KNOXVILLE, Ga. (AP) — Authorities in Georgia say the grave of a Confederate soldier has been dug up and investigators are working to determine whether anything has been stolen.

Crawford County Sheriff Lewis Walker on Thursday said a grave is at the Old Bethel Church Cemetery in Knoxville and belonged to James Nichols.

WMAZ-TV reports historical records show Nichols was captured in Vicksburg, Mississippi, on July 4, 1863, and died Nov. 9, 1866. Crawford told the Telegraph of Macon that Nichols was a first lieutenant in the Confederate Army and the suspects may have been looking for artifacts that were buried with him.

Walker says authorities are trying to locate Nichols’ relatives and the Georgia Bureau of Investigation has been called to help inspect the grave’s contents.
