It was just three days right into 1956 once three guys from Montana, out for a hike ~ above a typical January day, make a gruesome discovery they were unlikely to ever forget.

During a walk close to the sun River, they discovered 18-year-old Lloyd Duane Bogle, dead indigenous a gunshot wound come the head. They discovered him ~ above the ground near his car, and someone had actually used his belt to tie his hand behind his back, follow to a report indigenous the an excellent Falls Tribune. The next day brought another disturbing discovery: A county road worker discovered 16-year-old Patricia Kalitzke"s body in an area north of an excellent Falls, the record reports. She had been shooting in the head, just as Bogle had actually been, yet she had likewise been sexually assaulted.

Their killings walk unsolved until this week as soon as investigators announced they had actually cracked what is thought to be the oldest situation solved through DNA and also forensic genealogy.

The victim were uncovered in a lover"s lane

Bogle, one airman hailing from Texas, and Kalitzke, a small at an excellent Falls High School, had fallen because that each other and also were also considering marriage, the Tribune reports. The location where they were believed to have actually been killed was a recognized "lover"s lane," according to a trimming from a neighborhood newspaper posted on a memorial page.

But your love story to be brutally cut short by the actions of a killer whose identity would no be revealed for an ext than 60 years. And also it was not for lack of trying: early in the case, investigators followed plenty of leads, yet none of castle panned out. The situation eventually walk cold.

For decades, the Cascade ar Sheriff"s Office ongoing to occupational on it, through multiple detectives attempting come make progression over the years. One such investigator was Detective Sgt. Jon Kadner, who was assigned the instance in 2012 — his very first cold case, the said during an interview v That was immediately met v the an overwhelming task the digitizing the expansive instance file, an venture that take it months.

He ongoing to work on the Kalitzke/Bogle case even while taking care of the newer instances that were landing on his desk all the time, however he had actually a feeling that more was essential to acquire to the bottom the what had happened to the couple all those decades ago.

"My very first impression was that the only way we"re gonna ever solve this is v the use of DNA," Kadner said.

Detectives turned to a brand-new forensic investigation

Fortunately, Kadner had actually something to work with. During Kalitzke"s autopsy in 1956, coroners had actually taken a quality swab, which had actually been maintained on a microscopic slide in the years since, according to the Great drops Tribune report. Phil Matteson, a now-retired detective with the sheriff"s office, sent out that sample to a local lab for experimentation in 2001, and also the team there determined sperm that did no belong come Bogle, she boyfriend, the paper reports.

Armed through this knowledge, Kadner in 2019 sought out the help of Bode Technology. After forensic family tree was offered to ultimately nab the gold State Killer the year prior, regulation enforcement public representative were becoming increasingly aware of the potential to use that modern technology to resolve cold cases — even decades-old instances like Kalitzke and also Bogle"s.

With the aid of partnering labs, forensic genealogists are able come use preserved samples to develop a DNA profile of the culprit and then usage that profile to find public databases for any type of potential matches. In many cases, those file can end up linking to remote relatives the the culprit — say, a 2nd or 3rd cousin. By looking public records (such as fatality certificates and newspaper clippings), forensic genealogists space then maybe to build a household tree the can point them right to the suspect, even if the suspect has never noted their DNA to any public database.

In this case, "Our genealogists, what they"re walk to perform is independently build a family tree indigenous this cousin"s profile," Andrew Singer, one executive with Bode Technology, said He dubbed it "a reverse family tree. ... We"re essentially going backwards. We"re beginning with a distant relative and also trying to work earlier toward our unknown sample."

It worked: DNA testing led investigators come a man named Kenneth Gould. Prior to moving come Missouri in 1967, Gould had lived through his wife and children in the an excellent Falls area about the time of the murders, follow to the Tribune.

"It felt good because for the an initial time in 65 year we lastly had a direction and also a ar to take the investigation," Kadner called "Because the was all theories as much as that point ... We finally had a match and we had a name. That adjusted the totality dynamic that the case."

Investigators" goal is a safer world

But there to be one huge problem: Gould had passed away in 2007 and his remains had actually been cremated, according to the Tribune. The only way to prove his guilt or his innocence to be to test the DNA of his continuing to be relatives.

Detectives had an uncomfortable task ahead that them: letting a dead man"s family members know that, in spite of the fact that he"d never ever previously been identified as a human being of interest, he was currently the an essential suspect in a double homicide and rape.

Authorities traveled to Missouri, wherein they spoke through Gould"s children and also told them about the Kalitzke/Bogle case and eventually determined their father together a suspect, Kadner said. They asked for the family"s aid in one of two people proving or disproving the Gould was the man responsible and also the household complied.

The test outcomes said Gould to be the guy. V the killer ultimately identified, Kadner was able to reach the end to the victims" surviving relatives and also deliver the closure that had taken an ext than 60 year to procure. It was a bittersweet revelation: castle were grateful for answers, however for countless of the older world in the family, it to be a battle to have actually those wounds reopened.

"They"re excited, however at the very same time, the has brought up a most memories," Kadner said.

Now, the sheriff"s office is considering creating a cold situation task force, as other regulation enforcement agencies have done. The expect is that they"ll be able to provide more families v the answers they worthy and, in numerous cases, have actually spent years wait for.

"If there"s new technology and we are able to perhaps solve something, we want to store working in ~ it, due to the fact that ultimately we"re do the efforts to perform it for the family," that said. "Give them some closure."

The Kalitzke/Bogle situation is one of the oldest criminal situations that has been solved using forensic genealogy, and also authorities are positive that they"ll have the ability to use this ever-advancing technology to solve cold cases dating ago even further — although brand-new state law restricting forensic genealogy could complicate matters.

Even without that complication, Singer defined to, the success rate depends greatly on how well the proof has been preserved over the years. Still, he hopes that it have the right to be supplied to help law enforcement enhance public safety and also " tomorrow"s victim."

"It"s really an excellent technology and it"s walk to deal with a many cold cases," Singer said.
