Mercurial Chicago sportscaster Chet Coppock passed away in a car crash Wednesday night. 

His daughter left the following message on Facebook:

We lost our father, Chet Coppock, on April 17th due to complications from injuries he sustained in a car accident outside Hilton Head, SC. His passing is untimely, unexpected and painfully sad, but all we can do at this time is remember how lucky we were to have such a unique and creative trailblazer help shape into the adults we know he was so incredibly proud of.

Details on the crash are still being released.
