A concerned citizen witnessed the robbery happening from outside the store and waited there for the suspects.
The armed men took cash, cigarettes and lottery tickets before exiting the store. Outside they were confronted by the concerned citizen who told them not to move and that he was calling police.
Adams said a struggle ensued and the suspects took out their weapons. The citizen, however, was also armed and fired at the suspects.
The suspects were both shot in the chest and died at the scene.
Police took the armed citizen in for questioning, but after reviewing video of the incident and speaking with a number of witnesses, authorities released the man.
Adams said the shooter was very cooperative. The man had a license to carry, and since he was threatened at gunpoint, no charges are expected to be filed.
