Just weeks before he held a news conference on Wednesday announcing a $15 million lawsuit against Chicago police for excessive force, prosecutors said the Far South Side man at the center of the suit pulled out a gun after a dice game and fatally shot an unarmed man over $5.



The 22-year-old man killed in the May 27 Washington Park shooting had been sleeping on the floor during a game when Dominiq Greer began quarreling with the victim's cousin over money and pulled out the semi-automatic handgun with an extended clip, saying he should "kill the whole house," Cook County officials said Saturday at the Leighton Criminal Court Building in Chicago.



Greer, 25, of the 12400 block of South Eggleston Avenue, was arrested on a murder warrant Wednesday as he left his civil attorney's Loop office after completing his news conference. He was charged with first-degree murder in connection with the shooting death of Kevin Larry.



Larry apparently awoke during the argument inside the home in the 5600 block of South Wabash Avenue, held up his hands and told Greer, "I didn't do nothing," Assistant State's Attorney Erika Gilliam-Booker told Judge Peggy Chiampas.



After Greer made the threat, Larry's cousin left the home, leaving only Larry, Greer and a couple who lived at the home. The male resident told authorities he saw Greer with the gun and heard a gunshot when he went inside his bedroom and shut the door. The man's girlfriend told authorities she only heard the argument and the gunshot. The couple fled the home by jumping from a window, Gilliam-Booker said.



A sixth person was in the home just prior to the shooting but left because he lost his money in the dice game, prosecutors said.



Greer, who was dressed in a black blazer and dress pants similar to the clothing he wore the day he was arrested, stood in court with his left hand clutching his right arm behind his back.



"Do not say or mouth anything to me," Chiampas snapped at Greer after he apparently mumbled something as he stood before the judge.



"I didn't …" Greer said before the judge interrupted him.
