Terrifying moment a 4-year-old boy was thrown off a 27-foot bridge into a river

A Washington state mother stood by and watched while a man, possibly her boyfriend, threw her 4 year old son off a 27 foot railroad bridge into the Wynoochee River in Montesano.
An eye witness, Kaylub Fawley, who saw the couple and the screaming child knew something wasn't right and started recording the incident. 
Another eye witness, Brianna Jones said 'He was screaming and crying, it was terrible,'

Kaylub Fawley, who recorded the scene and posted the video on Facebook, said:

'As soon as he hit the water, my heart sank, I felt so bad, I didn't know what to do. 'I saw the little boy and I had a gut feeling,' he added. 'I was like alright I got to start recording this, and as soon as I started recording, he went off.'

Fortunately, the little boy survived the fall but they didn't say if he suffered any injuries or not.
Kaylub said:

The Grays Harbor Sheriff's Office has charged the boy's mother and the male acquaintance, neither of whom have been named, with reckless endangerment charges.

The man has also been cited for trespassing, as the bridge is private property, KOMO News reported.

Child Protective Services is also involved in the investigation, KING 5 reported. The local district attorney has not decided if the pair will be charged yet.
