Sarah Gomez, 19, and her 21-year-old boyfriend were at a family gathering Monday night and had both been drinking.
They were driving home a few streets away when the two began arguing. When they were in the driveway of their home, the boyfriend got out of the vehicle while carrying the couple’s 7-month-old daughter.
According to police, that’s when Gomez, who was in the driver’s seat, intentionally drove into them.
“I believe, at this time, that the father and the child were either at the side of the car or at the back of the car, I’m not sure. It did happen near the apron of the driveway and getting into the street area,” said Ontario PD Sgt. Jeff Higbee.
The boyfriend was taken to the hospital to be treated for scrapes and bruises, but the 7-month-old was transported to the hospital where she would later die from her injuries.
Gomez was initially charged with DUI resulting in great bodily injury or death and vehicular manslaughter with gross negligence.
Those charges have since changed to suspicion of murder and attempted murder now that investigators believe she intentionally hit the pair. Gomez is currently in the San Bernardino County West Valley Detention Center.
