According to the report, the customer -- a 57-year-old grandfather -- and two store employees were inside the Dollar General store Monday around 9 p.m. when two armed men entered the store with the intention to rob it.

"One of them had the clerk and one of them was at the front cash register,” Lt. Rob Schoonover of the Jacksonville Sheriff’s Office told Jacksonville.com.

The customer, who has a concealed weapon permit, shot and killed one of the intruders, FirstCoastNews.com reported.

"There was a citizen who had a concealed firearms permit that was inside the store as a customer," Lt. Schoonover told WOKV.com. "He fired at the suspect, striking him and killing him."

The man was found dead when police arrived at the scene. No charges are pending against the shooter, WOKV.com said.

“He’s always been a marksman,” the man's wife told Jacksonville.com. “He shoots in competitions, but this is the first time he’s ever killed anyone and I don’t know how he’ll handle that.”
