how did ed gein kill his brother

Ed Gein did not kill his brother Henry. Henry Gein died in 1944 under mysterious but officially accidental circumstances during a fire near the family's farm in Plainfield, Wisconsin. Henry and Ed were reportedly burning vegetation when the fire grew out of control. Henry's body was found with bruises on his head, but the death was ruled an accident, likely due to asphyxiation from the fire, and no autopsy was performed. Ed denied harming his brother, and there is no evidence or confession proving Ed killed Henry. Speculation and dramatizations, such as in TV shows, have suggested otherwise, but legally and factually, Henry's death remains an accident, not a murder by Ed Gein.
