A psych ward patient in Holland skated on an insanity plea after he killed power to an entire hospital thinking he was solving a puzzle in Silent Hill.
You might have heard of this, but a month ago or so, Jan H., the patient, shut down power to Sophia Hospital in the Netherlands thinking that by doing so he could acquire a toothbrush that would complete a puzzle. The hospital lost power for 45 minutes, stranding some folks in elevators and forcing doctors to resort to manual efforts to keep intensive care patients breathing. Noone was hurt. (Poor Noone.)
Turns out Jan H. skated on - what else - insanity. A court ruled he had "no idea of the true consequences of his deed."
