A man is dead after being shot during an apparent road rage incident in San Antonio. The shooter told police another car cut him off as he was leaving a Walmart parking lot off Potranco. He then followed the motorist to a convenience store parking lot where he says he shot the man in self-defense after the other motorist pointed a gun at him first. The victim, 63, suffered multiple gunshot wounds and was airlifted to a hospital, where he died. The victim later died. Police are continuing to investigate.
