In life, German knight Christian Friedrich von Kahlbutz, felt he was entitled to any woman (virgin or wife) he wanted. When the wife of a shepherd refused him, he took his revenge on the woman's husband and murdered him. At his trial he swore an oath, "It was not I, otherwise after my death my body will not decay". Oddly, that is exactly what DID happen. Some say that the preserved state of his body is proof of his guilt while others say that it is simply a case of natural mummification.
