FONTANA, Calif. (AP) — Police say four people, two of them children, have been found killed in a Southern California home.

Fontana police Sgt. Doug Imhof tells KNBC-TV and KABC-TV that a 16-year-old boy called police Monday night to say his family members were injured or killed in the house.

Imhof told the TV stations the bodies of a boy about 10 years old, a girl about 12 years old and a man and woman each about 35 or 40 years old were found inside the house and it appears they all lived there.

Fontana police Chief Rodney Jones told KNBC earlier that "multiple homicides" had occurred inside the home.

The home is in Fontana, a city of about 200,000 people in San Bernardino County about 50 miles east of downtown Los Angeles.
