They then investigate multiple branches of the family’s tree to determine who could be a viable suspect in the unsolved case. The technique, in which a genealogist plugs a suspect or victim’s DNA profile into a public genealogy database, allows them to reverse engineer a family tree for the owner of the profile.
The arrest of Joseph James DeAngelo, California’s notorious Golden State Killer, in April 2018 introduced the world to the advent of genetic genealogy. Kadner, who was assigned the case in 2012, said the big break in the case came six years later, when another case more than 1,000 miles away was solved.

Over the next several decades, authorities would investigate, and clear, nearly three dozen suspects, including notorious gangster James “Whitey” Bulger, who had been charged with rape in Great Falls five years before the murders.Īccording to the Tribune, now-retired Detective Phil Matteson sent a vaginal swab from Kalitzke’s autopsy to the Montana State Crime Lab in 2001, at which time lab technicians found a vital clue - that single sperm cell, which did not belong to Bogle.ĭespite that find, the case remained unsolved when Matteson retired. Kadner theorized that the killer fatally shot Bogle before kidnapping Kalitzke to rape her, according to the Electric. She, too, had been shot and her body bore injuries inflicted during a sexual assault.

The Times reported that the teens’ families assumed they had eloped - until three boys hiking near the Sun River the next day found Bogle’s body. From there, they apparently parked at a lover’s lane west of Great Falls, near Wadsworth Park.
