16-year-old charged as adult with murder in California police officer's killing

A 16-year-old has been charged as an adult with murder in the shooting death of a Southern California police officer in what investigators called a botched robbery.

The teen, Abel Diaz, was charged Friday with murder in the death of Downey police Officer Ricardo "Ricky" Galvez.

Diaz was set for a court appearance later Friday, when an attorney will be appointed to his case. He faces life in prison if convicted.

Two other men arrested in Galvez's killing are expected to be charged Monday. Their names haven't been released.

The 29-year-old Galvez was in plainclothes in the driver's seat of his personal car at the end of his shift Wednesday night when he was shot.

The former Marine, a five-year veteran of the police department, died in his car.
