Trucker pleads guilty to double deadly DUI charges, faces 20 years

FRESNO, Calif. -- Truck driver Alonso Hernandez pleaded guilty to charges in a hit and run DUI crash that killed a mother and her 14-year-old son in July 2014.

The Santos family was traveling home from working in the fields when a rear-end collision crushed the back of their car.

"I did not realize what had happened," said Efrain Cortez Santos, the family patriarch in December, through a court interpreter. "I just felt the impact and I was not able to get out."

Santos' daughter Reynalda was in a coma for two months after the accident. She still has memory loss and still has trouble walking.

Police arrested Hernandez after the crash. They say the L.A. native had a blood alcohol content of .14% as he drove a load of onions through the Central Valley. And Hernandez didn't stop even after the crash, according to investigators.
