The 14-year-old Jersey City boy who was found with a gunshot wound Tuesday afternoon near his grammar school shot himself, police said this morning.

The School 15 student has been charged with unlawful possession of a handgun, possession of a weapon for unlawful purposes and possession of a firearm by a minor, city spokeswoman Jennifer Morrill said.

Initially it was reported that the boy was shot in the calf sometime around 3:30 p.m., near the corner of Wegman Parkway and Van Cleef Street. He went back to the school, about a block away, and police were called.

But police began doubting the boy's initial statements after they viewed surveillance video, Morrill said yesterday. It was not immediately known if the boy had the gun inside the school during the school day.

The 14-year-old was treated and released from the Jersey City Medical Center-RWJBarnabas and then remanded to a juvenile detention center in Union County.
