Serial Killers Caught by the Dumbest Clue

Some of them killed for decades without a single suspect. Some lived quiet lives right next door. And every one of them was caught by something completely ordinary. A receipt. A sales slip. A pizza crust. A coworker in a pub. A traffic stop. A missing license plate. False number plates. A few miles over the speed limit. In this case file we break down 8 real serial killer cases and the one ordinary clue that finally closed each of them. No graphic content, just how investigators caught them. Which case should we open next?
