Irvine man pleads innocent to throwing son overboard

A father accused of throwing his son over the side of a tour boat in Newport Harbor pleaded not guilty in court Monday.

Sloane Briles, 35, is charged with child abuse and endangerment.

Investigators say an argument between him and his girlfriend on a tour boat last month upset his 7-year-old son.

Passengers say Briles threw the boy overboard because he wouldn't stop crying.

The boy was rescued.

If convicted, Briles faces up to six years in prison.
