I understand what you are getting at and it's making my head hurt
What about if you are running from a gunman and get shot--not detained but dead.
I'm trying to think of other scenerios. A poisoning maybe? If you are killed in your sleep? These just all sound ridiculous but I'm trying to think of murders that wouldn't involve, in the very least sense of the word kidnapping, a confinement or detaining someone/not allowing them to leave. Because if I think someone may cause me harm I am going to want to leave.
