Investigation into the Death of Mossad Officer Michael Rivkin is an investigation that NCIS Special Agents Leroy Jethro Gibbs and Timothy McGee conducted in May 2009 in the aftermath of the fight between fellow NCIS Special Agent Anthony DiNozzo and Mossad Officer Michael Rivkin that later resulted in Rivkin's death. The investigation also ran alongside another one with both ultimately leading to the Journey To Israel.
