The man holding the gun felt he had been cut off by the other driver, according to court documents.

MESA, Ariz. — A cellphone was rolling as a Valley driver was held at gunpoint in a case of road rage.

Court documents say Raymond Shepard, the man holding the gun, felt he had been cut off by another driver.

According to the documents, Shepard tailed the driver to a Lowes near US 60 and Ellsworth, where Shepard pointed a loaded Glock at the driver.

Travis Kelson and his wife had just stopped by the store to buy plants but instead stumbled on the intense standoff.

"He jumped out of his car immediately and pulled out a gun and started yelling at him, telling him to get on the ground and telling him he drives like crap," Kelson recalled.

The video shows Shepard cursing at the driver, while Kelson is heard asking Shepard to take his finger off the trigger.
