She was 37 years old at the time of her death, according to Agent Bonavolonta.

The FBI said the cause of death was determined to be a blow to the head that happened several weeks prior to her body being discovered.

According to the FBI, "this is a unique method that can generate new leads for unsolved homicides, as well as help identify unknown victims." In the 48 years since her body was discovered, "many investigative and scientific techniques have either improved or been created through new advances in technology," Agent Bonavolonta explained. "One of these methods is Investigative Genealogy and combines the use of DNA analysis with traditional genealogy research, and historical records, to generate investigative leads for unsolved violent crimes," the FBI agent continued. He added, "Just last week, the FBI received positive confirmation of Ruth's identity through the genealogical examination of this infamous cold case." Ruth Marie Terry.
