A reader emailed us last night after arriving home at around 8 o’clock to find that her block of Warren Street between 3rd and 4th Avenues had been shut down following a shooting. There were a couple of dozen cops on hand, and they said that someone from the nearby Gowanus Houses had been shot; she inferred from there comments that it was a teenager. She also inferred that the shooter was still on the loose. Anyone else nearby pick up any other details?
