In the next episode of "NCIS," Leroy Jethro Gibbs (Mark Harmon) revisits a case that happened a decade ago because of a new autopsy.

The trailer for the upcoming installment titled "Burden of Proof" was just released recently which showed a convicted felon telling investigators that he was framed by NCIS for a murder that happened 10 years ago. Gibbs and Jack Sloane (Maria Bello) look at each other in disbelief. New evidence has surfaced based on a recent autopsy by Donald "Ducky" Mallard (David McCallum) which prompts Gibbs to reopen the case which sentenced the felon to death row. "Resentencing an innocent man could kill a career," Sloane says to Gibbs. It appears he has to tread carefully so as not to make the wrong call during the investigation as a person's life is at stake.

It appears that an FBI agent may have influenced the past investigation. Gibbs tells Agent Fornell (Joe Spano), "You covered it up." It looks like Spano may have covered the tracks of the real killer and made it look like the convicted felon committed the murder. Spano tells Gibbs coldly, "Hypocrite does not look good on you." This suggests that Gibbs may have covered up something in the past as well. It remains to be seen what really happened 10 years ago and if the felon is really guilty of his crime.

In the previous episode, the team solved the murder of Petty Officer Jake Miller (Jordan Laesch) who was killed by a drug dealer. Agents Nick Torres (Wilmer Valderrama) and Ellie Bishop (Emily Wickersham) figured out the identity of the killer when they located the person who saw his face. The perpetrator was caught and interrogated.

"NCIS" season 15 episode 7 will hit the airwaves on Tuesday, Nov. 7 at 8 p.m. EDT on CBS.
