The fire happened Oct. 7 at a house where several members of a fraternity lived. Cody Pilkington and Mark Davis were not able to escape.
Autopsy reports show Davis died from smoke inhalation, but he also had a blood alcohol content of 0.11.
Fire investigators say that may have slowed his reaction time and made it harder for him to get out of the house.
Pilkington had no alcohol in his system.
