An unidentified man was shot and killed outside the offices of Colorado Gov. Bill Ritter.

(CNN) – Bodyguards for Colorado Gov. Bill Ritter shot and killed a man with a gun outside the governor's office in the state Capitol on Monday, but the governor was unhurt, his office said.

"The governor's fine," Ritter spokesman Evan Dreyer said. "Everybody is a bit rattled. Most of the staff has gone home. We'll be talking to them throughout the evening, but everybody is OK."

The shooting took place shortly after 2 p.m. (4 p.m. ET), outside Ritter's temporary suite of offices at the Capitol, which is currently being renovated. The man's identity was not immediately released, and his body lay in the hallway outside the governor's office as Colorado State Patrol officers wrapped yellow crime scene tape around the building's polished granite columns.

Senate Minority Leader Andy McElhany said there was "essentially no security" in the building after efforts to require visitors to pass through metal detectors "broke down."

"People who are in the building all the time, who were known to the Patrol, started going around the metal detectors, and other people would follow them," McElhany told CNN affiliate KUSA. "It got to be chaotic, and so they were removed. Probably some sort of higher level of security would be appropriate, but not going back to that level."

He said state police handled Monday's incident "very well."

"I think it's comforting for everyone in the building," he said.
