On the way to hospital, the child later informed a Department of Children and Families investigator that May had allegedly taken boiling water from the stove top and poured it on him, because he accidentally peed on the floor.
May was arrested and charged with causing great bodily harm.
May was previously arrested back in January 2018 after his own three-year-old daughter told officers she was frequently beaten with a belt, and was once put into an oven.
Photographs showed the extent of her injuries, including several contusions and swelling to her head, a 6" scar on her back, and abrasions on her ear, leg, hands and feet.
May denied the accusations, claiming his ex-girlfriend made them up because he wouldn't pay child support.
He pleaded not guilty, and prosecutors dropped the case; records from the state attorneys office cited problems with the case, in that the girl was hard to understand, there were no witnesses, and they couldn't prove when the injuries occurred.
