The Suburban had nine people on board when it was struck head-on by a Buick passenger vehicle, DPS said.
Angel Mesa, 41, from Eloy, Ariz., was driving the Buick, with Nicole Vidal, 33, as a passenger. They were both killed in the collision.
Rodney Palimo, 45, from Sells, Ariz., was driving the Suburban. Kathleen Palimo, 43, was a passenger in the Suburban.
Seven other passengers in the Suburban were Guatemalan nationals, according to a news release from DPS. Four of the men were killed, and three were injured.
DPS said it's not known at this time why the Buick went "left of center" and collided with the Suburban.
DPS said initially nine had died in the crash, but tweeted an update later Thursday saying three people involved in the crash were in the hospital, one being in extremely critical condition.
Troopers are working with the Department of Homeland Security to attempt to identify and make next-of-kin notifications for the men from Guatemala, which DPS says will take time to complete.
