A mother faces felony charges for the traffic collision that injured three of her children, including an infant who was unrestrained.
Mayra Alejandra Gonzalez, 29, was driving her Chevy Suburban Monday morning when she drove into oncoming traffic on Camino Del Norte and collided head-on into a Jeep Liberty.
Gonzalez' 9-month-old baby, who was being held by an 8-year-old girl at the time of the crash, suffered life-threatening injuries.
CHP investigators said the force from the crash threw the infant into the windshield.
When San Diego Fire-Rescue crews responded to the crash at about 4:30 a.m. witnesses had already pulled the baby from the crash but the child was not responsive.
The 8-year-old girl and a 2-year-old girl suffered minor injuries. All three children are the driver's daughters, officials said.
The driver of the Jeep, a 57-year-old man, also suffered serious injuries.
Gonzalez was transported to Palomar Hospital where she was placed under arrest Thursday on suspicion of felony DUI, felony child endangerment and driving on the wrong side of the road.
She is still receiving treatment at the hospital, SDPD said.
