UNIVERSITY CITY • A second man has been charged in connection with last week's slaying of a man on a University City street.

Kelly Winston Ervin II, of St. Louis, is accused of hiding the gun used to kill Curtis Robinson on Oct. 18. Ervin is not charged with the murder itself.

Authorities allege that Mario Richardson, 32, is the killer. Richardson was charged last week with murder, armed criminal action and unlawful possession of a gun.

Police say Richardson shot Robinson, 52, in the chest in the 6800 block of Raymond Avenue. Police didn’t give a motive but said there had been a fight. Witnesses saw the shooting and identified Richardson as the killer, according to court documents. He had earlier been seen pistol-whipping and threatening to kill Robinson, the records say.

Robinson was found on a sidewalk and pronounced dead at a hospital.

Police say Ervin removed the murder weapon, a semi-automatic handgun, from the crime scene. Ervin lives in the 4800 block of Penrose Avenue in St. Louis. He was charged Wednesday with tampering with physical evidence, a felony.
