"By all accounts, Len was on track to be one of the most important cryptographers of his time. But on July 3rd, 2011, he tragically took his own life at 31, following a long battle with depression and functional neurological disorders.
His death coincided with the disappearance of the world’s most famous cypherpunk: Satoshi Nakamoto. Only 2 months before Len died, Satoshi sent their final communication:
I’ve moved on to other things and probably won’t be around in the future." [0]

I very strongly disagree, as would many others. I also think there are good arguments against the Sassaman theory.
