It was an illegal rooftop party of 30 to 40 people, mostly NYU undergrads, at 159 Second Avenue. The time was 1:30 am. One of the NYU students, who friends described as slightly intoxicated, decided to jump six steps, from the top floor landing down to the next landing.
Instead, that marble slab stairwell platform collapsed and pancaked. The young man crash-landed three stories below.
