DALLAS (AP) — Investigators have arrested a 60-year-old Dallas man on capital murder charges in the 1984 murder of a 21-year-old woman after linking him to the crime through genealogy databases, officials said Friday. prosecutors.
Edward Morgan has been arrested in the murder of Mary Jane Thompson, who was also sexually assaulted, the Dallas County District Attorney’s Office said.
Morgan was being held Friday at the Dallas County Jail. Bond was not yet listed for him, nor was a lawyer.
Thompson, an aspiring model who worked at a flower shop and restaurant, moved to Dallas about six months before her death in February 1984, the Dallas Morning News reported. She previously lived in Houston and Los Angeles.
Thompson was last seen two days before she was found dead behind a warehouse, strangled by her own leggings. She had taken a bus to a medical clinic which turned out to be closed, the newspaper reported.
Prosecutors said Dallas police reopened the case in 2009 and DNA testing was performed on autopsy samples. A male DNA profile was identified as never having been linked to a specific suspect and the case went cold again.
After police reopened the case in 2018, they worked with a team from the district attorney’s office and the FBI. Prosecutors said Morgan was identified as a suspect through technology that uses genealogy websites to identify potential relatives of a suspect based on DNA collected from a crime scene. DNA tests confirmed this week that he matched the profile taken from the 1984 autopsy.
