The victims of a multiple fatality collision in northwest Arizona Sunday were residents of China. The Department of Public Safety said Tuesday that the dead included a 52-year old man who was driving a van and three passengers, two 52-year-old women and a 19-year-old woman.

DPS said the van had been southbound on U.S. 93 and was trying to turn west to access Pierce Ferry Road when it was demolished by an oncoming tour bus belonging to the Dallas Cowboys football organization.

The organization has said that no players were aboard the bus that was transporting staff members to a promotion stop in Las Vegas. Nobody aboard the bus required medical attention.

DPS has not indicated whether the victims were taking Pierce Ferry Road to visit the Skywalk at Grand Canyon West

“Any loss of life while traveling on the road is heartbreaking and tragic,” said Lt. Col. Dan Lugo, Assistant Director of the Highway Patrol Division. “When driving on our highways and byways drivers need to always be cautious and aware of road and traffic condition around them.”

Cowboys owner Jerry Jones also expressed remorse in a statement released Monday.

“We as an organization are deeply saddened, and our thoughts, prayers and concerns at this time are with the family members and loved ones of all who were lost,” Jones said.
