Tullier was drinking coffee with a fellow deputy, Sgt. Bruce Simmons, the morning of July 17, 2016, when a call crackled over the radio: Shots fired, officer down. The two deputies raced to the B-Quik convenience store on Airline Highway, where a lone gunman was shooting police and deputies.
Tullier spotted the gunman's car, a rented Chevy Malibu with Missouri tags, and was running the plates when the gunman opened fire on him with a rifle. One round struck Tullier in the stomach and a second hit him in the head, shattering his skull and damaging his brain. A third bullet struck Tullier in the shoulder.
Three other officers died in the attack: Deputy Brad Garafola and Baton Rouge policemen Montrell Jackson and Matthew Gerald.
The gunman was killed by law enforcement.
Tullier worked as a patrol deputy with the East Baton Rouge Parish Sheriff's Office for nearly two decades.
