A Dallas Cowboys bus and a van collided Sunday on an Arizona highway, killing four people in the van, authorities said.
The Arizona Department of Public Safety said at 1:40 p.m. the van, with a driver and three passengers, was traveling southbound on State Route 93 near Pierce Ferry Road. The bus was traveling northbound on State Route 93. The van turned left across lanes to access the road and the two vehicles collided in the intersection.
Three females and a male inside the van died at the scene.
As part of the investigation, the bus will be inspected by commercial vehicle inspectors.
"All on the bus came through OK with some bumps and bruises," Cowboys spokesman Rich Dalrymple said in an email.
Dalrymple said the bus was only carrying members of the franchise's staff but would not say how many. There were no players on board.
Mickey Spagnola, a columnist for the team's website, has been writing for the past week about traveling on a Cowboys bus with a driver, the team mascot and videographer. On his Twitter page, Spagnola tweeted before 2 p.m. that the bus was 80 miles outside of Vegas.
The bus was on its way to a Dallas Cowboys fan event in Las Vegas.
