Authorities said the fire was set on two sets of stairs outside the home to prevent anyone from escaping.
According to records, Hawthorne's son's girlfriend said she received text messages less than two hours after the fire, one of them reading, "Tell (him) we burned down his mama's house."
Police say there is video of two people at the fire scene, but only Thompson was arrested and charged with capital murder.
