Skeletal remains found in the Boundary Waters Canoe Area Wilderness last month are human, a medical examiner has confirmed, but identification of the deceased is still pending.

It’s believed the remains could belong to 29-year-old Jordan Grider, of Moriarty, N.M., who went missing in the area last fall.

According to the St. Louis County Sheriff's Office, deputies found Grider's vehicle at the Sioux Hustler trailhead on Oct. 22. Grider had notified family members and conservation officers that he had decided to spend the winter camped in the forest.

Authorities searched for Grider’s campsite, but did not locate it until April 5, roughly 1.5 miles from trailhead. According to a news release, a large amount of blood was found inside a tent at the site, but further search efforts were hampered by deep snow.

Authorities returned to the scene on April 25, finding apparent human remains scattered across a large area near the campsite. The sheriff’s office said it was not suspecting foul play.

The Midwest Medical Examiner’s Office, which examined the remains, confirmed this week that the bones were human.

“Initial report from the forensic anthropologist indicate they are human,” spokesman Erik Thorson said in an email. “Further examination and positive identification are pending.”
