There's water in central park. Would've been nothing to chuck the pistol in a pond. Break it down a bit if you're extra. Slide in one stream, barrel in another, mag, grip, etc until you've disposed of it. Or trash cans at various bus stops on the way down to VA. Tbf it's really easy to back seat something like this. His brain must've been running a mile a minute, it's honestly impressive how well he did
