The news was announced at an Oct. 31 FBI press conference, and included Provincetown Chief of Police James Golden, Cape and Islands District Attorney Michael O'Keefe, First Assistant U.S. Attorney Josh Levy, as well as state and federal law enforcement authorities.Investigative genealogy was used to help identify Ruth Marie TerryHer identity was discovered using investigative genealogy, said Joseph Bonavolonta, a special agent with the Boston bureau, at the conference, a unique method that can generate new leads for unsolved homicides, as well as help identify unknown victims."This is, without a doubt, a major break in the investigation that will hopefully bring us all closer to identifying the killer," Bonavolonta said.On July 26, 1974, 12-year-old Leslie Metcalfe and her parents were hiking back to the Province Lands Visitors Center in Provincetown after a day at the C-scape dune shack when they came upon a gruesome discovery: the handless, nearly headless body of a woman.“What we need to do now is to learn everything about Ruth Terry’s life; what she did, where she went, who she associated with, all in hopes that those details and that timeline will lead us to her killer.”This has been a cold case since O'Keefe joined the Cape and Islands District Attorney's office."
