Wally finished his shift at 7:30 p.m. at the Colonial Theatre, got in his car, turned on his lights, and was then hurled 20 feet in the air through the roof of his car. The “dynamite” bomb was powerful enough to break windows in nearby buildings. Wally’s life was saved because the bomb was placed at the back of the driver’s seat and the backrest deflected the explosion. His heavy coat softened his fall.
