"...Hmmm.... its like a scene from a conspiracy thriller:
Whisteblower takes his own life during a lawsuit against large corporation.
In the film, the initially presumed suicide would be revealed to have been staged & carried out the day before he was to give explosive new evidence about his erstwhile employer.
But this isn't a film its really life & no-one can imagine a large US firm employing people to rid them of a 'turbulent' witness, can they?..."
I knew a fellow who was, "suicided" by some folks he had betrayed. It happens but is very hard to prove.
