In 1963, Peter Reyn-Bardt killed his wife and buried her in a peat bog in Cheshire County, England. Twenty years later, when a body was discovered, he assumed he’d been caught and turned himself in.

He should have waited. An investigation showed that the body was not his wife’s, but that of an Iron Age man who had died two thousand years earlier and been eerily preserved in the cold acid bog.

They convicted Reyn-Bardt anyway.
