Poisoned Waffles
The most puzzling aspect of that story to me has always been the fact that when you commit a crime, and somebody kill your accomplice you are under penalty of first degree murder. A quirk of the US system as far as I can tell.
It's not just a US thing. It's present in many legal systems, including the UK's. There was a famous case involving it back in the death penalty days, but I forget the name of it. I think he got the death penalty because he was one of several people committing a robbery and one of his partners shot and killed a cop. Anybody remember that one?
