A couple sitting in their car at the shopping center was encountered by Christopher Rigby, 29, who asked them for some money. The couple refused to give him money and asked Rigby to "move on," police said.
"Approximately 15 to 20 minutes later, the couple observed the man again as he surprised them by approaching the driver's side of the car from the rear in an aggressive manner. He allegedly attacked the driver through the driver's window and attempted to stab him without provocation," police said in a news release.
The man in the car fought off Rigby with the knife and then grabbed a gun from the glove box, police said.
"He fired the weapon at his attacker who was hit and fell to the ground. He instructed his female companion to call 911 and stepped from the car to see the second man, who did not participate in the attack, flee on foot. The shooter remained on scene for responding Deputies," police said.
Police say another man, who was with Rigby before the attack, told them he witnessed Rigby attack the couple, because he was angry they did not give him money when he asked for it.
The man who shot Rigby has a license for a concealed weapon, police said.
No charges have been placed and this case is still under investigation, police said.
