This is so tragic. I used to work with Roger and he's about as gifted of an engineer as I've ever met. He was so nice and helpful too, even though he was miles beyond me in terms of skill.

He was so into his indy game, Shard, and even whipped out his laptop to show me and started explaining intricacies of the renderer when I met him at an industry event years later.

I didn't know his wife, but from the things I've read she was also a pioneer in her industry. Rest in Peace.
