Los Angeles Police Chief Charlie Beck says detectives investigating the suspected "Grim Sleeper" serial killer have opened four new missing person cases.
Beck told KTLA-TV on Thursday that the cases were opened after investigators were flooded with information following the release of about 180 photos that were found in the home of Lonnie Franklin Jr., who was arrested in July and has pleaded not guilty to the murders of 10 women.
Beck says investigators have so far been able to identify more than 50 of the women.
He says it was a tough decision to release the photos, many of which include women in sexual acts, but he was confident additional victims would be discovered.
