A 60-year-old Dallas man was arrested on a capital murder charge and accused in connection to the cold-case rape and murder of a woman.
This week, Edward Morgan was charged with killing Mary Jane Thompson, 21, who was also sexually assaulted, the Dallas County district attorney’s office said in a statement.
Thompson, an aspiring model who worked at a florist’s shop and a restaurant, moved to Dallas about six months before her 1984 death. She moved after previously living in Houston and Los Angeles, according to The Dallas Morning News.
Thompson was last seen two days before she was found dead behind a warehouse, strangled by her own leg warmers after she took a bus to the Trinity Medical Clinic, which was closed.
Dallas Police reopened the case with the help of the Dallas County District Attorney's Sexual Assault Kit Initiative based on new types of forensic testing techniques, prosecutors noted.
Investigators used a process called genetic genealogy to help find the suspect, prosecutors said. That process, which was the same used to identify the "Golden State Killer." Investigators use a DNA sample to create a family tree to create a profile and identify a suspect or a victim.
Recently, DNA testing confirmed that Morgan's DNA matched a swab taken from Thompson during her autopsy.
