A serial killer is hunting human beings for the sexual thrill it gives him and will do it over and over again, believing he can outwit and outmaneuver the police, never expecting to be caught. The spree killer kills a number of victims at different locations in a short period of hours or days. But a mass killer is playing an endgame strategy.
Once he commits himself to his course of action, he does not expect to come out of it alive.
He will generally either kill himself after he's "made his statement" or commit what we call "suicide by cop"—forcing a confrontation in which the police or SWAT team will have no choice but to open fire.
I expect that later reports will say that this individual died at the scene.
These killers are such inadequate people, such losers, that they know they cannot get away and won't give others the satisfaction of controlling them or bringing them to justice.#1293•
