DNA cold case: Kenneth Gould is pictured in an undated photo.
Air Force airman, was stationed at Malmstrom Air Force Base when he met and fell in love with Kalitzke.
The couple, who were on a date the night of the murders, were last seen at a drive-in restaurant just after 9 p.m.
A Cascade County road worker stumbled upon Kalitzke’s body a day later, dumped off a gravel road north of Great Falls.
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.
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.
Kadner began working in 2019 with Bode Technology, which conducted further testing on the semen taken from Kalitzke’s body, according to KRTV in Great Falls.
A little over a month after the murders, Gould sold his family’s property and moved his family, which included a 2-month-old daughter, out of Great Falls.
Investigators who tied Gould to the crime were unable to uncover any connection between him and the victims, the Tribune reported.
