The suspect walked into the building, pulled out a gun and shot the security guard, and then shot himself fatally." According to the Daily News "the fatally wounded security guard," who was employed by the federal government, died at Bellevue Hospital.

UPDATE, 7:05 p.m.: The NYPD has released this statement:

At approximately 5:05 PM a male walks into the federal building at 201 Varick Street. As he approached the metal detector in the security screening area, the male immediately pulled out a gun and shot the security guard at close range. He proceeded through the security area and headed towards the elevator where he encountered another employee. At this point, the suspect shot himself in the head. The suspect is dead on the scene. At this point we are working with a tentative identification and are working closely with the federal authorities, including DHS, FBI, and others to determine the suspect’s motive. At this time it appears there were no other suspects on the scene and the building is secure. We are at the very preliminary stages of this investigation based on what we know now. At this point there is no indication of a nexus to terrorism.

: The police identified the shooter as Kevin Downing, 68, saying, "Mr. Downing is a former federal employee and resided in Fort Lee, NJ. His residence has been secured while we await a court authorizedsearch warrant. We are at the very early stages of this investigation and are working to establish his motive for coming here, if he had an intended target beyond the security officer, and what the motive was behind this crime."

The guard was identified as Idrissa Camara, 53, who "never had a chance to defend himself." According to NY Times reporter Al Baker, Camara was "due to end work @ 4 PM, stayed for extra duty and got fatally shot, a spokesman for his employer said."
