Courtney Allen Thompson is accused of setting fire to a home in the 700 block of 29th Street near Winnie Street at about 1 a.m. on Feb. 29.
A mother, identified as 55-year-old Renita Hawthorne, was trapped inside her home and died trying to escape. Five others, including two firefighters, were taken to the hospital to be treated for their injuries.

ABC13 obtained court documents outlining what allegedly happened.
Police believe Thompson set the fire because Hawthorne's son did not pay for marijuana.
According to the report, the victim's son told detectives he had been receiving threats for a while over the drug debt.
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.
