The hail of gunfire broke out just before 1 p.m. Sunday at Mahoney Playground in New Brighton. Stuck in the crossfire was Stocco.
"I heard 'pow, pow, pow!' I thought it was like some fireworks or whatever. So when I bend down and look out the window, I see a lot of kids running," says Staten Island resident Tysnon Adams.
Police say the victim saw two people running before being hit in the left shoulder - as he was walking to a museum from the Staten Island Ferry. More than a half dozen shots were fired.
There were many kids in the park as violence was escalating, but they made it out just in time.
