According to information released by the Georgia Bureau of Investigation, Jerand Edward Ross ran out the back of an apartment during the raid and made it about 200 feet before encountering Barney. Ross shot Barney before a Clayton County officer returned fire.
Ross was critically wounded and, as of Friday evening, remained hospitalized. He has been charged with murder.
Barney, who was not wearing a bulletproof vest, died during surgery at Southern Regional Medical Center. Clayton County police have released little information on the no-knock search warrant that sent him into harm's way. On Saturday, Channel 2 Action News reported that two men were arrested on drug charges during the raid. They've since been released on bond, according to the station.
In the days since Barney's passing, colleagues, friends and loved ones have described the 50-year-old as "a cop's cop" and a family man, tough but caring. He was Riverdale's first black police chief (an interim role) and served at the school resource officer at Riverdale High, among many other roles.
“He loved his job and took great pride in protecting and serving the City of Riverdale,” the Barney family said in a statement. “… Greg was a great husband, loving father to twin boys and a caring friend. We will miss him dearly.”
