i read this story more fully few weeks ago, can't remember where, the guy was long term unemployed, suffered from depression and was facing homelessness
it was all very tragic, there was nothing to point to foul play, he'ld rigged up the chainsaw at the end of his table, taking a huge dose of sleeping pills, laid on the table and when he couldn't stay awake any longer his head fell onto the blade
a somewhat ingenious, if macabre, why of dispatching oneself and sending a message to unsympathetic housing developers
