I know a few guys who work at Perani's and heard about this around 1:30. According to this story he died on an international flight. I've met him a few times, great guy. The hockey world, as well as the Flint area, has lost a great individual. RIP Bob.

I never met him, but his original shop in Flint is one of the best hockey stores around. Very sad news.
