The NorCal Rapist, a man who allegedly sexually assaulted a number of women between 1991 to 2006, was arrested today with the help of genetic genealogy. Local news station CBS13 reports that 58-year-old Roy Charles Waller was arrested Friday when he showed up for work at UC Berkley. At a news conference, Sacramento County District Attorney Anne Marie Schubert said Waller was arrested after a DNA match was made through GEDmatch—the same company that help catch the suspected Golden State Killer. “The answer has always been in the DNA,” Schubert said. UC Berkeley said in a statement that there was “no indication” that Waller committed any crimes on campus but it is “still reviewing any open sexual assault cases.” Waller worked at the university as a safety specialist in the Environment, Health & Safety office since 1992. He is now facing three felony charges, with his first court date is scheduled for September 24.
