BAKERSFIELD (AP) — Kern County sheriff’s deputies won’t face criminal charges over the death of a man they beat during an arrest.

District Attorney Lisa Green announced Friday that investigators found law enforcement used reasonable force and a coroner has ruled that 33-year-old David Silva died of heart disease.

Deputies confronted Silva last May while answering a report of an intoxicated man. The 260-pound Silva was struck with batons and bitten by a police dog during a protracted struggle.

He later complained of breathing problems and died.
