OKLAHOMA CITY - A disgruntled co-worker is named in the deadly shooting at Will Rogers World Airport.

Oklahoma City Police confirm Lloyd Buie, 45, shot a Southwest Airlines supervisor then turned the gun on himself on Tuesday.

"We know his intentions were to go to the airport and hurt someone and he did," said captain Paco Balderrama.

On behalf of the Oklahoma City Police Department, Balderrama said the investigation has revealed the killing was premeditated.

Police say the motive has not yet been determined, however, new documents show Lloyd Buie was jobless and buried in hundreds of thousands of dollars in debt.

A Chapter 7 Bankruptcy filing shows his money woes began in April 2015 when he refused to take an on-the-job alcohol test.

In response to a News 9 inquiry, Southwest Airlines released the following statement:

"Regarding your question on Mr. Buie’s departure from the Company, there is limited information we can share. While working in Oklahoma City, also as a Ramp Agent, he was exhibiting signs and symptoms of being under the influence of alcohol while at work one day in April 2015. Southwest immediately requested that he be tested; he declined and resigned." - Michelle Agnew, Southwest Airlines Media Relations.

Police said Buie may have been retaliating for the circumstances that led to him resigning.

Balderrama said the victim, Michael Winchester, a longtime Southwest Airlines employee, was not Buie's immediate supervisor.

Buie remained without a job up to his suicide.

According to financial records, he racked up $97,203 in credit card debt. He filed bankruptcy in September and reported $254,761 in liabilities including his mortgage and auto loan.

Army officials say he served from 1992 to 1999, including a tour overseas during the Bosnian conflict in 1994. He was awarded several medals, including the Army Achievement medal given to soldiers with outstanding service.

Police also searched his home in Southwest Oklahoma City. Several items, including guns, were reportedly removed from the home. An inventory from the search has not yet been filed at the Oklahoma County Courthouse.
