Arne Cheyenne Johnson is known for being involved in a notable legal case in the early 1980s. He gained public attention after being charged with the murder of his landlord, Alan Bono, in 1981. The case became famous due to its connection to the Warrens, paranormal investigators who claimed that Johnson was influenced by demonic possession. The trial was significant as it was one of the first instances in the United States where a defendant attempted to use demonic possession as a legal defense. Although the defense was ultimately unsuccessful, the case sparked widespread media coverage and discussions about the intersection of law and the supernatural, particularly in relation to the occult.
