Sheriff's office investigating after 4-year-old boy thrown off Montesano bridge into river

MONTESANO -- The Grays Harbor Sheriff's Office is investigating after a 4-year-old boy was thrown off a Montesano bridge into a river.

Sheriff's deputies were called to the Devonshire Bridge over the Wynochee River in Montesano earlier this week after bystanders witnessed the boy being thrown off the bridge and called police.

The boy survived the fall. It was not immediately known if he suffered any serious injuries.

Deputies interviewed witnesses and the boy's mother. Deputies said Saturday they've recommended the Grays Harbor Prosecutor's Office charge the boy's mother with reckless endangerment and another man with reckless endangerment and criminal trespassing.

All of the charges are misdemeanors, deputies said. Child Protective Services has also been notified of the event.

Video of the boy being thrown was posted to Facebook Thursday and shared more than 1,000 times. Many commenters expressed outrage.
