Patricia Dunn, 37, was found dead on a loading dock of an abandoned property in Chicago’s South Side on September 21, 1993. Her partially clothed body had severe facial injuries concealed with a cloth, defensive wounds on her hands, and missing shoes. Investigators considered sexual assault, but the medical examiner reported no evidence of rape.

Dunn’s death later became linked by pattern and DNA to a series of murders of African American women found in similar circumstances in abandoned buildings or lots: faces covered, shoes missing, and in several cases sexual assault documented. The series culminated in the 2000 arrest of Andre Crawford, whose DNA matched evidence from multiple scenes and who confessed to numerous killings; he was convicted in 2009 and sentenced to life in prison.

What details about Patricia Dunn’s life or movements in Englewood might help clarify how she came to be at that abandoned loading dock?
