OKLAHOMA CITY (AP) — Surveillance video released by Oklahoma City police showed people rushing to help a Southwest Airlines employee after he was fatally shot while crossing a road outside the Will Rogers World Airport.

Police said Lloyd Dean Buie, 45, killed Michael Winchester, 52, on Nov. 15. Winchester's body is barely in the camera's frame when he is shot. He was pronounced dead at a local hospital.

Buie was later found dead in his pickup truck in the parking garage from which he shot Winchester, The Oklahoman (http://bit.ly/2hyeCYl ) reported. Oklahoma City Police Capt. Paco Balderrama said the second shot heard on the video is of Buie taking his own life with a handgun.

The video footage also showed Buie wandering around various areas of the airport for several hours on Nov. 11, eventually leaving his vehicle in the parking garage and departing in a taxi. Buie was then seen on the day of the shooting returning to his vehicle by another taxi.

Authorities said the shooting was likely in retaliation for Buie having lost his job with the airline last year. Buie used to work as a ramp agent under Winchester, but quit in April 2015 after being asked to take a drug test. Airline employees told authorities that Buie was known to have held a grudge against Winchester, but police cannot conclude for sure that the airline employee was Buie's intended target.

"We believe this is an obvious premeditated act," Balderrama said.

Winchester was a former University of Oklahoma football player and the father of current Kansas City Chiefs player James Winchester.
