Donna Lee Urban was 23 when she was last seen in Wilmington, Delaware, on February 7, 1983. Her NamUs listing is MP5607 and the Delaware River and Bay Authority Police are named as the investigating agency.

Donna stopped her car in the far-right northbound lane near the center of the Delaware Memorial Bridge, exited the vehicle and went over the bridge into the Delaware River. Officers and search-and-rescue teams searched through the night; her car was recovered on the bridge but no trace of Donna or her remains was found. Investigators reported no suicide note or clear evidence inside the vehicle. She was a 1977 graduate of Christiana High School and had ties to the Delaware Army National Guard.

Does anyone have memories of Donna, details about her life in the Wilmington area, or information about the bridge search that could help this long-standing inquiry?
