Can playing cards help catch criminals?

Last month Mississippi Coast Crime Stoppers, a group that feeds anonymous tips from the public to the police, sent 2,500 decks of playing cards to inmates in seven county prisons and jails. Instead of jacks and queens, each card has the photo of a gulf-coaster who disappeared or was mysteriously killed. The group hopes that while prisoners pass time playing spades or gin rummy, they will come across a case they know something about and call in. The strategy reportedly worked elsewhere: authorities in Connecticut say that over the years decks like these have helped the state solve 20 cold cases; South Carolina claims at least eight and Florida two.
