It is very rare for a convenience clerk to be this out in front of an armed robbery crew, who tend to rely on surprise and overwhelming violence to succeed. When they lost the element of surprise and a determined clerk met them with aimed fire in the confines of the doorway, it was a slaughter.

Thompson appears to be the third robber who escaped from the scene, and his involvement in the robbery got him two murder charges for the deaths of his fellow robbers under the felony murder rule. It isn’t precisely clear if Williamson had any direct role in this robbery, but he was apparently tied to other crimes committed by Thompson and his two partners who have decided to participate in the Room Temperature Challenge.

Authorities have evidence tying the robbery crew to at least eight other robberies.

The case will likely be reviewed by the Tulsa County District Attorney’s Office, who may have a few additional questions for the clerk on duty, regarding his situational awareness, his training, and what hours he might be available for consulting as a combat marksmanship instructor to local law enforcement.
