I've never heard of this guy, but it's probably the same situation as with Edd Gould, which makes me sad. Because I was sad when Edd passed away, since I had been wrapped into animation because of him.
Sad to see people go like this. He probably had a bright animating future in front of him.
Edit:
What I don't understand though is how this guy can be someone's childhood? Most of his stuff is from YouTube and around 2012.
When I think childhood I think Newgrounds and 2005-2008.
