A truck jammed with as many as 60 illegal immigrants crashed and rolled in a remote part of central Arizona on Sunday morning, killing four and injuring many.
The truck was carrying possibly 50 to 60 people, many of whom ran into the desert, said Vanessa White, spokeswoman for the Pinal County Sheriff's Office. The driver is believed to be among them.
Investigators believe the people on board were illegal immigrants, White said.
Four men were pronounced dead at the scene, while 27 survivors were taken to hospitals. White did not know their conditions.
Speed and possibly alcohol are believed to be factors in the 5:30 a.m. crash near the town of Arizona City, about 60 miles south of Phoenix, White said. She did not have details on the truck.
Such crashes involving suspected illegal immigration are not uncommon. A collision in Texas killed three people just last month.
