KANSAS CITY, Mo. -- A clerk at a 7-Eleven stood up to a robber, police said, and shot him dead.

An 18-year-old man was attempting to rob the convenience store near East 27th Street and Van Brunt Boulevard at gunpoint when one of the two clerks in the store pulled out his own gun and shot the man, police said.

When officers arrived at the store, which is across the street from a police station, they found the teen dead behind the counter, shot once in the neck.

"It is fairly unusual for us to have problems here, but convenience stores are one of those targets of opportunity, especially late at night. There were two clerks working at the time. One had on a uniform, one did not. The one that actually ended up doing the shooting was the one who was not in a uniform, but it is rather ironic to have something like this happen in such proximity to a police station," said Capt. Rich Lockhart of the Kansas City Police Department.

The man who was shot was carrying a gun, police said. And they said the clerk who had a gun had a permit to carry a concealed weapon.
