Cops asked for the public’s help in tracking down three men linked to the murder of a Harlem gang member, officials and sources said. Raheem McWhite, 32, was walking along Lenox Ave. near W. 127th St. with a group of people, three or four abreast, at about 6:45 p.m. on Dec. 14. Suddenly, shots rang out, and McWhite clutched himself, then fell backwards to the ground outside of Yuzu Sushi on Lenox, sources said. He died at Harlem Hospital. McWhite, a Harlem resident who has 20 prior arrests on his record, survived a shooting in 2000, sources said.(nydailynews)…[+]
