OKLAHOMA CITY - Oklahoma City police released the identity of the Southwest Airlines employee who was shot and killed Tuesday at Will Rogers World Airport.
The victim has been identified as 52-year-old Michael Winchester.
NewsChannel 4 learned that he was working at the airport on Tuesday when the shooting occurred.
Just before 1 p.m., officials say several people heard gunshots and alerted authorities.
Immediately after getting the call, Will Rogers World Airport was put on lock down.
No one was allowed in or out for four hours while police searched for an alleged suspect.
A portion of the search consisted of officers going to each vehicle in two parking garages and searching for the gunman.
Police say it is possible the shooting was tied to Winchester's job in some way.
However, they are not confirming if the suspect and Winchester knew one another.
On Tuesday evening, police began allowing people to leave after they had been checked out by officers.
The focus now is to formulate a plan to evacuate the airport and to get people off the planes that were grounded. They are going to use buses to get people out of the terminal, bringing them to N.W. 67 and Terminal Road so family members and friends can pick them up.
