Officials continue to learn more about Kevin Downing, the New Jersey man who shot and killed a security guard in Manhattan on Friday before turning the gun on himself.

Sixty-eight-year-old Downing of Fort Lee, New Jersey, entered a building located at 201 Varick Street in Manhattan and shot a guard working in the screening area. He then walked through security and shot and killed himself.

The guard, identified as 53-year-old Idrissa Camara of Manhattan, was taken to a local hospital, where he was pronounced dead.

Downing, a former federal employee, was given what New Jersey Representative Bill Pascrell called a "raw deal" after losing his job at the Bureau of Labor Statistics. The congressman tried to help Downing and took his case after he was fired for allegedly being a whistleblower. 

Pascrell says the 68-year-old Downing suffered a string of misfortunes this year. His fiancee died of breast cancer, his house was in foreclosure and he had health problems after getting in a car accident.  

Camara worked as a protective officer for FJC Security Services. According to the firm, he was scheduled to complete his day at 4 p.m. but agreed to stay on for extra duty.

Witnesses say the scene was chaotic.

"We saw at least eight to ten cops running in front and so many, at least 50-60 people running towards us and the cop literally opened our door and said 'Get out of the car with your kids! There's a shooter!' And literally he pointed us towards the building, go in the building! We saw cops running, literally, and trying to save people," one witness said.

"Camara, who was armed, was an extraordinary Senior Guard who was well trained, cared deeply about his job and knew that building better than anyone else. It's clear from the facts that he never had a chance to defend himself in this instance," FJC said in a statement.

Camara was from the Ivory Coast. He is survived by his wife and four children.

"The main thing right now we think about him. He's not here anymore. We're praying for him right now," said Camara's cousin, Outtara Mohammad.

U.S. Secretary of Homeland Security Jeh Johnson went to SoHo Friday evening to speak to building employees. He also said he planned to express his condolences to Camara's family if given the opportunity.
