For nearly a year, the man known only by his scattered bones on a remote Wyoming mountainside remained a mystery.
Investigators found pieces of his skeleton spread across rugged country near the Sweetwater Gap Guard Station, along with a tent and personal belongings.
An identification card hinted at who he might be, but proving it would require an investigation stretching from Sublette County to Scotland, involving Interpol, foreign police agencies and DNA collected half a world away.
On Thursday, the Sublette County Sheriff's Office announced the mystery has finally been solved.
The remains belong to John Gillies, a Scottish man who would have been 69 years old this year.
"This case is a testament to the dedication of everyone involved and the strength of partnerships that extend well beyond our county and even our nation's borders," Sheriff K.C. Lehr said in a statement.
"What began as the discovery of unidentified remains in a remote area of Wyoming ultimately brought together local, state, federal and international partners with one shared goal — to give a family answers,” he said.
'Very Remote'
The investigation began Sept. 6, 2025, when Wyoming Game and Fish personnel discovered scattered human skeletal remains in a remote section of the Wind River Mountains near the Sweetwater Gap Guard Station.
Authorities later described the location as "very remote," in an area that sees little traffic outside of occasional search-and-rescue missions.
Deputies found disarticulated skeletal remains, a tent, and personal belongings. At the time, authorities said foul play did not appear to be a factor.
Four days later, a 14-member search team made up of deputies, detectives, Sublette County Search and Rescue volunteers and U.S. Forest Service personnel combed roughly 20 miles of rugged terrain, recovering additional skeletal remains.
By late December, a forensic anthropologist estimated investigators had recovered about 85% of the skeleton and concluded the remains had likely been in the wilderness for about six years.
'More Than Bones'
Among the items recovered at the scene were personal effects that eventually led investigators to believe the man could be Gillies.
With no immediate next of kin in the United States, detectives contacted Gillies' ex-wife on Sept. 16, 2025.
Although she had not yet received confirmation that the remains belonged to her former husband, she provided photographs, medical history and details about his life.
One message stayed with investigators throughout the case.
"I wanted you to know he was more than bones" she had said.
The sheriff's office called her compassion and willingness to help "a powerful reminder that every unidentified person is someone's loved one."
Investigation Crosses An Ocean
The investigation soon expanded across the Atlantic.
Detectives contacted Saint Mary's Church in Kirkintilloch, Scotland, which helped locate Gillies' surviving relatives and assisted with an international death notification.
Through Interpol, Police Scotland and the Scottish Crime and Drug Enforcement International Bureau, investigators obtained DNA reference samples from Gillies’ family, the Sublette County Sheriff’s Office reports.
Those samples arrived in Wyoming on Feb. 10. The following day, investigators personally transported the family DNA and the recovered skeletal remains to the Wyoming State Crime Laboratory in Cheyenne for comparison.
On Tuesday, the lab confirmed the remains were biologically related to Gillies' surviving family members, bringing the nearly yearlong investigation to a close, along with six years of limbo overall for the family.
Investigators immediately notified his family in Scotland.
At their request, the Sublette County Sheriff's Office and the Sublette County Coroner's Office are now working with Interpol to return Gillies' remains home for burial.
Questions Remain
The sheriff's office did not say how Gillies came to be in the isolated Wyoming wilderness or whether he had been reported missing before his remains were discovered.
Authorities also did not announce a cause or manner of death.
Instead, investigators focused Wednesday on the collaboration that ultimately restored a name to a man who had spent years missing and unidentified.
"We are grateful to everyone who played a role in helping bring John home," Lehr said.
The sheriff's office specifically thanked the Wyoming Game and Fish Department, Sublette County Search and Rescue, the U.S. Forest Service, the Wyoming State Crime Laboratory, Interpol, Police Scotland, the Scottish Crime and Drug Enforcement International Bureau, Saint Mary's Church in Kirkintilloch and, most importantly, Gillies' family "for their patience, trust and assistance throughout this investigation.”
