3 people remain hospitalized after tourist bus flips on its side in Grand Teton National Park

Three people injured when a tourist bus flipped on its side in Grand Teton National Park remain in the hospital.

Two people are being treated at the Eastern Idaho Medical Center in Idaho Falls, Idaho, where they were listed in fair condition Saturday. Another person remains at St. John's Medical Center in Jackson, Wyoming, in good condition.

The bus was carrying 26 Asian tourists and a driver when the accident occurred about 4:10 p.m. Thursday. The bus was traveling on U.S. 89 to Yellowstone National Park.

Authorities believe the 33-foot-long bus went off the pavement and the driver overcorrected, causing the accident.

The National Park Service says the bus belonged to Salt Lake City-based Roaming America Travel. Messages left with the company weren't immediately returned.

The accident remains under investigation.
