1956 double murder of Lloyd Bogle and Patricia Kalitzke closed due to DNA match; suspect died in 2007
Update

A double murder that took place near Great Falls, Montana on January 2, 1956 is believed to have been solved thanks to genetic genealogy.

The Cascade County Sheriff’s Office has closed out what they believe may be the oldest "cold case" in the country after more than 65 years.

Through the use of forensic genetic genealogy, they say Kenneth Gould is the most likely suspect in the rape and murder of 16-year-old Patricia "Patty" Kalitzke and the murder of her 18-year-old boyfriend Duane Bogle in Great Falls in early January 1956.

On the evening of Jan. 2, Kalitzke -- who was a junior at Great Falls High School, and Bogle, a Malmstrom airman -- ventured to a spot west of Great Falls near Wadsworth Park along the Sun River.

The next day, three kids found Bogle’s dead body, with a gunshot wound to the head, face down next to his vehicle.

The following day, a county road worker spotted what was identified as the body of Kalitzke about five miles away to the north on Vinyard Road near what is known as Hill 57. She had also been shot in the head.

The investigation revealed semen in her body, indicating she had been raped.

DNA testing had previously been used to rule out James "Whitey" Bulger and serial killer Edward Wayne Edwards. In 2019, detectives used a company called Bode Technology to conduct genetic genealogy on the DNA to try and identify the suspect. This led to Gould, who had died in 2007. However, DNA from his children resulted in a match.

At the time of the murders, Gould lived about a mile from Patty's home. He also worked corralling horses just a few blocks from her home. Interestingly, he has no known criminal history. However, a month after the murders, he sold the family property and moved out of the area.

It's amazing to see a 65 year old case being solved, especially with the help of genetic genealogy.
