[Villages PL]

I haven't heard this reason being advanced anywhere and would like to try it out here to see what you think.

Everyone always says that the shooter shoots himself at the end because he doesn't want to be captured by the police. I think that's true but only part of the truth.

I think the main motivation from the very beginning is suicide and the shooter wants to create a situation conducive to that end.

His plan is to not die alone; his plan is to take others with him. At the end, as the police are arriving, he only has a small window of opportunity to complete his plan. He doesn't have much time to think and the pressure is just what he needs to take that final step to do what he has been wanting to do all along. And that is to take his own life.
