More than 50 years after 17-year-old Laura Ann Aime vanished from a Halloween party in Utah County, authorities said Wednesday that new DNA testing had definitively linked her killing to serial murderer Ted Bundy, formally closing a 1974 cold case.cnn +1

Aime disappeared on October 31, 1974, after leaving a party to go to a convenience store. Her body was found nearly a month later, bound, beaten and unclothed down an embankment off American Fork Canyon Road, in the mountains south of Salt Lake City.cnn +1 Bundy, then a law student at the University of Utah, was long suspected and had confessed before his 1989 execution, but investigators held off declaring the case solved without physical evidence tying him to the scene.newsnationnow

How New Forensics Finally Closed a 51-Year-Old Case

Utah officials said the breakthrough came after the state crime lab acquired new DNA technology in 2023 capable of extracting genetic material from tiny, degraded or mixed samples.cnn +1 Detectives revisiting the file about a year ago resubmitted semen collected from Aime’s body in 1974; analysts were able to build a single male DNA profile from the decades-old swab.cnn +1

That profile was uploaded to the national CODIS database, where it matched an existing profile for Bundy maintained by Florida authorities, which notified Utah investigators in March 2026.nbcnews +1 “We can now say without a doubt that Theodore ‘Ted’ Bundy did, in fact, murder Laura Ann Aime in the fall of 1974,” Utah County Sheriff Mike Smith said as he declared the case officially closed.newsnationnow

What the Bundy Match Means for Other Cold Cases

Investigators said the confirmed profile will now be made available to other agencies as they review unsolved homicides from the mid-1970s that have long been suspected, but never conclusively proven, to be linked to Bundy.cnn +1 The Utah County sheriff suggested another Bundy-related development could follow as forensic teams apply the same technology to preserved evidence in additional cases.cnn

For Aime’s family, the announcement brought a measure of relief rather than a courtroom resolution. “Know I speak for my family when I thank you, and thank you media, too, for even caring,” her sister Michelle Impala said, adding that she had not realized the case was still technically open.cnn +1 Officials emphasized that while they “can’t really say closure,” the confirmation and public acknowledgment were intended to deliver “some type of healing” to relatives and a community that had lived with uncertainty for decades.nbcnews

The Bigger Picture

The Aime case underscored both the limits of Bundy’s own confessions and the growing power of modern forensics to settle questions left unresolved for generations. Authorities said that while the confirmation came too late for prosecution, it validated the decision to preserve physical evidence and revisit old files as DNA science advanced, offering a model for how other long-dormant cases tied to notorious offenders might finally be resolved.cnn +1
