Without a Trace (2002)

Season 3: Episode 9

When a juror disappears, the initial belief is that his disappearance is connected to the trial that is being covered, where a young man named Terrell Brooks has accused of murdering Janelle Billingsley. When the team investigates further, they learn that not only did Ducek change his will to leave his younger lover a fortune, but he has been rather mysterious about a painting from his youth in Czechoslovakia. The team soon begins to believe that Ducek is really a former Nazi soldier named Klaus Reinhardt.
