JACK FEARS HE MAY HAVE CONTRIBUTED TO A PROFESSOR'S WRONGFUL MURDER CONVICTION SEVEN YEARS AGO WHEN NEW EVIDENCE SUGGESTS THAT THE IMPRISONED MAN'S VICTIM MAY BE ALIVE, ON "WITHOUT A TRACE," THURSDAY, OCT. 20

Emmy Award Nominee Justin Kirk ("Angels in America," "Weeds") Guest Stars as the Professor

"Lost Time"-- Jack fears that he may have elicited a wrongful murder confession during an intense interrogation seven years ago when new evidence suggests that the convicted professor's missing former student/lover may actually be alive, on WITHOUT A TRACE, Thursday, Oct. 20 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Martha Mitchell directed the episode written by David H. Goodman.

Emmy Award nominee Justin Kirk ("Angels in America," "Weeds") guest stars as the professor.

When the backpack and ID of a missing college co-ed are suddenly dropped off at a thrift store seven years after Jack, and ultimately the legal system, determined she was murdered by her married professor with whom she'd just ended an affair, the team decides to re-open the case. To their shock, the thrift store's grainy two-day-old security video shows a woman dropping off Skye's things who looks remarkably like Skye. As the team re-investigates this formerly high-profile case, Jack is especially eager to learn the truth, despite knowing that it may uncover a tragic mistake on his part that has already cost the professor seven years in prison.
