Harvey Castro talks about how AI could be used in cold cases and the symbiotic relationship between AI and a detective. Riverside, California, investigators linked a man's DNA to a 1979 cold case murder of a teenage girl, years after the same man passed a lie detector test about the crime, according to authorities. The body of 17-year-old Esther Gonzalez was found dumped in packed snow off Highway 243 in Banning, California, in 1979, and after an investigation, detectives determined the teen had been raped and bludgeoned to death. Last week, the Riverside County District Attorney's Office said in a press release that the case had been solved using forensic genealogy, over 45 years later. On Nov. 20, the Riverside County Regional Cold Case Homicide Team identified Lewis Randolph "Randy" Williamson, who died in 2014, as the killer.
