Suicides - or drug overdoses - especially of celebrities or powerful people like this guy - should always be carefullly investigated as I believe a good percentage of them are murders. Maybe most of them are murders.

So many reasons to kill a lot of folks - one thing people never consider about celebrities is how heavily INSURED many of them are and a if they are at the end of their careers, ala Robin Williams, they may well be worth more dead than alive.

The default in any of these deaths should be homicide.
