Remains believed to be of an Air Force Academy preparatory school student were found Friday in Rocky Mountain National Park, officials said.

Micah Tice, 20, was reported missing in November, and his vehicle was found not long afterward at the Longs Peak Trailhead. The search for Tice at the time, however, was unsuccessful.

On Thursday, searchers hired by the Tice family contacted the park staff and reported finding items believed to have been Tice’s below treeline in the Boulder Brook drainage, according to a news release from the park.

The Boulder Brook drainage had been heavily focused on during initial searches, but the area then was covered in deep snow, park officials said in the news release.

After Thursday’s discovery, Rocky Mountain National Park Search and Rescue team members searched the drainage Friday morning and discovered what are believed to be Tice’s remains, the release said. The Larimer County coroner’s office will rule on a positive identification after an autopsy is complete.
