Between 2001 - 2008, a series of murders & attacks on young women horrified Los Angeles, California. The crimes were meticulously planned but ultimately he messes with the wrong girl and after a huge struggle, leaves DNA behind. That DNA links him to a 1993 cold case that should've landed him in jail before he could kill again. When he finally goes to trial, the prosecutor has a very surprising star witness. Stick around to the end because there are some new (and damning) allegations. This is the story of Tricia Paccacio, Ashley Ellerin, Maria Bruno, and Michelle Murphy.
