Dobyns became a Special Agent with the Bureau of Alcohol, Tobacco and Firearms (ATF) in 1987. Less than a week after beginning operational duty, he was taken hostage at gunpoint in the Tucson desert while serving an arrest warrant on a convicted felon who was recently released from prison. The suspect forced Dobyns into the driver seat of the officers’ undercover car, which was immediately surrounded by the other agents with guns drawn. During a brief standoff, the agitated gunman repeatedly screamed at Dobyns to drive away. When Dobyns intentionally pulled the car keys from the ignition and dropped them to the floor, the assailant fired a single .38 caliber pistol bullet into Dobyns’ lung, which exited his upper chest. The other ATF agents instantly opened fire from both sides of the car, killing the gunman. Critically wounded, Dobyns was rushed to a Tucson hospital, where Dr. Richard Carmona, who later became the 17th United States Surgeon General, performed emergency trauma surgery that saved Dobyns’ life.
