A Missouri mother was furious after a viral video showed a teenager holding a gun at her 13-year-old son’s head.

The video, which circulated on social media, showed the 13-year-old boy on his knees and being yelled at by a few boys demanding him to kiss their feet. A boy was seen pulling out a gun and pointing it at the boy’s head. The gun was pulled away and the boy was seen being punched.

Emily Bridges told FOX 4 KC she was upset when her son came home with bruises on Saturday. The mother told the station her son is on the autism spectrum and she didn't know what happened until her other son showed her a video of the incident.
