Mary Jane Thompson was found dead behind a warehouse on Irving Boulevard in the Stemmons Corridor in Dallas, Texas, United States on February 13, 1984. She was 21.
On February 11, 1984, Thompson took a bus to the Trinity Medical Clinic on then Industrial Boulevard in Dallas but the clinic was closed. In 2009, the boulevard was renamed Riverfront Boulevard.
On February 13, 1984, Thompson was found dead behind a warehouse on Irving Boulevard in the Stemmons Corridor in Dallas. She had been sexually assaulted and strangled with her own leg warmers.
Thompson’s assailant remained at large. The case went cold until it was reopened in 2009 when officials collected deoxyribonucleic acid samples during an autopsy.
A DNA profile for an unknown man was identified. However, it was never matched to a specific suspect so the case went cold again.
In 2018, Dallas Police Department detective Noe Camacho reopened the case and worked with the Dallas County district attorney’s Sexual Assault Kit Initiative team. In 2020, the Federal Bureau of Investigation joined the investigation task force.
Through a forensic genetic genealogy analysis, investigators identified Edward Morgan, 60, of Dallas as the suspect. On February 18, 2022, he was arrested and booked into the Dallas County jail.
Morgan was charged with capital murder. His bail has yet to be set.
“It is not every day we are able to solve a 38-year-old cold-case capital murder,” The Dallas Morning News quoted Dallas County assistant district attorney Leighton D’Antoni as saying. “It takes a singular dedication and authentic commitment to justice to see it through.”
