The reason? The usual: ratings and money. The sources say that the ratings that each show gets just don't warrant a renewal for another season. But another source says that they might try to convince the stars and staff to take a pay cut so they can do another year. I can't say I would miss either of these shows. For a while there, Cold Case was a very effective drama, telling some rather interesting stories and using period music to get the emotion across. I never warmed to Without a Trace. It's not a bad show, it's just that I decided to watch cold case one night and the episode ended with them finding the body of the kid who was missing the whole episode. What a downer. So I didn't watch it again. so will you miss either of these shows?
