Veteran cold-case investigator Paul Holes spent decades working California crime scenes. He played a critical role in identifying former police officer Joseph James DeAngelo Jr. as the so-called Golden State Killer, a notorious serial predator who was responsible for at least 13 murders and 50 rapes in the 1970s and '80s.
In fact, the day before Holes retired, he drove to the home of DeAngelo, then a prime suspect, and debated knocking on the door to ask him for a DNA sample.
