After a three-day search, the 20-year-old Russian student who went missing in Wyoming's Grand Teton National Park was found dead.

On Friday afternoon, authorities discovered the body of Aleksandr "Sasha" Sagiev's below Cache Couloir, a steep traverse in Glacier Gulch. After his body was found at an elevation of around 9,400 feet, a helicopter long-line was used to remove it and transport it to Jackson, Wyoming, said the National Park Service on Friday, according to CBS News.

Sagiev, who was originally from Nizhny Novgorod, Russia, was first reported missing on Monday after he went on a hike.  He was last seen on Sunday, Aug. 17 at Dornan's Pizza & Pasta Restaurant, a shop near the park where he worked as a seasonal employee.

About 60 searchers had been looking for him, but officials ran into complications due to heavy rain and thick clouds near Taggart Lake Trailhead, where authorities believed Sagiev started his hike.

Officials began searching for the student in the Moose area. "However, on Thursday afternoon, they received information indicating Sagiev may have started a hike from Taggart Lake Trailhead on Monday morning," reports Local News 8.

According to a press release issued by the National Park Service, "Sagiev was wearing the metallic blue "Sochi" jacket described in missing person flyers distributed to the public, which helped in locating his body in the rocky terrain."

"Search teams found Sagiev's body at 1:25 p.m. in Glacier Gulch approximately 1/3 mile west of Delta Lake," reads the press release. "Sagiev was declared dead at the scene by the searchers in consultation with Dr. Will Smith, the park's medical director. The circumstances of Sagiev's death are still under investigation."

The cause of his death was not immediately revealed, but park officials said that the circumstances surrounding his death are currently being investigated.
