He was later shot to death and left behind the abandoned home in the 1400 block of Grantling Street in Thomaston, Kilgore said.
Williams and Cameron Jones, her 20-year-old boyfriend, are in custody after being arrested in DeKalb County, according to Channel 2.
They are each charged with malice murder, felony murder, aggravated assault, kidnapping and possession of a firearm during the commission of certain crimes, according to the GBI.
Jones is being held at the Clayton County Jail and Williams is being held at the Upson County Jail.
Williams was also wanted in connection with a second homicide in Forest Park, police in that city announced Friday. Williams faces charges of armed robbery, aggravated assault and murder in the death of 28-year-old Mario Rashad Edwards of Covington.
Edwards was found dead inside a vacant apartment on College Street in the early morning hours of Dec. 21. He was shot at least once, Forest Park police said in a news release.
Williams did not act alone, according to police. Investigators have also identified Ashanti Dorsey, 21, as a suspect in Edwards’ death. Dorsey is sitting in the Clayton County jail on charges related to the Jan. 2 fatal shooting of another man, Dontavious Morrison, who police said was Dorsey’s boyfriend.
According to the Clayton County sheriff’s office, Dorsey is “a known prostitute and is a suspect in a series of robberies of men that solicited her services off of the internet.”
