Carmac was killed when the 2013 Mazda Miata he was driving crashed into a semi-truck and a Chevy Tahoe. He was 71 years old.
I personally knew him for over 8 years and am shocked by this news. He was famous here on reddit for his work with r/reportthespammers, and his classic list of the most over asked questions on reddit. And of course his awesome work here in r/geek, r/democrats and other liberal subreddits.
All of us here at reddit will miss him greatly.
Peace be with you my friend.
