A 19-year-old woman is in critical condition after the car she was riding in was in a rollover crash Thursday morning.


Shortly after 1 a.m. on June 3, San Bernardino County Sheriff's Department deputies were called to Cottonwood Avenue, near the intersection with Ranchero Road, investigating a traffic collision.


According to a release issued by the Hesperia sheriff's station, a 17-year-old driver, driving a 1999 Infiniti, was driving south on Cottonwood at a high rate of speed. The driver reportedly failed to stop at the Ranchero intersection, hit a dip in the intersection and his vehicle became airborne. The vehicle crossed over the centerline into the oncoming traffic lane, left the roadway, entered a field and rolled over several times.


In the vehicle at the time were three other males, ages 17 through 20, and the driver's 19-year-old sister.


The woman, who was reportedly not wearing a seat belt at the time of the crash, was ejected from the vehicle, and she received severe head injuries. The victim was airlifted to Loma Linda Medical Center, where she is listed as being in "extremely critical condition" as of Thursday afternoon.


The other occupants received minor injuries and were treated at local hospitals.


Sheriff's investigators believe that none of those in the vehicle were wearing seat belts at the time of the crash. Investigators do not yet know if drugs or alcohol were a factor in the crash.


Anyone with information about this case is asked to contact the Hesperia station at 760-947-1500 or WeTip at (800) 78-CRIME.
