WASHINGTON STATE — The Utah County sheriff's office expected another cold case would be close to closure soon using Ted Bundy's full DNA profile, Sgt. Mike Reynolds of the office said.

The development follows advancements in DNA testing that have led to additional confirmed victims of Bundy, who is one of the most prolific serial killers in United States history. At least 30 women and girls were killed by Bundy, and several other victims escaped or survived despite serious injuries.

Bundy was responsible for the unsolved death of a Utah teenager in 1974, Reynolds said. By October of that year, teen girls were vanishing in Utah.

DNA testing confirmed that Bundy killed 17-year-old Laura Ann Aime. Aime went missing in Utah on Halloween night in 1974, and her body was found a month later on the side of a highway. Authorities believe she had been kept alive for several days after her abduction.

Evidence from Aime's case was preserved and later allowed investigators to extract a DNA profile matching Bundy and close the case.

Bundy's violent spree spanned at least four years. His typical method involved breaking into young women's homes, bludgeoning and sexually assaulting them, and leaving them to die or dumping their bodies elsewhere.

Bundy was executed in 1989. Investigators have continued to revisit unsolved cases in which he is suspected, and the availability of his full DNA profile has enabled the Utah County sheriff's office to pursue additional closures, Reynolds said.
