It's understood that the child's mother left the group of children in a room with Knuth for around 10 minutes before she hears a loud noise and ran back inside.
That's when she discovered her son had been shot in the knee and his friend's had blamed Knuth for the injury.
Knuth, who was intoxicated at the time, claimed that he had gone to bed and had no memory of injuring the boy.
However, according to a report from Fox 35 Orlando, when police arrived, Knuth muttered that he was going to child for having shot the child.
He has been charged with neglect of a child with great bodily harm and using a firearm while under the influence.
