JACKSON (WNE) — The crash Saturday night that snarled traffic for hours on Highway 22 took the life of Jackson Hole High School student Wiley Jay Olsen, 17, of Alta.

Olsen was driving west on 22 at about 9:15 p.m. when his Subaru wagon left the roadway on the right side, Wyoming Highway Patrol Lt. Matt Brackin said.

“We’re not sure why, but Olsen swerved to his right, then overcorrected by swerving left,” Brackin said. The overcorrection caused Olsen’s Subaru to spin across the center line into a Ford Expedition driven by Jose Barrera of Jackson.

Barrera “didn’t have any time to react,” Brackin said, and his Ford struck the Subaru’s passenger side.

Olsen died at the scene just east of the entrance to Skyline subdivision. Barrera and his wife, a passenger in the Ford, were transported by ambulance to St. John’s Health, Brackin said.

The highway was shut down until around 11 p.m. so troopers could could investigate the crash scene, Brackin said, then officers were able to start letting cars through a single lane.
