I just heard a bulletin to that effect on the local news (there have been strange reports swirling around about his condition for weeks, so I won't link to any of those until something reliable to say develops). Apparently, though, he passed away after a severe bout of pneumonia ... and had been dealing with sarcoidosis for a long time, too, which complicated things. He was only 50. RIP.
