JACKSONVILLE, Fla. – A man already awaiting trial in a 2020 murder has been served an arrest warrant in a 2019 killing.
Hakeem Robinson, a 22-year-old rapper who goes by “Ksoo,” is charged in the February 2019 murder of 16-year-old Adrian Gainer Jr. at the Hilltop Village Apartments in Northwest Jacksonville, according to the warrant.
The warrant shows Gainer and another person were targeted by Robinson and another suspect who has not been charged.
When Gainer saw the two men coming, he started running but was gunned down in front of witnesses, according to the warrant. The other person escaped.
Police found 45 shell casings in the complex.
The warrant says Robinson later “posted several photographs and videos bragging about the murder.”
Last week, Robinson was served the arrest warrant in Gainer’s shooting death.
“I exhaled for the first time in two years. I could actually take a breath for the first time in two years,” said Elizabeth Gainer, the teen’s mother. “I’ll never give up. I’m going to keep fighting for my baby until I take and breathe my last breath.”
“I can finally get some sleep,” said Blanche Jordan, the teen’s grandmother.
“I need justice,” said Stephanie Fraizer, the teen’s godmother. “He’s behind bars, but guess what? We still need justice.”
Adrian Gainer’s nickname was Bibby, and his mother said Robinson named an album after her son called “Bibby Out.” She said his picture is on the cover with several other murder victims. She also said Robison also wrote about her son in his song.
“Every video took my breath away. It took my family breath’s away. My kids had to see that. My family had to see that,” Elizabeth Gainer said.
Adrian Gainer would have celebrated his 19th birthday on Friday.
Robinson has been in the Duval County jail since September. He is charged with murder in the January 2020 shooting death of rapper Charles McCormick. His father, Abdul Robinson Sr., is charged as an accessory in McCormick’s murder.
In a 2020 news conference last year JSO says the Robinsons are believed to be part of a violent drug trafficking organization called ATK -- also known as Ace’s Top Killers. The Sheriff’s Office has said the group consists of nine people, and that Abdul Robinson is the leader.
Hakeem Robinson’s brother, Abdul Robinson Jr., is also a murder suspect in that case and is being sought by the U.S. marshals, according to the Jacksonville Sheriff’s Office.
