PHOENIX -- An office building in Phoenix was full of people when someone started firing a gun in the lobby Wednesday morning.
"We heard loud noises. I didn't know it was gunshots at the time," said Karen Greenhow, who works in the building. "Then we had someone come into our office and say there was a gunman with two handguns and that there had been a shooting," explained Greenhow.
Greenhow's office is on the second floor of the building.
