What happened in NCIS: Origins episode 17

NCIS: Origins Episode 17, titled, Darlin', Don't Refrain, followed up on the Sandman case after the murder of Jamison Boyd, who was sniped in his prison. It was revealed earlier that the real killer was still out in the open and was related to Operation Sundown. However, the NIS team had no idea what it was, as the file sent by the FBI containing the information was shredded.

Most of the episode was about the agents working with the FBI to gather more intel. The relationship between Wheeler and his son was also explored in the episode.

Eventually, Gibbs found a clue from Vera's interrogation tapes and realized that the real Sandman was Luke Fletcher from his Veterans' Support Group. He confronted him at his house, which turned into a battleground, resulting in Gibbs stabbing Fletcher to death.

Here's the official synopsis of the episode:

"Vera receives an unexpected call from Bugs, who claims he’s ready to answer more questions from prison after being identified as the sniper known as 'Sandman.' When she arrives, Bugs has suddenly changed his mind, prompting the team to reconsider the case and race against the clock to try and stop another tragedy.”
