SAN FRANCISCO (AP) – Rodney Halbower, 66, is suspected of being a serial killer who raped and murdered five young women in Northern California and one in Reno, Nevada, during a four-month span in early 1976.

Cold case detectives, using DNA technology, said they matched genetic material kept from three of the murder scenes with Halbower’s DNA. Halbower is charged in California with two of the murders. He has not entered a plea. Instead, a judge has ordered a psychiatric review of Halbower to determine if he’s sane enough to stand trial.
