A body found encased in concrete in a plastic container and buried in a back yard in Georgia has been identified as a missing Florida reporter, police said. An autopsy found that Sean Dugas, who was reported missing Sept. 13, died of blunt force trauma about a month ago, the Pensacola (Fla.) News Journal reported Friday. Dugas, a former reporter for the News Journal, was last seen Aug. 27. His remains were found Monday in Winder, Ga. Georgia police have arrested twin brothers William and Christopher Cormier and charged them with murder, although it is not known where Dugas died. The Georgia Bureau of Investigation said Dugas\' remains had been identified through dental record and facial bone CT scans, CNN reported. The body was found in the back yard of a home owned by the suspects\' father, who has not been charged. Authorities believe the body was buried about three weeks ago, about the time they arrived from Florida. Dugas\' girlfriend noticed him missing Aug. 27, but did not call police until Sept. 13.
