Shooting Rampage In Chicago

Three people are dead so far, including the gunman. Several others are hospitalized. There is not a lot of detail yet, the story is very new on the wires.

The shootings in the top floor of the 38-story Citigroup Center, which also houses a train station, sent office workers fleeing and stranded rush-hour commuters.

Authorities said earlier that three people were hospitalized in critical condition and one was in stable condition; besides the gunman, it was unclear who died.

The gunman, armed with a snub-nose revolver, knife and hammer, shot the four victims over "several minutes," police Superintendent Phil Cline said.

He was holding the hostage when police shot at him, but "before the offender died, he may have also shot himself," Cline said. Police said they won't know for sure until an autopsy is performed.

Cindy Penzick, secretary in a law firm on the 37th floor, said that after a co-worker told her she heard gunshots, a police officer with his gun drawn on their floor yelled at them to get out.

Penzick said she is usually calm, "But I have to tell you this was scary as hell."
