Powell said Cordero was expected to be released from the hospital Thursday. The driver of the second car, 40-year-old Monica Hood, has already been discharged from the hospital, Powell said.
Meanwhile, police continue to investigate the crash. Some witnesses described a third car that may have contributed to the crash and then sped away. Powell on Thursday would not confirm whether police believe that happened.
"We're not ruling it out, either," Powell said. "We're looking at all different angles."
Armijo was driving the Honda Civic north on 5600 West through the intersection with 4100 South when, for unknown reasons, the car veered into the southbound lanes, colliding with Hood's Toyota Corolla. Some witnesses said Armijo swerved to avoid a minivan that ran a red light.
Granite School District spokesman Ben Horsley said grief counselors were at Hunter High on Thursday. Horsley didn't know whether the crash will have the district reconsider letting students leave campus for lunch, seminary and other activities.
"It's too early," Horsley said.
Horsley said in the 1990s students weren't allowed to leave campus during the school day and that policy was unpopular.

An account to help with funeral and medical expenses of the crash victims has been established at America First Credit Union. Donations can be made in the name of each of the students.
