Police have identified the 53-year-old man fatally shot outside of a Tulsa Papa John's Pizza early Saturday morning.
Tulsa police say Robert Horton was a part of a two-man delivery team delivering supplies to the Papa John's Pizza near 11th Street and Delaware Avenue. Horton was outside the store when his co-worker inside heard a loud crash around 6:15 a.m.
The co-worker went outside and found him lying on the ground. Thinking Horton was suffering from a heart attack, the co-worker called 911 and reported a fall with injury.
Emergency crews arriving on the scene discovered Horton had been shot in the chest twice, police say.
Horton was transported to a local hospital where he was pronounced dead.
Both men are from the North Texas area, officials said. Horton was from Arlington, Texas.
Police say three suspects were seen leaving the area and are currently looking for a vehicle of interest.
