HOUSTON -- Police say a Houston jewelry store owner has shot and killed three men who tried to rob his business. Houston police spokesman Kese Smith says two men were in the store Thursday afternoon pretending to be customers when a third man burst into the store and stated, "This is a robbery." All three men then pulled out pistols, tied up the store owner's wife and took her to a back room. They were trying to tie up the owner, when he took a handgun from his waistband and fatally shot one of the suspects. He then grabbed a shotgun and shot and killed the other two suspects. The store owner was shot in the stomach and taken to a Houston hospital. Smith says his wife was not hurt.
