WINDER, Ga. (AP) - An autopsy shows that a man found entombed in concrete and buried in the back yard of a northeast Georgia home died from multiple blows to the back of his head.

Investigators unearthed the body Monday after being directed to the Winder house by police in Pensacola, Fla., who have been investigating the disappearance of 30-year-old Sean Dugas.

Georgia authorities have arrested 31-year-old twins Christopher and William Cormier and charged them with concealing a death. It wasn't known whether they have attorneys.

Winder police Officer Chris Cooper tells The Athens Banner-Herald (http://bit.ly/OT0CFr ) that the probe stretched into nearby Gwinnett County on Tuesday. Investigators went to the county northeast of Atlanta to check on a U-Haul truck or trailer that had been rented by two people of interest in the death investigation.
