Investigators are trying to determine why an 11-year-old boy was driving a car that ran a stop sign in California and crashed into another vehicle, leaving him and two others dead.
The collision killed Jose Manuel Silva Covarrubias, his mother, Maria Silva, and six-year-old sister, Elizabeth Silva Covarrubias.
California Highway Patrol investigators have not been able to interview the car's lone survivor to determine why the boy was driving on Tuesday night. Family friend Froylon Gonzalez remains in critical condition.
Investigators say Jose was driving the 1993 Honda when he ran a stop sign in Tulare County and was hit broadside. The driver of that vehicle had minor injuries.
A Honda, with eleven-year-old Jose Covarrubias behind the wheel, ran a stop sign in Porterville, California colliding with a Ford around 7:30 P.M.

The eastbound 1993 Honda was sideswiped from the driver's side by a southbound 1999 Ford, killing Jose.  His sister, 6-year-old Elizabeth Covarrubias, and mother, Maria Covarrubias, were killed when they ejected, as they were not wearing seatbelts.  Family  friend Froylon Gonzalez was sent to the hospital with serious injuries, and the driver of the Ford, Charles Seguin, sustained minor injuries.

Felipe Gonzalez, Froylon's brother, said the family was returning from Jose's soccer team practice. He also added that he had never seen Jose drive before. Gonzales was the lone survivor of the Honda and has not yet been interviewed.

The accident occurred at a rural intersection and it did not appear to law enforcement that drugs, alcohol, or weather were a factor in the collision.

The bodies will be buried in Mexico near where the father lives.
