Georgia police have unearthed a body that was entombed in concrete, stuffed inside a plastic storage container, and buried in a back yard. They believe the remains could be those of a missing Florida man.

Police in the northeastern city of Winder arrested 31-year-old twins Christopher and William Cormier on Tuesday, a day after the body was found. They were charged with concealing a death.

It wasn't immediately known whether they have attorneys. Winder police weren't ruling out additional charges. The Georgia Bureau of Investigation was assisting in the investigation.

Investigators were directed to the house about 45 miles northeast of Atlanta by their counterparts in Pensacola, Fla., who have been investigating the disappearance from that city of 30-year-old Sean Dugas. Dugas had not been heard from since Aug. 27.
