He was busted at a Tampa McDonald’s where he was employed after he walked in Tuesday and handed the manager a 9mm handgun. He asked his boss to hold on to it for him, employee Gail Rogers told the Tampa Bay Times.
While Donaldson walked away to apply for a payday loan at a nearby check-cashing store, Rogers said, the manager alerted a policewoman in the restaurant.
The cop called for backup and officers took Donaldson in for questioning when he returned. It was not revealed how he was linked to the killings.
