Twenty years ago, on Dec. 11, 1990, Dyer was the first responder to the worst fatal accident on Tennessee highways in nearly two decades, and the most deadly fog-induced wreck in state history, according to the Tennessee Highway Patrol.
Ultimately 12 people died and 42 were injured in the 99-vehicle pileup, which began on the southbound highway when one tractor-trailer rear-ended another in the dense fog.
