The boy, Johnathan James died July 25 after water was kept from him for five days while temperatures soared to 100 degrees or more each day, police said. The boy's dad, Michael Ray James, and stepmother, Tina Alberson, both 42, were jailed after being charged Thursday with injury to a child causing serious bodily injury.
Johnathan's twin brother, Joseph James, and a 12-year-old stepbrother were not injured and are staying with relatives.
Attorneys for the dad and stepmother did not immediately return calls seeking comment left at their offices Saturday night.
Joseph told the Dallas Morning News (http://dallasne.ws/qOpWSJ) that his parents put Johnathan in a room without air conditioning and told him to stand by the window. Joseph said that on the day Johnathan died he had peanut butter stuck in his throat but his parents wouldn't let him wash it down.
"They still wouldn't let him have water," Joseph said.
Joseph told the newspaper he wanted to help his brother but was worried he would face similar punishment.
"I wanted to do something, but I couldn't," Joseph said. "I couldn't do nothing because I would get in trouble."
Police documents show the boy suffered until he collapsed at his father's Red Bird home and hit his head on the floor. He was taken to a hospital, and authorities say Michael James told authorities there that Jonathan was sick. Medical staff were unable to revive the child.
The boys' grandmother, Sue Shotwell, said Jonathan was easy-going and never held a grudge.
"This kid, if you know Jonathan, he could forgive you for no matter what you did," Shotwell said. "You could ground him, and he would say 'I love you, Mimi.'"
