Comer shot at the guard with a 0.22-cal revolver, and the guard returned fire, killing him, police said. No charges were filed against the guard.
Hotel owner Ramesh Bhagat told Channel 2 Action News that the clerk handed over $150, but that it wasn't enough for the robber.
"He asked for more money, but we said ‘We don't have more money,' because we do all business by credit card," Bhagat told the news station.
The security guard noticed the commotion and intervened.
