Leslie Perlov, a 21-year-old Stanford alumna who worked as a law librarian in Palo Alto and hoped to attend law school, was murdered on February 13, 1973. Her body was found on February 16 in the hills overlooking the Stanford campus. A floral scarf was tied tightly around her neck and used as a ligature; investigators reported signs that an attempted sexual assault had occurred.

Decades later investigators reexamined DNA recovered from under her fingernails and used genetic genealogy to identify a suspect, John Arthur Getreu, who had lived and worked near Stanford in the 1970s. A discarded trash sample of his DNA matched material on Leslie’s body, and he was arrested and charged. Getreu had prior convictions for violent crimes dating back to the 1960s and 1970s.

If anyone knew Leslie, her routines around Stanford, or saw anything in the campus hills in mid-February 1973, please come forward with information.
