A Williamson County jury on Thursday sentenced Royal Anthony Williams to six years in prison for injury to a child.
The jury on Wednesday found Williams guilty of the charge after he was accused of beating his girlfriend's toddler when potty-training the child Oct. 30.
Williams, 24, could have received up to 10 years in prison. He must serve three years before he is eligible for parole.
According to the arrest affidavit, Williams struck his girlfriend's son, then 16 months, on his buttocks, legs and abdomen with a belt after the child soiled his diapers.
An examination later at Dell Children's Medical Center in Austin revealed that the child had injuries to various parts of his body including an eyelid, his abdomen, both legs, his hand and wrist and buttocks. The prosecutor told the jury that the strikes left scars on the child's buttocks.
