Two young adults are dead after a driver lost control of her car and rolled nearly four times, according to the San Bernardino County Sheriff-Coroner Department.


Amber Siegrest, 22, of Hesperia, was heading south on I Avenue in her 1991 Ford Bronco around 2:23 a.m. Sunday when she drove onto the east shoulder and overturned three to four times, coming to a rest near I Avenue and Alston Street, officials said.


The two rear passengers died shortly after the crash.


The coroner pronounced Anthony Kaminski, 22, of Victorville, dead at the scene. Truman Switzer, 24, of Apple Valley, was driven to Desert Valley Hospital and died around 3:42 a.m. before he could be airlifted to a trauma center, officials said.


Front passenger Mark Beltran, 31, of Oak Hills, suffered minor injuries and was released from Arrowhead Regional Medical Center several hours after the crash, officials said.


As of late Sunday, Siegrest was still in the hospital with unknown injuries.


The Sheriff's Region II Major Accident Investigation Team is investigating the collision. Officials have not confirmed whether alcohol played a role in the accident.
