ST. GEORGE, Utah (KDXU) - A St. George woman has been charged with criminal homicide after a crash on I-70 early Sunday killed her 12-year-old child and left her 9-year-old fighting for her life.

State troopers say they found the vehicle on the right shoulder of the interstate with both of the children ejected from the car and the driver still in their seat.

Charging documents state 33-year-old Cami Jean Aparicio, the driver and mother, only had minor injuries and she appeared to be extremely intoxicated.

Aparicio apparently hit a semi-truck head on.
