On April 30, 1976 Evelyn Mooers attached a rappelling rope to a drain pipe grating on the roof of the Mark Twain South County Bank. Mooers, an experienced climber, had once scaled 14,410-foot Mt. Rainier in Washington state. The rappelling exercise from the bank building would have been routine but for one miscalculation. The drain pipe grating wasn't anchored.
Numerous bank officials and their friends watched as Mooers plummeted to her death. Her faith in the grating was fatally misplaced.
