James Tremaine Green, 32, died on Feb. 8, 2014, after two shotgun blasts to the stomach at his home. Suspects had fled the scene when police arrived, and Williams was not arrested at the time.
Williams and two other alleged Bloods were indicted this September with murder, burglary and other charges in that case.
Police haven't released a motive. Holland said it was a robbery.
Afterward, people told Holland's family Williams wouldn't be found because he had likely fled to Florida.
According to DeKalb police, he was on Glenwood Road this August when Keaira Palmer died. She was walking out of S and N Lotto with a group of people.
Keaira Palmer, 15, was shot to death Aug. 3 while walking out of a convenience store on Glenwood Road.
According to the FBI, the shooting stemmed from a previous incident in which Williams was robbed by members of a rival gang set. Williams allegedly holds the rank of Double OG in the Six Deuce Brim Bloods.
He and five others face charges in the DeKalb shooting. According to his arrest warrant, he used his rank and "ordered" the shooting of G-Shine Bloods before Palmer was shot in the crowd.
Williams was arrested last month after several months wanted.
Holland was disturbed to hear of Palmer's shooting.
"When I saw he was wanted for killing that girl, I knew right then he didn’t care,” she said. “I am so happy that he’s arrested.
"We know we’ll get justice now.”
