Officials in Utah have formally closed a 51-year-old cold case after using new DNA technology to identify a murdered teenager as a victim of serial killer Ted Bundy. Laura Ann Aime, 17, disappeared after leaving a party on Halloween in 1974. Her body was discovered about one month later by hikers in the American Fork Canyon. On Wednesday, the Utah County Sheriff's Office announced that new testing 'confirmed irrefutably that DNA evidence recovered from Laura's body verified the existence of DNA belonging to Bundy'. Between February 1974 and February 1978, Bundy murdered at least 30 women and is linked to many more killings across the country. Prior to his execution in Florida in 1989, Bundy confessed to Laura's killing but did not provide details, leading authorities to keep the case open until investigators could conclusively link him to her murder. 'This case is now officially closed,' declared Utah County Sheriff Mike Smith during a news conference. If Bundy were still alive, prosecutors indicated they would pursue the death penalty against him. Known for his charm and deceptive tactics, Bundy preyed on women in public before leading them to secluded areas to commit his crimes. The sheriff's statement described Laura as an 'outgoing free spirit' who enjoyed outdoor activities and cared deeply for her siblings.
