Richard Chase was a severely troubled young man and he had been that way his whole life. From arson to cruelty to animals, things started to escalate and just get worse. Much, much worse.
Richard Chase was a sick man. Really, really sick. He believed that his blood was poisoned and therefore killing him with toxic chemicals. The only solution was for Chase to drink blood—lots and lots of blood—from other sources so that his system was fully flushed out with a new transfusion.
Clean cut. While Richard Chase might look like a clean cut, handsome young man in this photo, he was extremely troubled, even at a young age. He committed arson and was extremely cruel to animals.
Abusive childhood. Chase's parents were very abusive. Richard's father administered brutal beatings regularly. It was at this point that Richard started drinking.
Hospitalization. Chase was briefly hospitalized with a blood infection. He contracted the infection after killing a rabbit and drinking its blood. After his stay at the hospital, he was taken to a mental health facility for a while.
