A teenager was shot and killed in Upper Manhattan Monday night, cops said.

Police responded to reports of gunfire near Alexander Hamilton Playground on West 140th Street just before 10 p.m. and found Manauris Davis, 19, lying unconscious on the sidewalk with a gunshot wound to the torso.

Manauris, who lives two blocks away, was rushed to St. Luke’s Hospital, but pronounced dead on arrival.

The prime suspect in the shooting, a man in his mid ’20s wearing a white shirt, fled east and remains at large, authorities said.
