[INTRO ♪] Back in the ‘70s and ‘80s, a man known as the ‘Golden State killer’ terrorized California, committing a string of more than 100 burglaries, 45 rapes, and a dozen murders. Definitely a bad dude. Even though the police had DNA evidence from crime scenes, it never matched any DNA records on file, so the case went cold ... Until last week. By this point, you’ve probably heard about this man’s capture. But you might not realize that the science used to crack the case is totally different from standard DNA forensics. So by understanding how DNA analysis is typically done for crime scenes, we can dive into why the Golden State killer case is so special. Usually, forensic scientists process DNA with a method called short tandem repeat, or STR, analysis. The basic idea ...
