Diocela Espino-Simpson was 22 when she was found murdered in her Denver apartment at 1845 Grant Street on December 6, 1974. She had moved to Colorado from Texas two years earlier and worked as a seamstress at Gerry’s Sporting Goods; a roommate who also worked at the same store discovered her later that day after Diocela had left work early for unknown reasons.

The Denver Police Department investigated but the case produced no suspects or arrests and eventually went cold. The motive and circumstances of the killing remain unresolved and the identity of the person or persons responsible is still unknown.

Anyone who knew Diocela, lived near Grant Street in 1974, or has information about that day is asked to contact the Denver Police Department.
