The vehicles collided head-on.
Allison and her passenger, a 42-year old woman from Yuma, remained trapped in the sedan until extricated by Imperial County fire personnel, the release states.
The 42-year-old woman sustained fatal injuries, including blunt force trauma to her chest and head and fractured femurs. Her name was not released pending identification and notification of next of kin, said Chief Deputy Coroner Sgt. Rick Macken.
Allison was transported to Pioneers Memorial Hospital in Brawley with major injuries, including a fractured hip and chest and head trauma. She was transferred from Pioneers to another hospital, although a Pioneers staffer did not know where she was taken.
Nolasco's SUV came to rest 50 feet west of the impact area.
Nolasco sustained moderate injuries, including lacerations and pain to his arms. He was transported to El Centro Regional Medical Center, where he was treated and released.
Nolasco's wife, Juana Nolasco, 43, also of Heber, was trapped in the right front seat of the SUV until being extricated by fire personnel. She sustained major injuries, although the press release did not indicate to which hospital she was taken.
Another passenger in the SUV, Isabel Dominguez, 74, of Heber, sustained major injuries, including fractured ribs and pain to her right ankle. She was transported to Pioneers where she was admitted to the intensive care unit for observation.
Five other passengers in the SUV sustained minor to major injuries and were transported to local hospitals. Their names were not available from the CHP.
El Centro and Winterhaven CHP units responded as did U.S. Bureau of Land Management rangers, the Imperial County Fire Department, Gold Cross paramedics and Brawley Fire Department.
