Investigators in Wyoming began sifting through the wreckage inside a highway tunnel on Saturday after smoke, hazardous chemicals and structural concerns prevented them from determining how many people may have died in the fiery pileup.
At least two people were killed and five others seriously wounded by the multi-vehcle crash on Friday, said Maj. James Thomas of the Wyoming Highway Patrol. The crash took place in the westbound tunnel of Interstate-80 under Castle Rock, a snow-covered sandstone formation that looms over the town of Green River in the state's southwest.
