Scrutinizing a graphic murder scene: fun for the whole family! Turning tragedy into popcorn, this CBS-authorized whodunit turns you loose on one of three dioramas of slain corpses. You observe the details as closely as possible before taking your findings to a few touch-screen stations where you learn how investigators use forensics to find clues to crimes. Here’s a sample line from one video, which features actors from the shows: “Ah, the smell of decaying flesh… It’s an irresistible aroma to insects!” The satisfaction of solving the crime (it takes about 45 min.) may suit some visitors, although they may also have seen these facts addressed a hundred times in TV episodes. Still, the attraction’s cheap convention-chair seating, Xeroxed handouts, and unadorned facilities make it seem like it could pull up stakes and skip town in an hour.
