A bus veered off a highway and crashed in central Pennsylvania early Sunday, killing two people and injuring 31.
Investigators were having difficulty piecing together what happened because most of the passengers were Asian and did not speak English, state Trooper Terry Jordan said.
The name of the company that operated the bus was not immediately known.
One victim was listed in serious condition and six were in guarded condition, Clearfield Hospital nursing supervisor Ann Langenbacher said.
The injured range in age from a toddler to a 50-year-old.
