A 41-year-old Missouri man has been charged with child abuse after allegedly assaulting his teenage son so severely that the boy suffered a seizure, reportedly over a phone call the man deemed disrespectful.According to a probable cause affidavit, Matthew Proctor is accused of punching his son multiple times in the face and continuing the assault after the teen fell to the ground.The heavily redacted affidavit outlines that the incident took place at the home of one of the mothers of Proctor’s children last Tuesday, as the children were preparing for a planned trip to the Worlds of Fun amusement park in Kansas City.Proctor reportedly became enraged after calling the home that morning and feeling disrespected during the call. He allegedly threatened to come over, saying he would “beat someone’s a**” upon arrival. All of the children involved are under 18, and one later told deputies that Proctor had previously “punched the air out of his lungs.”When Proctor arrived at the house, the teenage boy came outside and reportedly shouted at him. In response, Proctor allegedly struck the boy in the face, causing him to fall and begin convulsing.Read more: Caught On Cam: Man punches father over property disputeDespite this, Proctor allegedly continued to hit him.
