A Florida man who recently got out of jail after being convicted of road rage was killed Wednesday after deputies said he got into a heated argument with a driver, who shot him.

Gary Lynn Durham, 40, was driving Wednesday morning in Plant City, when he stopped his truck and argued with the driver of a Ford SUV in front of him, the Tampa Bay Times reported. The argument between Durham and the other driver, Robert Padgett, 42, escalated to the point where Padgett pulled a handgun on Durham and shot him once, deputies said.

Padgett tried to perform CPR but was unable to save Durham, authorities said. Durham was dead when deputies arrived.

Durham was arrested in October 2001 after he got into a road-rage confrontation with Timothy James Gibbs. The two men went to a parking lot, where Durham delivered a punch in the face that knocked Gibbs to the concrete, where he hit his head, the Times reported. Gibbs died days later of a brain hemorrhage and skull fracture. Durham was convicted of manslaughter and served 10 years in prison.

"It's a shame that he didn't learn his lesson while in jail," Gibbs' widow, Nancy, told the Times. "I'm just glad I don't have to worry about him or running into him somewhere. It's ironic that he died in the same way as my husband."

No charges have been filed against Padgett as investigators determine whether Florida’s self-defense laws apply.
