A man jumped to his death from the 66th floor of the Empire State Building yesterday afternoon. Police say that 21 year old Lower East Side resident David Ambramowitz purchased a ticket to go to the observation deck at the 86th floor, which he went to...but then went back down to the lobby and took an elevator to the 66th floor and apparently jumped out the window from a vacant office. Wait, isnt' the Empire State Building supposed to be pretty secure? With lobby attendants and guards watching people? Hmm. A worker on the 60th floor told the Daily News, "I saw this black shape out of the corner of my eye and thought nothing of it, like it was a bird." Abramowitz's body was found on a 6th floor ledge; his death may have been the 34th suicide at the building.
