OKLAHOMA CITY, Okla. (WTXF/AP) - Police say the man accused of shooting an Oklahoma City airport employee to death used to work for Southwest Airlines and the motive was likely retaliation.
They identified the gunman as Lloyd Dean Buie, of Oklahoma City. Shortly after Tuesday afternoon's shooting, he was found dead from a self-inflicted gunshot wound in a red pickup truck on a parking garage roof.
Buie resigned from his job in April 2015.
Investigators believe he shot and killed 52-year-old Michael Winchester in retaliation for the circumstances that led to Buie leaving the job.
But police say they don't know what Buie did for Southwest or why he resigned. Winchester was not Buie's immediate supervisor.
Also Wednesday, flights at Will Rogers World Airport were operating normally again. Air traffic control had implemented a ground stop after the 1pm shooting. It was lifted at about 6pm. The incident caused 25 flights to be canceled.
Fifteen of those flights were operated by Southwest Airlines. The company's CEO, Gary Kelly, said on Twitter the airline "will do everything we can to support Mike's family."
