Tragic: Elvira Campos, 10, was shot to death on Saturday night after gunmen opened fire on her family's home
A 10-year-old girl was shot dead while watching TV after gunmen opened fire on her family's home.
Elvira Campos was killed when at least two suspects sprayed the property with bullets, in North Highlands, near Sacramento, California.
Her father and mother were also injured in the attack, on Saturday night.
At least two gunmen are believed to have carried out the shooting, which took place at around 10.30pm.
About a dozen shots are believed to have been fired at the home from two different weapons.
Four holes were clearly visible in the living room window of the property, where the girl is believed to have been sitting.
Bullet holes could also be seen in the property's front door and in the frame around the front window.
Sheriff's spokesman Jason Ramos said the youngster's parents are expected to recover from their wounds, the

Detective Scott Swisher said the family were innocent victims and that they were not involved in any disputes that the police are aware of.
