This is a concept, so I'll throw this out there.
John Doe was your average wageslave for Aztechnology. From as long as he can remember, he had been involved with the Aztechnology archology. His parents worked for them, he was born and raised an Aztechnology child. He even met his wife through the company. His wife was leading a special project for Aztechnology, one which would have put them in a monopoly position in the soy business. Aztechnology being what it is, they had a very tight leash on our hero's wife. When they heard the rumour that another of the Big Ten were preparing an extraction, they decided to take her away to an undisclosed location. However, when a team of runners tried to (unsuccesfully) hit that new location, Aztechnology knew they had a mole. They quickly tried to smoke it out, but to no avail.
With paranoia setting in, management was feeling a threat to their already dominant position, so they decided to destroy the special project in order to prevent others from obtaining it. They didn't leave any loose ends, taking care of John's wife as well and making it look like a suicide. John was distraught, but believed what Aztechnology told him.
It was not until a few months later that a team of runners, hired by Shiawase, gave an unaltered copy of the autopsy to John in the hopes of recruiting him. It clearly indicated there had been a struggle and a strangulation, not a hanging. But the worst part of the autopsy was that John's wife was pregnant.
This tipped John over the edge. He left Aztechnology then and there, but didn't throw himself in the arms of Shiawase; he instead vowed to try and do all he could to destabilize Aztechnology's position, wherever that might lead him.
