This is one of two. As theories go conspiracy is pretty plausible in this case. Unless you’re just naive about how the world works.
But hey I guess they did some kind of mind control on him.
The coroner's report also sure sounds like a suicide. Gunshot to the right temple, very close range, from the victim's gun. No evidence of any struggle or forced entry. No evidence of anyone being with him. A note with only his fingerprints in what seems to be his handwriting.
Obviously there's no possibile way a mentally unstable person under a lot of continued stress would ever take their own life, just never happens. The only way people die are because corporations have them executed.
Is there even a single shred of evidence suggesting someone else pulled the trigger?
