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 Hwy. 16 in Sparta, which is in Hancock County.

“It’s an ongoing investigation, and we can’t discuss details,” Bankhead said. “Sometimes these things take a while to resolve.”

As part of the case, the GBI has conducted road checks and interviews, among other measures, Bankhead said.

Agents also have been checking into Garner’s background “to see if there might be anybody that might have a grudge,” he said.

The GBI was called in at the request of the sheriff’s office in Hancock County, where Bankhead has said murders are rare.

According to the GBI, an autopsy was conducted Monday at its medical examiner’s office in Decatur.

The cause of death is being withheld due to the investigative value, Bankhead said, though he added “it was obvious” that Garner had been killed.

He had last been seen alive at 4 p.m. that day.

Garner and his brother stayed at and operated the well-known area business during hunting season, Bankhead said.

According to his obituary, Garner was a 50-year member of Cumming Second Baptist Church who loved hunting, fishing and taxidermy.

Funeral services were held Saturday. His immediate survivors include his wife, son, several stepchildren and numerous grandchildren and great-grandchildren.
