You might not remember the name of serial killer Michael Gargiulo – also known as the ‘Hollywood Ripper,’ for his California knifings, ‘The Boy Next Door Killer,’ because he lived so close to his victims, and the ‘Chiller Killer,’ for using his job as an air conditioning repair man to gain his victims’ trust – but I bet you remember that case where actor Ashton Kutcher’s date was murdered or recall Ashton testifying at the killer’s trial a few years ago.
