On July 13, 2012 in Marion County, Florida two would be robbers came in and tried to rob the place. One had a gun and the other a baseball bat. You would assume their intention was to cause harm if necessary.
So a local patron with a concealed carry permit shot at them. It is confirmed that they were both shot because they were at the hospital treating gun shot wounds.
The video says the patron, Samuel Williams, is 63 years old while TheBlaze reports him as 71 years old.
