The high school dropout accused of fatally shooting four people outside a downtown bar insists he has never fired a gun in his life, despite past weapons charges, his lawyer said Thursday. Riccardo McCray, looking solemn and surrounded by guards, pleaded not guilty to four counts of second-degree murder, a day after he surrendered to authorities at a local television station; no bail was set. Relatives and friends had heard police were looking for him and asked a community activist to persuade him to turn himself in rather than run, said the activist, Darnell Jackson. McCray, 23, is accused of opening fire on a crowd outside the City Grill early Aug. 14. Some of the victims were part of a group attending a prelude to a wedding anniversary celebration. Four people were killed and four were wounded. Prosecutor James Bargnesi declined to provide a possible motive and said the case was headed to a grand jury. "We expect this to be a continually evolving investigation," he said outside the courtroom.
