The blaze on the 1500 block of Martin Luther King Drive spun out of control, causing the entire house to burn down. Brown is now in the hospital with burns on 85% of his body.
Police say he had a confrontation with his wife before the blaze, but she was not home at the time the fire was set. Brown now faces multiple felony charges including arson.
Grambling and Ruston police are leading the investigation.
