Officials in Utah have officially closed a 51-year-old cold case after utilizing new DNA technology to confirm that a murdered teenager was 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 a 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. Bundy confessed to Laura's killing before he was executed in Florida in 1989 but did not provide details about his involvement. The Sheriff's Department kept the case open until they could prove, without doubt, he was her killer, as stated by sheriff Mike Smith during a news conference. The investigation into Laura's disappearance and subsequent murder remains a poignant reminder of Bundy's terrifying legacy as one of America's most infamous serial killers, who began his spree attacking victims across the Pacific Northwest before moving to other states like Colorado and Florida. Laura is remembered as an outgoing free spirit who enjoyed outdoor activities and deeply cared for her siblings.
