Authorities say Varner is known by his nickname, “Calico.” He was still at large at mid-morning Thursday.
Wilder was arrested Tuesday night in Union City on different charges, College Park police detective Sgt. Eddie Atkins said.
“We had a tip that he had information,” Atkins said of Wilder. “Detectives interviewed him and he confessed.”
During the interview, Wilder gave up two of his accomplices, Atkins said.
Owens was picked up at 2727 Godby Road, an apartment complex just blocks away from Butler’s and Winkler’s apartment, police said.
Traore was arrested in an apartment in the same complex where the women lived, but police declined to say whether he knew them.
The three arrested suspects were transferred overnight from the College Park Jail to the Fulton County Jail, police said. They are being held without bond.
Police continue to investigate the murders, and ask that anyone with information on the case call the College Park police tip lines at 404-768-8664 or 404-766-3131.
