6. Joe Metheny
Having claimed three victims in his career as a serial killer, Joe Metheny signed a full confession where he discussed in detail how he killed the women. Once he had killed them, he butchered their bodies and stored them in the freezer. He then claims to have opened a beef stand, where he would sell roast and pork sandwiches. According to him, the sandwiches contained the meat of his victims, a fact of which the people purchasing the sandwiches were unaware, as according to Joe, human meat tastes like pork.
