On the afternoon of June 26, 1977, a 16-year-old runaway named Andrew Zimmer, held in a padded isolation cell at the Maury County Jail just off the courthouse square, set fire to his cell's padding with a borrowed match. The padding was polyurethane, and the smoke it produced carried cyanide gas through the building's air ducts within minutes. The jail had no sprinklers and no automatic locks — every cell had to be opened individually, by hand, and in the panic the keys were lost.
Forty-two people died: 33 inmates and, because it was visiting day and visitors were customarily locked in alongside the inmates they came to see, nine family members who had simply come to visit. The Herman family lost six members that afternoon. The Golden family, there to see their son, lost five. It remains the deadliest jail fire in Tennessee history and one of the worst in the nation.
The disaster became a turning point for jail safety nationwide. In its wake, Tennessee and other states moved to strip polyurethane mattresses and padding from cells, install sprinkler systems, and adopt centralized locking so a jail could never again be unlocked only one key at a time while smoke filled the halls. Columbia carries that history on the same ground where it happened — this Friday, on the fire's 49th anniversary, the city dedicates a historical marker there naming what was lost.
