DNA Confirms Ted Bundy Killed Utah Teen Laura Ann Aime in 1974, Closing a 51-Year Case

A Halloween Night in 1974

On Halloween night in 1974, 17-year-old Laura Ann Aime left a party in Utah alone to walk to a nearby convenience store. She never returned. About a month later, hikers discovered her body on the side of a highway in American Fork Canyon. She had been raped, strangled, and murdered.

For more than 50 years, investigators pointed to Ted Bundy as the most likely suspect in her death. Bundy was attending law school at the University of Utah at the time of Aime’s killing and had been definitively linked to a string of murders in the region. But without forensic confirmation, her case remained officially open – a name in an investigation, not a legal conclusion.

The DNA That Closed the File

In April 2026, Utah authorities announced that advanced DNA analysis had confirmed what investigators had long suspected: the biological material recovered from Laura Ann Aime’s body in 1974 belonged to Ted Bundy. The Utah state crime laboratory acquired new technology in 2023 capable of extracting DNA from evidence that is small, heavily degraded from age, or contains genetic material from multiple individuals. That technology was applied to the 51-year-old evidence in Aime’s case and produced a definitive match.

Bundy was executed in Florida in 1989. He could not be charged or tried for Aime’s murder. But the DNA confirmation provides the formal legal and forensic closure that the case had never achieved – and gives Laura Ann Aime’s family a concrete, documented answer to a question they have carried for five decades.

Who Laura Ann Aime Was

Laura Ann Aime’s younger sister, Michelle Impala, has spoken publicly about who her sister was before that Halloween night. She described Aime as fun, outgoing, and deeply passionate about animals – a portrait of a 17-year-old with a specific personality and specific affections, not simply a name in a case file.

Aime is believed to be Bundy’s third victim in Utah, part of a murder spree that investigators now have more fully documented through decades of forensic work. In the years since Bundy’s execution, advances in DNA technology have continued to close cases that courts could not – returning names to the people behind unsolved deaths and returning, however incompletely, something to their families.

The Technology Behind the Answer

Forensic DNA work on 50-year-old evidence presents challenges that modern extraction methods are only beginning to overcome. The degradation of biological material over decades, combined with contamination from multiple DNA sources, historically made older evidence unreliable for profile matching. The technique used in the Aime case specifically addresses those limitations, allowing analysts to work with smaller, older, and more complex samples.

The result is a growing number of cold cases across the country being revisited with new tools applied to old evidence. Aime’s case is one of the most historically significant of these closures, given the prominence of Bundy’s name in American criminal history and the long shadow his cases have cast over the families of his victims.

Closure That Comes Fifty Years Late

The DNA confirmation does not undo what happened in American Fork Canyon in 1974. It does not change the decades that Michelle Impala and her family spent without a formal answer. What it does is add Laura Ann Aime’s name to the list of Bundy victims whose cases are now formally closed – confirmed, documented, and no longer categorized as unsolved.

For a girl who left a party alone on Halloween night and never came home, that confirmation arrives 51 years late. For her sister, who remembered her fondly and publicly when the news broke this spring, it is the only form of institutional acknowledgment that Laura Ann Aime’s death has ever received. It is, by every measure, long overdue.
