Bruce Rivers has just posted a video talking about his son, Michael.

[EDIT]
According to Bruce in this video, Michael's death was an "overdose of a multiple cocktail of cocaine, methamphetamine and some derivative of Xanax", and he weighed 127lb (57kg) when he died.
Thoughts after watching:
I cannot imagine the horror Bruce went through finding his boy dead in the bathroom of an overdose.
The guy had some struggles growing up but seemed to be making good on the opportunities that came his way.
Bruce credits Michael with the success of the channel - when showing the silver and gold Play Buttons for the CLR Bruce Rivers channel, Bruce refers to it as "his work" and "his accomplishments" - which is such a fatherly thing to do.
