When no new leads emerge in a murder or missing persons investigation, police must shift their resources to cases that offer new information. Currently, the FBI Uniform Crime Report keeps an estimated 250,000 cold cases on file, on which it co-operates with local law enforcement. Recent developments in AI, however, have shed light on some of these old and cold cases. For example, in 2018, DNA evidence submitted through a popular genealogy database enabled charges to be laid in more than a dozen cases involving the Golden State Killer who had been living " under the radar" for decades. According to a recent article in Forensic Science International, in 2018, direct-to-consumer (DTC) genetic genealogy databases were used to solve over fifty cold cases of either murder or missing persons.
