Operations returning to normal at Will Rogers World Airport after deadly shooting

OKLAHOMA - Things at Will Rogers World Airport are returning to normal - as normal as they can be after a tragedy.

It was chaos at Will Rogers World Airport Tuesday afternoon.

Dozens of flights were canceled, and hundreds of people inside the terminal were urged to shelter in place.

"We walked out downstairs, and that’s when we started seeing all the police officers," said passenger DeAnn Martin.

Around 1, the massive manhunt for the shooter began.

52-year-old Michael Winchester, a Southwest Airlines employee, was shot and killed.

Authorities zeroed in on the parking garage.

"We do believe it was premeditated. We do believe the suspect had a firearm to obviously commit this murder," said Capt. Paco Balderrama.

Police found the suspect's pickup truck on the second floor of the garage.

The suspect was inside and died from a self-inflicted gunshot wound to the head.

"In most cases of homicides, the victim and suspect do know each other," Balderrama said.

Going forward, airport officials said they'll revisit security measures but said their current protocol worked.

"We do have active shooter training. We train for these situations," said spokesperson Karen Carney.

Questions surrounding a possible motive remain as a former Sooner standout's family grieves the loss of their loved one.

Police have not released the suspect's name but did search his home Tuesday night in southwest Oklahoma City.

Sources close to the investigation later possibly identified him as Lloyd Buie to NewsChannel 4, but officials have not confirmed it at this time.
