WINDER – (WAOK/AJC) – Authorities say twin brothers are being held separately after police found a dead man’s body buried in concrete at their father’s house in Winder. 31 year old William and Christopher Comier, who recently moved back to Georgia, from Florida, told their father that they buried their friend’s dog in the backyard, but a call from someone in Pensacola, Florida raised suspicion, about a missing man last seen with the Comier brothers. Police dug up the yard on Sixth Avenue on Monday and found the corpse in a plastic container encased in cement. An autopsy is being performed to identify the man and determine the exact cause of death. The Georgia Bureau of Investigation is now involved in the case. Investigators are trying to determine if the body is that of 30- year old Sean Dugas, a reporter for a Pensacola newspaper, whose friends reported him missing, nearly a month ago. The brothers are being held on charges of concealing a death, but could be facing more charges.
