Cook County State's Attorney Anita Alvarez announces first-degree murder charges against Michael Gargiulo during a news conference in Chicago, Thursday, July 7, 2011, in the cold case murder of 18-year-old Tricia Pacaccio, of Glenview, Ill., who was killed in 1993. Gargiulo already faces murder charges in California. Pacaccio was stabbed in the chest as she was about to unlock the door to her family's home. Her father found her body hours later. Authorities say Gargiulo knew Pacaccio and was questioned about her death but never charged. (AP Photo/Charles Rex Arbogast) less
