On NCIS Season 12 Episode 13, Virginia State Troper Vince Armstrong arrives home to find that his husband Lieutenant Eric Kutzler has been shot to death. Before calling 911, he hides some drugs that were found in their kitchen. As the DoD was vetting Lt. Kutzler for a Medal of Honor at the time of his death, Hollis Mann joins the NCIS team in the investigation into his death. Meanwhile, Tony, McGee and Bishop are troubled about Gibbs' state of mind - which probably has something to do with Diane's death. Tony pins his hope on Hollis Mann, who he refers to as "the Gibbs Whisperer". And in other news, Palmer is freaking out just a little bit as Breena comes closer to her due date for their baby. What's the reason for the lieutenant's murder? Was he killed because someone didn't like the fact that he's gay? What did the drugs have to do with it? Find out for yourself when you watch NCIS online.
