Michael Gargiulo, the so-called Hollywood Ripper, was a predator who operated in plain sight, drifting through Los Angeles with the easy confidence of a man no one suspected. His violence began in 1993, when he murdered 18-year-old Tricia Pacaccio in Illinois at just sixteen, then followed him west years later. In Hollywood, he befriended and fixated on 22-year-old fashion student Ashley Ellerin, stabbing her to death in 2001 the night she had a date planned with Ashton Kutcher. Four years after that, he murdered Santa Monica resident Maria Bruno with the same frenzied knife attack style.
