The Tell-Tale Cottonelle
-
A CSI team was investigating a murder scene, and they were at a dead end -- no DNA traces, all cleaned up -- when someone had a bright thought. The bathroom showed signs of a clean-up with little pieces of paper. And that led to the idea to run DNA tests on the toilet paper tube. And that's where they found DNA that led to a suspect and a conviction. Would you have thought of that? See, that's why you aren't doing forensic work. (WEWS-TV/Cleveland)
