NEWPORT BEACH (CBS) — The Irvine dad accused of throwing his 7-year-old overboard from a Newport Beach boat was convicted Monday of felony child abuse and resisting arrest charges.

Sloan Steven Briles, 35, pleaded guilty to a court offer to one felony count of child abuse and endangerment and one misdemeanor count of resisting an officer.

He was sentenced to three years of formal probation, one year of a child abusers treatment program, and 180 days in a Veterans Administration residential treatment program.

Briles reportedly slapped his son while aboard a tour boat and tossed him into Newport Harbor on Aug. 28.

Orange County Sheriff’s spokesman Jim Amormino said that the boy was crying about an argument between Briles and his father’s girlfriend before the incident occurred.

“Three boaters that were nearby came to the boy’s rescue,” said Amormino. “The father did eventually jump in, but by that time the boy was rescued by a boater.”

Briles later became aggressive with authorities who later boarded the boat to arrest him, Amormino said.

Both the boy and his brother were later returned to their mother’s care.
