A DNA breakthrough has solved the 52-year-old murder of a Utah police chief's teenage daughter, and the cold-case detective who helped crack it says notorious serial killer Ted Bundy could have other victims investigators do not even know about.Melissa Ann Smith, 17, the daughter of then-Midvale Police Chief Louis Smith, was found dead in 1974.For decades, investigators suspected Bundy but lacked the evidence needed to definitively tie him to her murder.That changed in July, when DNA evidence in the killing of another 17-year-old Utah girl, Laura Ann Aime, was matched to Bundy, allowing investigators to compare evidence preserved from Smith's case for more than half a century.POTENTIAL MICHIGAN SERIAL KILLER MAY HAVE LEFT BEHIND VALUABLE EVIDENCE, FORMER FBI PROFILER SAYS"There may be more victims out there that we're not even aware of, and I think there's always been that speculation," Salt Lake County Sheriff's Office Detective Ben Pender told Fox News Digital in an exclusive interview Wednesday.Ted Bundy previously confessed to a total of 28 murders, but investigators believe he could be responsible for hundreds of killings.
