Michael Taylor and his wife, Christine, lived in a small town in Great Britain called Ossett. The couple was very religious, and had joined a Christian prayer group lead by Marie Robinson. At one meeting in 1974, Christine Taylor accused her husband and Robinson of having an affair, which both people hotly denied. Michael Taylor then spewed obscenities and began acting extremely erratic and out of character, leading witnesses to think that he seemed possessed by evil.
After months of crazy behavior, Taylor eventually consulted with clergy who performed an exorcism. The exorcism lasted for well over twenty-four hours, and the priests involved claimed to have removed forty demons from the man’s body. However, before he left, the priests warned him that the demon of murder remained dormant in his soul.
As soon as Taylor arrived home, he brutally murdered his wife and their dog. He was later found wandering the streets, covered in blood. At his trial, he was acquitted by reason of insanity.
