When killing yourself the right thing to do is to set it up some piano wire in such a way that you're able to sever your own head, AFTER supergluing your hands to the side of your head.

Its crucial that you have a friend that's in on it so that they can remove the piano wire when they "stumble" on to your dead body, and the investigators struggle to figure out how and why your ripped your own head off.
