A 51-year-old mystery is finally closed as the revolution in advanced forensics continues to reshape criminal justice.
On Wednesday, the Utah County Sheriff’s Office announced that new DNA testing definitively links serial killer Ted Bundy to the 1974 murder of 17-year-old Laura Ann Aime.
Aime vanished on Halloween night in 1974. She left a party alone in Utah County. A month later, hikers discovered her bound and beaten body in American Fork Canyon.
Bundy verbally confessed to killing her shortly before his execution in Florida in 1989. But words are not physical evidence. The case sat officially open for 51 years. Detectives simply lacked the genetic material to tie him to the crime scene.
That changed this week.
The breakthrough was confirmed according to a detailed report released Wednesday. It marks a major milestone for modern law enforcement agencies actively re-examining historical crimes.

What the Utah Crime Lab’s 2023 DNA Upgrade Means for Unsolved Murders
This resolution was catalyzed by a specific technological shift. The Utah state crime lab acquired new forensic extraction equipment in 2023.
This technology extracts genetic profiles from minute, severely degraded, or mixed DNA samples. Investigators matched carefully preserved physical evidence from the Aime crime scene to Bundy using a national law enforcement database. This created a confirmed DNA profile.
This profile is now a critical tool. Authorities are making this new forensic baseline available to other agencies nationwide. Officials hope the data will finally bring closure to families of other victims and solve the remaining cold cases linked to Bundy. The killer is suspected of murdering at least 30 women and girls across multiple states.
