WILLOW BEACH (AP) - A charter bus carrying tourists back to Las Vegas from the Grand Canyon crashed on an Arizona highway, killing the driver and injuring more than 20 passengers, six of them seriously, authorities said.
The bus was northbound on US 93 on Friday night, nearing the Nevada state line, when the driver suffered a physical problem and lost control, the Arizona highway patrol said. The company that offered the tour said the driver may have suffered a heart attack.
The vehicle hit a ravine, tore up a small hill, and then bounced and lurched over rough terrain for more than 700 feet before stopping, damaging the front end but remaining upright, patrol spokesman Carrick R. Cook said.
"We believe the driver experienced some sort of the medical condition and he just went off the road," the patrol said in a statement. No other vehicles were involved.
All 48 passengers were injured, but 27 of them were walking wounded with mainly bumps and bruises, Cook said.
"The passengers were pretty much bouncing around," he said.
The six most seriously hurt were flown by helicopter to University Medical Center in Las Vegas, while 15 others with less severe injuries were rushed to area hospitals by road.
UMC spokeswoman Danita Cohen said the six were being treated for nonlife-threatening injuries, such as broken bones and lacerations. She described them as being mostly over 50 years old.
Cook said most of the passengers appeared to be from Asia or Europe, but he didn't have details.
