SAN FRANCISCO – Northern California authorities say they have cracked a 45-year-old murder case using the same publicly available DNA database investigators accessed to arrest alleged serial killer Joseph DeAngelo.

The Santa Clara County sheriff’s department said Wednesday that officers arrested 74-year-old John Arthur Getreu on suspicion of killing 21-year-old Leslie Perlov in 1973. Perlov’s body was under an oak tree near Stanford University and her panty hose were stuffed in her mouth. She had been strangled and the case went unsolved for decades.
