1. Karl Denke

Karl Denke was a German man who was apprehended by police in 1924 for a series of horrific murders. Surprisingly, Denke was actually known around his town of Wroclaw as being an incredibly philanthropic man. He regularly helped beggars and homeless people, and was so well respected that his nickname was “Papa Denke.” One day, screams were heard from Denke’s property and a man was found bleeding profusely from his head nearby. The man claimed that ‘Papa’ had attacked him with an ax.

After much disbelief, police followed up by searching Denke’s property where they made a grisly discovery.

A log with the information of roughly 42 victims who Denke murdered and cannibalized was found on the property. Other reports indicate that he pickled human body parts and sold it to townspeople as pork.

2. Joe Metheny

This horrific individual wasn’t known for the number of people he killed, but more for what he did with his victims after murdering them. Metheny particularly targeted prostitutes for his killings, claiming to have murdered eight people dating back to 1976. In court, Metheny said, “I cut the meat up and put it in some Tupperware bowls then put it in a freezer.”

What he admitted to next is beyond comprehension.

“I opened up a little open-pit beef stand. I had real roast beef and pork sandwiches. They were very good,” he said. Metheny added, “The human body taste was very similar to pork. If you mix it together no one can tell the difference.”
