Joseph James DeAngelo, who authorities suspect is the so-called Golden State Killer responsible for at least a dozen murders and 50 rapes in the 1970s and 80s, was arrested more than three decades after the last killing with the help of information from an online genealogical site. Investigators haven't disclosed many key elements about how and why they took this very unusual step to find a suspect. Here's a look at the case and some of the questions surrounding it: HOW DID AUTHORITIES IDENTIFY HIM? The Sacramento County district attorney's office said Thursday DNA from one of the crime scenes was checked against genetic profiles from genealogical websites that collect DNA samples to help people learn about their family backgrounds.
