Not wanting people to know you've killed yourself?

I also submit that if you sort of don't care how big of an imposition your suicide be to random passers by, the police, emergency response, etc... then your plan is irrational or mean-spirited or both.

I still say there's easier ways, this was VERY planned and it seems most of the planning is surrounding the covering of his identity.

Well, he obviously didn't do that good a job erasing himself; there's a whole documentary about him now.

Point Homer.
