The NorCal Rapist

Roy Charles Waller (born January 8, 1960) is an American serial rapist. He was arrested in September 2018 as a suspect in the series of hoodlums and abductions committed between 1991 and 2006 in six Northern Californias (NorCal rapist). DNA evidence from the school's current mission was matched on the online DNA matching task, GEDmatch, with a relative of Waller, and he was verified through a genetics-based system.

Police created a genealogy tree and used known elements of the rapist, luring the suspects down to Waller. After confirming the GEDmatch, it took them about a week to identify and capture the scope. He was charged with total rape, which took place in five different counties, including Sonoma, Solano, Contra Costa, Yolo and Butte. At the time of his arrest, he was living in Benicia, married, and employed as a safety expert at the University of California Berkeley. He worked there for 26 years. He was convicted of 46 counts in November 2020. The same communications systems technique was used to identify and arrest the suspect known as the Golden State Killer.
