2. Daniel and Manuela Ruda
In the year 2001, this German couple murdered Daniel’s co-worker and friend, stabbing him 66 times, hitting him with a hammer and drinking his blood. Afterwards, they had sex in Manuela’s coffin. They claim to have acted on the devil’s orders and said they chose their victim (named Frank Hackert, age 33) because he was “so funny and would be the perfect court jester for Satan” During their trial, they acted completely without remorse, threatening witnesses and flashing satanic symbols. Daniel Ruda was committed for 15 years and his wife for 13.
