Cracking the Code

Open Ninth Episode 133

The Golden State Killer’s unsolved crimes haunted Californians for decades. With little evidence and no new leads, the case grew cold. Then, Dr. Barbara Rae-Venter got involved. Using investigative genetic genealogy to identify distant relatives of the killer, Dr. Rae-Venter narrowed down a long list of potential subjects to just one: Joseph James DeAngelo. Listen in as she talks with Chief Judge Lisa Munyon about her work on the case and how investigative genetic genealogy is evolving.
