New DNA evidence has linked serial killer Ted Bundy to the 1974 murder of a Utah teenager, a county sheriff announced this week, potentially resolving a cold case that had gone unsolved for more than 50 years. The testing represents one of the first forensic connections between Bundy and a previously unattributed killing from that era.

Bundy, who was executed in 1989, confessed to 30 murders across multiple states before his death, though investigators have long suspected the true number of his victims was higher. The Utah case had remained open due to insufficient evidence at the time of the original investigation, and the victim's death had not been conclusively attributed to any perpetrator.

Advances in forensic DNA technology have allowed investigators to revisit decades-old evidence and draw conclusions that were not possible with earlier methods. Cold case units across the country have increasingly relied on such techniques to resolve longstanding investigations, sometimes producing results that either confirm or challenge earlier assumptions about unsolved crimes.

The sheriff's announcement brought renewed attention to the scope of Bundy's crimes and to the families of victims who never received definitive answers. Investigators have not disclosed the specific methods or evidence used in the DNA analysis, citing the ongoing nature of the case review.
