Ted Bundy’s killing spree lasted at least four years. It left dozens of victims behind. At least 30 women and girls died. Several others escaped or survived despite suffering serious injuries.

The serial killer died nearly 40 years ago. However, investigators continue to identify his confirmed victims. Advances in DNA testing have helped reopen several cold cases.

A Utah sheriff confirmed Wednesday that Bundy killed a Utah teenager in 1974. The case had remained unsolved for decades. Authorities also expect another cold case to reach “close to closure” soon.

Utah County sheriff’s Sgt. Mike Reynolds said investigators now have Bundy’s complete DNA profile. The profile could help authorities connect him to additional unsolved cases.

Bundy remains one of the most prolific serial killers in U.S. history. However, other serial killers likely had higher victim counts.

Gary Ridgway admitted to killing 49 people. Investigators linked him to the Green River killings. Samuel Little claimed responsibility for more than 60 murders. Donald Harvey pleaded guilty to killing 37 people.

DNA technology continues to help investigators examine old evidence. These advances could reveal more victims linked to Bundy and other serial offenders.

New DNA testing confirms serial killer Ted Bundy killed a Utah teen in 1974

SALT LAKE CITY (AP) — The late Ted Bundy, one of the most famous and prolific serial killers in U.S. history, has claimed another victim.

New DNA testing confirmed Bundy was responsible for the 1974 killing of a 17-year-old Utah girl who disappeared after leaving a party alone on Halloween night, the local sheriff’s office said Wednesday.

Laura Ann Aime was found dead on the side of a highway in American Fork Canyon about a month after her abduction. She was bound, beaten and without clothing.

Investigators long suspected that Bundy killed her — police said he confessed without providing any details before his execution in Florida in 1989 — but the case remained open until they could be certain.

“It’s really quite amazing that people are even still interested in Laura’s case,” her sister, Michelle Impala, said at a news conference Wednesday. “Know I speak for my family when I thank you, and thank you media, too, for even caring.

Law enforcement officials have reopened a historic murder case after new DNA testing revealed crucial evidence. The findings connect the crime to a serial offender, highlighting the importance of preserving forensic data for future breakthroughs. Authorities are now reviewing similar unsolved cases.
