Donaldson had handed a coworker a McDonald's bag with a loaded .40 caliber Glock pistol inside of it and told the coworker he planned to leave the state, Dugan said. The coworker approached a police officer who was at the restaurant.
Donaldson returned a short while later and was detained by the police officer, Dugan said.
Police said Donaldson gave officers permission to search his vehicle and his cellphone and to examine his gun, which he legally purchased Oct. 3. He was taken to police headquarters for questioning.
Four people have been shot and killed in the Seminole Heights neighborhood since Oct. 9, but detectives had not determined Donaldson's connection to the area, nor have they established a motive, Dugan said.
