Two suspected serial killers in California were registered sex offenders and were probably wearing their court-ordered GPS devices during the slayings, police say. Franc Cano, 27, and Steven Dean Gordon, 45, are suspected of raping and murdering at least four women in Santa Ana and Anaheim, and police say they are "confident" there was a fifth murder and possibly many more, reports the Los Angeles Times.
The men, who had known each other since at least 2012, were on parole and wore GPS trackers around the clock after serving time for sexually assaulting a child under 14. Investigators say data from the trackers helped linked the pair to the murders, the AP reports. Police departments around the country are checking missing-person cases for similarities to the California slayings. "We believe we have two serial killers in custody and we have stopped them in their tracks," a police spokesman says.
