HARRIS COUNTY, Texas -

A Harris County man accused of beating his girlfriend's son faced a judge Friday.

Byron Craig Mathis is charged with injury to a child. The incident happened on February 4 at a residence on 5214 Southlea Street in southeast Houston.

Court records show that Mathis, 28, struck a 14-year-old boy with his hand after the boy said to his mother that he wasn't feeling well and didn't want to go to school.

That's when Mathis came in the room and told the boy to get up, according to court records. When the boy refused, Mathis became angry and slapped the boy, who was lying on the bottom half of a bunk bed. Authorities say Mathis then dropped the top bunk on the boy and hit him multiple times with a closed fist.

Court records show that the boy said he was punched about 20 times, and that he was in pain and thought he would become unconscious during the attack.
