Nah
he shot himself in the back of the head 3 times and then threw the gun away and lay down and died...

I would be commenting "LOL!" but homicide is a very serious matter. And this was almost surely a homicide conspiracy.
Once you come to that conclusion, it would follow that the Clintons, at a minimum, gave the murder plot their blessing. If that were not the case, you can bet the farm that there would have been arrests and criminal charges against a perp or perps (much more likely plural) within a short time frame after the death.
Instead, there occurred a multi-faceted government cover-up rather than an objective government investigation.
Unfortunately, the Foster homicide case has for 24 years been the taboo of all taboos as far as the unwillingness for government to disclose the truth is concerned.
