It was January 1956 when three boys, who were out on a New Year's hike in Sun River, Montana, found the body of 18-year-old Lloyd Duane Bogle with his hands tied behind his back laying on the ground near his car. He had been shot in the back of the head. The next day a county road worker found the body of Bogle's 16-year-old girlfriend Patricia Kalitzke. She had been shot in the head just like her boyfriend but had also been sexually assaulted. Their bodies had been found in what is known as "lover's lane". great falls history museum

Bogle was an airman from Texas, and Kalitzke was a junior at Great Falls High School, that had fallen hard for one another and were considering marriage after Kalitzke graduated high school. Early on in the investigation there were a lot of leads to go on, but none panned out, and eventually they ran dry. 

The Cascade County Sherriff's office never gave up. For decades they continued to investigate these murders, with several detective attempting to solve it. In 2012 a new investigator was assigned to the case, Detective Sgt. Jon Kadner. This was his first cold case, and even though he had other cases land on his deck, he didn't give up on this one. He was assigned the task of digitizing the case file, a task that took several months. After a while, Kadner realized that the only way they were going to be able to solve the case would be through DNA. 

The original investigator had saved a vaginal swab they took from Kalitzke, and after ruling out the DNA belonging to Bogle, they were then able to seek out the assistance of Bode Technology. With the help of other labs, forensic genealogists were able to create a genetic profile, using the swab they had taken 63 years earlier. Forensic scientists are able to create family trees by using death certificates and searching public records. By creating this family tree, they are able to find a suspect, even if that person never submitted DNA to the website. In this case, it was a distant cousin, and they were able to create a reverse family tree. By doing this, it led them to a man named Kenneth Gould. He had lived with his family in Great Falls during the time of the murders, and before moving to Missouri in 1967. 1956 double homicide

After six decades, the police finally had a direction. Unfortunately, Gould had died in 2007. That meant that the investigators had to use remaining family members to get determine if he was the man they were looking for. It wasn't easy on the investigators because they had to go to his children and essentially tell them that their dad was being investigated for double murder and rape from a case in 1956. They cooperated and after all this time, they had their killer. Kenneth Gould was the killer/rapist. The familied to Bogle and Kalitzke finally had justice. It was one of the oldest cold cases solved with genetic genealogy.
