The Hollywood Ripper: He Was Watching Them (S07E06)

On February 21, 2001, a young woman is brutally killed in her Hollywood home just hours before her date with actor Ashton Kutcher. As investigators dig deeper, her friends recount encounters with an uninvited air conditioning repairman known only as "Mike." As the case progresses, police uncover that his full name is Michael Thomas Gargiulo, and he might be connected to a murder from nearly eight years prior in Illinois. Although he remains a suspect and hasn't been apprehended, Gargiulo continues his violent spree until one courageous woman fights back and manages to escape.
