Authorities remain tight-lipped about the investigation into the death of a Cumming man a week ago at his deer-processing business in middle Georgia. No arrests have been made in the Dec. 2 slaying of Nelson Garner, 60, said John Bankhead, director of public affairs for the Georgia Bureau of Investigation. Garner’s body was found by his brother about 9:30 p.m. at Garner’s Grinder on Ga. 16 in Sparta, which is in Hancock County.
