Cascade County Sheriff’s Office investigator Sgt. Jon Kadner told CNN in an interview that “It was such a big case. Two popular kids who were essentially gunned down in a Lover’s Lane situation,” said Kadner.

Investigators now know the killer was Kenneth Gould. In 1956 he was a Great Falls native. And grew up near one of the victims.

Patricia Kalitzke, 16, and her boyfriend Lloyd Duane Bogle, 18, were found near Bogle’s car. Kalitzke had been sexually assaulted. And both teens were fatally shot in the head.

In 2001, a DNA profile of a suspect was developed using forensic evidence preserved from Kalitzke’s 1956 autopsy, Kadner said. 

Later the evidence was compared to DNA available in private commercial databases like Ancestry.com.

“They built a family tree backward and then forward to develop (the link to) Kenneth Gould,” Kadner said.

By the time Gould became the prime suspect, “He died in 2007 and was cremated,” Sgt. Kadner said.

Investigators had no way to confirm his guilt directly with DNA.
