COVINGTON, Ga. — Clues related to at least one homicide were found in Lake Varner this week.

Meanwhile, Monroe police urged their suspect to surrender.

“Over the last few days, we have been in and around Lake Varner in Newton County acting on anonymous tips related to the Bernard Barnes and Shaun Barfield murders that took place in Monroe, Georgia, on the 5th and 6th of May,” Keith Glass, the director of the Monroe Department of Public Safety, said in a statement.

“Our efforts have yielded items believed to be related to one if not both cases.”

Police centered their search off the Flat Rock Road bridge.

Darrin Bernard Barnes, 43, of Duluth, died when a fight broke out at a party at about midnight May 5 on Tanglewood Drive in Monroe.

At about 6 p.m. the next day, 33-year-old Shaun Barfield was found dead on nearby Tanglewood Lane after a shooting.

Glass this week urged McKibben to surrender to law enforcement now.

“If you know Mr. McKibben and can contact him, please advise him to turn himself in,” Glass said. “It’s in his and the public’s best interest that he do so now.”

McKibben is 5 feet 7 inches tall. He weighs 145 pounds, is black and has black hair and brown eyes.

Glass has said McKibben should be considered armed and dangerous, and anyone with information on McKibben’s whereabouts should call 911.

Anyone with information on the Barnes or Barfield cases is asked to contact Detective Chris Cannon at ccannon@monroega.gov or 770-266-5183, or the Athens office of the Georgia Bureau of Investigation at 706-552-2309.

Glass said he was “very appreciative” of the support of the GBI, Georgia Department of Natural Resources, the sheriff’s offices in Hall and Newton counties and the Walton County district attorney’s office.
