Warren, Minn.
Sounding groggy but calm, the Marshall County deputy sheriff radioed in from his patrol car at 2:19 a.m. on a lonely country road in northwest Minnesota.
"Something just hit my car," said Val Johnson. "I don't know how to explain it. Strange. … Something attacked my car."
He'd seen a bright light in the sky, he said, visible for miles across the flat prairie, and drove toward it to investigate.
Fellow officers listening in quickly got on the radio and began speculating about what had happened. Perhaps he'd been hit by a small car, one suggested.
Johnson cut them short.
"It wasn't a vehicle," he snapped. "I don't know what the hell it was."
Four decades later, nobody else knows what the hell it was, either. But that won't keep Warren from celebrating the biggest mystery to hit this town as far back as anyone can remember.
