That's precisely what happened last Wednesday when a man was hailed as a "good Samaritan" by police after he stopped an active shooter at an Amazon Flex Warehouse in Chandler, Arizona, according to FOX 10 Phoenix. 

Bryton Bobbitt, a contracted Amazon worker, told reporters he was preparing for his delivery route when he heard gunfire: 

"All of a sudden, just hear pop, pop, pop. [I] start looking around, like where did that come from? A few of our other workers started running.

"I was already in my work van, I put it in gear and tried to find a safe place and got out of here."

Meanwhile, a second Amazon worker, who was armed, saw the shooter, 29-year-old Jacob Murphy, attempt to enter the building before shooting an employee. The shooter was a non-employee searching for a person at the facility over "jealousy issues" regarding his girlfriend. 

That's when the armed Amazon worker went into action and fired at Murphy, wounding him. The shooter instantly dropped to the ground, likely preventing further bloodshed. Then the armed Amazon worker rushed over to the individual who the suspect shot until first responders arrived on the scene.
