(CNN) -- A man dressed in black walked into the lobby of a federal courthouse in Las Vegas, Nevada, pulled a shotgun from underneath his jacket and opened fire Monday, killing a court security officer and injuring a deputy U.S. marshal, an FBI spokesman said.
Seven marshals and security officers returned fire as they pursued the man into the street, FBI spokesman Joseph Dickey said. One witness described the volley of gunshots as "surreal," and another, who captured the firefight on video, said it was "unbelievable."
The suspect was shot by marshals and killed.
The deputy marshal and the security officer were taken to a hospital, where the security officer, Stanley W. Cooper, died, said U.S. Marshals spokesman Jeff Carter.
