department.
