Without a Trace (2002)

S3E9 Trials

When a juror goes missing, the first thought is that his vanishing is linked to the trial involving Terrell Brooks, who stands accused of killing Janelle Billingsley. As the team digs deeper, they uncover that Ducek recently altered his will to bequeath a large sum to his younger partner and has been quite secretive about a painting from his childhood in Czechoslovakia. This leads them to suspect that Ducek might actually be Klaus Reinhardt, a former Nazi soldier.
