Valley, Ala., man injured in Grand Teton rollover|

MOOSE, Wyo. (AP) — Four people were injured, one critically, when a pickup truck carrying seven people missed a curve on a dirt road and rolled over in Grand Teton National Park.

The truck was returning from a backwoods party and park officials said possible alcohol use was being investigated.

The crash happened around 1:40 a.m. Saturday. Park officials said Matthew Stiles, 21, of Valley, Ala., was driving six other people in a 2007 Ford F-150 on Wilderness Road.

Stiles was listed in critical condition Saturday at Eastern Idaho Regional Medical Center in Idaho Falls, park spokeswoman Jackie Skaggs said. His condition was not immediately available through the hospital Sunday.

The passengers’ injuries included broken bones, cuts and bruises and weren’t life-threatening, Skaggs said.

Four of the passengers were riding in the pickup’s cab. One was taken to St. John’s Medical Center in Jackson. The other two passengers were riding in the pickup bed and both were taken to the Jackson hospital.

The party took place at the end of Wilderness Road near the Teton Wilderness.

‘‘It definitely was attended by more than this group of people,’’ Skaggs said.

Most of the pickup passengers were seasonal workers in Jackson Hole.
