DNA, forensic genealogy close 65-year-old double homicide
GREAT FALLS, Mont. (AP) — DNA evidence preserved after a 1956 double homicide and the use of forensic genealogy has helped a Montana sheriff’s office close the books on the 65-year-old cold case, officials said.
Investigators with the Cascade County Sheriff’s Office concluded Kenneth Gould — who died in Oregon County, Missouri, in 2007 — more than likely killed Patricia Kalitzke, 16, and Duane Bogle, 18, the Great Falls Tribune reports. Both were shot in the head.

Officers investigated for years, but they were unable to make an arrest.
The case went cold for decades until 2001, when then-Detective Phil Matteson sent the slide of a vaginal swab gathered from Kalitzke’s body to the Montana State Crime Lab for analysis. The lab found a sperm cell that did not belong to Bogle, officers said.
In the following years, law enforcement compared the DNA sample to about 35 other men, including gangster James Joseph “Whitey” Bulger Jr. They were all ruled out as suspects.
When Matteson retired, he said he didn’t believe the case would be solved. “A lot of different people had a turn at this, and we just weren’t able to take it to conclusion,” he said.
In 2018, however, forensic genealogy, which was...
