Utah ? A ninth person died Monday after a bus carrying skiers home from a Colorado resort plunged off a damp, twisting highway in southeastern Utah and landed 41 feet below with its tires ripped away and the roof destroyed.

“The bus looked like a convertible,” said Jim Hook, the fire chief in Bluff.

Those killed included four teenagers, officials said. About 20 other people from the Phoenix area were injured Sunday night, some seriously, authorities and hospital officials said.

“There were lots of head injuries, glass, broken limbs. … Everybody was just looking for help. We had to sort through it,” Hook said.
