In 1975, Chase was involuntarily committed to a mental institution after being taken to a hospital for blood poisoning, which he contracted after injecting rabbit’s blood into his veins.
Chase escaped from the hospital and went home to his mother; he was apprehended and sent to an institution for the criminally insane, where he often shared with the staff fantasies about killing rabbits. He was once found with blood smeared around his mouth; hospital staff discovered that he had captured two birds through the bars on his bedroom windows, snapped their necks, and sucked their blood out. Among themselves, the staff began referring to him as “Dracula.”
After undergoing a battery of treatments involving psychotropic drugs, Chase was deemed no longer a danger to society, and in 1976, he was released into the recognizance of his parents; his mother, deciding that her son did not need to be on the antischizophrenic medication that he had been prescribed, weaned him off it.
