Steve Kroft reports on how a new tool that uses a mixture of DNA analysis and family genealogy has been helping law enforcement crack cold cases.
Barbara Rae-Venter never anticipated that her genealogy hobby would lead to the capture of one of California's most notorious criminals, the Golden State Killer. Her pioneering use of genetic genealogy has since helped solve numerous cold cases.
