Ruins of homes in the 9400 block of South Massasoit Ave. in Oak Lawn in April 1967. In south suburban Oak Lawn, where 33 people died, the tornado rammed into the intersection of Southwest Highway and 95th Street at rush hour as motorists waited at a red light, flinging cars through the air. It destroyed a supermarket and badly damaged the high school. Eighteen died at that intersection alone. Then it roared up Southwest Highway, seemingly following the roadway before it ripped up a roller rink and destroyed 45 trailers at the Airway Trailer Park.
