The cast member whose character was killed on this week's episode of "Person of Interest" is to appear on "Late Show with David Letterman" in New York. CBS said Taraji P. Henson will talk about her New York Police Department Detective Joss Carter's "shocking exit" from the crime drama series when she visits "Late Show" Wednesday. "This will be Henson's first television interview since her character's surprising demise on Tuesday night's episode of the series," the network said in a news release. Now in its third season, the show co-stars Jim Caviezel, Michael Emerson and Robert John Burke.
