The fire happened around 9 a.m. Saturday on the second floor of the two-story home. Emergency crews said they there were no flames or smoke visible when they arrived, but inside they found heavy smoke and the body of 38-year-old Tallmadge D’Elia. St. Pete Fire Rescue says D’Elia had severe facial injuries, believed to be a result of his vape pen exploding near his face.
