The agents found out it was actually Ray who was behind the killing of a Navy lieutenant. He had made several mistakes on his work trip as he missed his target in Pakistan, tracked him back

to America and illegally attempted to kill the target on US soil. When he missed, he accidentally murdered the Navy lieutenant and tried to cover it up. NCIS took Ray away but before they

did, Ziva punched her now ex-boyfriend in the jaw. _NCIS IS AVAILABLE TO WATCH ON CBS._
