Not sure if you know the history behind it, but look up Paul Le Roux
Also would recommend the book called The Mastermind by Evan Ratliff
imo Paul Le Roux has nothing to do with TrueCrypt
He wrote the code base that it is based on in combination with code he stole. The name is also based on an early name he chose for the software.
Whether he was involved in the organization and participated in it, is certainly up for debate, but it's not like he would admit it.
