Edward Morgan

Edward Morgan, 60, was arrested on February 18, 2022, for the February 1984 rape and murder of 21-year-old Mary Jane Thompson in Dallas, Texas.

Thompson’s body was found on February 13, 1984, behind a warehouse. She had been sexually assaulted and strangled with her own legwarmers. Thompson had moved to Dallas about 6 months before her death, and was working in a restaurant and a flower shop. She was last seen two days before her death, taking a bus to a medical clinic, which was closed when she arrived.

A DNA profile of the suspect was developed in 2009 from swabs preserved from Thompson’s autopsy. The investigation was a collaboration between the Dallas PD, the FBI, and the SAKI Cold Case Team of the District Attorneys Office. There is no official confirmation as to whether the FGG investigation was performed by the FBI’s Investigative Genealogy Unit. There is no information as yet on how the initial confirmation to Morgan was made.

Morgan is charged with capital murder. He is being held on bond in Dallas County. The charges against him are pending in the Dallas County District Criminal Court.
