The man was not a traveler but apparently entered the terminal near Door 2 to use a restroom, authorities said. The MetroLink platform is close to what would be Door 1. The restrooms are closer to Door 2. The shooting was on the upper level of the terminal. The TSA security checkpoints are on the lower level. "This was not a passenger or anyone using the airport for travel," Vera Clay, a St. Louis County police spokeswoman, said in an interview. Two airport police officers initially confronted the man, who brandished the knife when told to drop it, as if to say, "I'm not leaving," Clay said. One officer used a Taser, but the man kept coming toward them. The second officer then shot him. Airport police asked that St. Louis County detectives investigate the shooting. They did not identify the airport officers, other than to say one is 39 years old and has 12 years' experience in law enforcement; the other is 43 with two years' experience. Police said he lived at an apartment complex in Peoria, Illinois.
