The Santa Fe New Mexican reports (http://bit.ly/V4b4qD) that the 33-year-old driver of the truck had slammed into his vehicle Sunday and was confronted by the car's 67-year-old owner who heard the crash and went out to investigate.
The identities of both men haven't yet been released.
Police say the truck's driver approached the older man after the crash and sliced his face with a knife.
The car owner pulled out a handgun he was carrying and fired a single shot into the truck driver's abdomen.
The truck driver remained hospitalized after the bullet punctured his liver, lung, and one of his vertebrae.
