Two separate car crashes happened near the same exit on the Edens Expy. early Thursday. And in south suburban Harvey, an elderly man was killed when his car struck a building. First, police said an Evanston man sparked a three-car crash by driving in the wrong direction on the Edens, just south of Peterson Avenue. About 1½ hours later, police said, a man apparently fell asleep behind the wheel and smashed into a state trooper's vehicle, also close to the Peterson exit.
