Story highlights Police say man attacked one airport officer with knife

Suspect tried to buy ticket with woman's ID, then went back to car parked outside terminal

Two confrontations with officers end with man dead

(CNN) An Ohio man with a knife was shot and killed Wednesday after lunging at one airport police officer and acting in a threatening manner toward another officer, a Columbus police sergeant said.

Sgt. Rich Weiner said the man tried to buy a ticket with a woman's identification at Port Columbus International Airport, then with his own ID, but was refused. The man, who was in his early 40s and lived in the Columbus area, returned to his car, where one officer was investigating a suspicious vehicle call.

The man and the officer were talking, police said, when the suspect pulled a knife and tried to attack the officer, who opened fire. It is unclear whether the man was struck by any of the shots from the officer, but he fell, then stood up.

As he made his way toward the terminal, backup officers approached. The man, who still had a knife in his hand, was shot by one of those officers.

Weiner only said that multiple shots were fired. He didn't disclose how many times the man was struck.
