Three badly decomposed bodies have been found in and around a tent in the rugged Colorado wilderness.

A hiker came across a tent with a body outside of it in the Rocky Mountains of central Colorado on Sunday, Gunnison County Undersheriff Josh Ashe told USA TODAY on Wednesday.

The hiker reported the find to authorities, and the sheriff’s office found two other bodies inside the zipped-up tent the next day, Ashe said, adding that they appeared to have been dead “for a substantial period of time.”

There were no signs that a crime or a murder-suicide had occurred. An attack by an animal is unlikely because of how the two were zipped up in the tent. There is no known risk to others in the area related to the deaths, Ashe said.

Investigators hope that autopsies will help them determine what happened.

It could be that the trio got lost in the area in the fall and succumbed to the elements or starvation as winter arrived. The area experiences subfreezing temperatures and extremely deep snow.

Their tent was located in a secluded, heavily wooded spot about 350 yards from a campground that sits alongside a winding, dirt road. The nearest town to the Gold Creek Campground is the sparsely populated Ohio City, about 6.5 miles away.

“It looked to me that they set up camp there and wanted to be there and unfortunately, tragic events occurred,” Ashe said. “How they ended up there, why they chose that location, that’s still something we’re trying to decipher.”
