A GoFundMe page set up to help the boy's mother with funeral expenses says, "Brenym was smart, enthusiastic, always smiling with the biggest heart. There wasn't a single room he couldn't light up with his smile, or a story he couldn't tell you that would make you laugh."

At this time, no motive for the attack has been released.

Child Protective Services says they are investigating McDonald's death.

The agency says that they do not have any history with the family.

On Monday, the boy's great-grandmother told FOX 4 McDonald and his parents were temporarily living with Hughes.

Hughes did have a previous arrest and conviction for driving while intoxicated.

He is currently being held at the joint detention center at the North Richland Hills Police Department.

There were extra counselors on hand as Birdville ISD students returned to school on Tuesday for the first time since the holiday break.

The district says campus staff spent Monday calling parents of students who were in the same grade level as McDonald.
