A black 16-year-old, who had acquired the chilling nickname 'Uzi', has been charged with the brutal killing of a gang rival

The black school girl, who is thought to have been named after the sub-machine gun, is charged with second degree murder after the Easter shooting of another teen. Nathaniel Walcott, also 16 and black, was gunned down while riding his child-sized bicycle in Brooklyn, New York City. Sahiah Davis, a newly inaugurated member of the Wave Gang, had been ordered to take down a member of her former crew, the Hood Starz, police sources said. Nathaniel, the son of a retired city correction officer, was shot in the lower back as he rode his bicycle near his home in Brooklyn. Police responding to a 911 call found the 16-year-old lying in a pool of blood near a playground park. He was rushed to hospital where he later died. Nathaniel had been visiting his parents in Brooklyn for Easter from a juvenile reform center in Westchester, in upstate New York. The troubled teen had spent the previous 18 months there, following disciplinary problems at school. A judge ordered that the 5-foot-11 schoolgirl be held without bail on murder and gun possession charges.
