GENEVA, Ala. (AP) - Florida investigators have charged a man in connection with a missing woman, whose burned car was found in southeast Alabama with a body inside.

The sheriff of Holmes County, Fla., Tim Brown, said Tuesday that 34-year-old Johnny Mac Calhoun of Black, Ala., was charged with tampering with evidence. He said the charge stems from a missing person report on Mia Chay Brown, 24, of Bonifay, Fla., and more charges may be filed.

The sheriff in Geneva County, Ala., Greg Ward, said a burned Toyota Avalon believed to be Brown's was found Monday in a wooded area of Oak Grove and a body was in the trunk. Forensic experts are working to identify the body.

Brown was last seen Thursday at a food store where she worked in Esto, Fla.
