David Runion was a man who was also later revealed to be responsible for the death of Sergeant William Moore despite Runion himself insisting that he was innocent.
Fortunately, Abigail Sciuto and Timothy McGee uncovered proof that he had the one to kill Sergeant Moore, resulting in Leroy Jethro Gibbs, Anthony DiNozzo and Caitlin Todd attempting to arrest him for the crime but Runion spotted them first and quickly assembling a gun, began shooting at them while vowing not to go back to prison.
Luckily, though, Gibbs had a plan which first involved getting Runion's dog to safety via Gibbs whistling and after telling Kate and Tony to cover their ears, Gibbs shot the propane tank attached to the trailer, causing it to blow up and presumably killing Runion who was inside at the time.
Kate later adopted Runion's dog, calling the dog who was actually a girl "Toni".
