On January 10, 1914, John G. Morrison and his son Arling were killed in their Salt Lake City grocery store by two armed intruders masked in red bandanas. The police first thought it was a crime of revenge, for nothing had been stolen and the elder Morrison had been a police officer, possibly creating many enemies. On the same evening, Joe Hill appeared on the doorstep of a local Doctor, with a bullet wound through the left lung. Hill said that he had been shot in an argument over a woman, whom he refused to name. The Doctor reported that Hill was armed with a pistol. Considering Morrison's past as a police officer, several men he had arrested were at first considered suspects; 12 people were arrested in the case before Hill was arrested and charged with the murder. A red bandana was found in Hill's room. The pistol purported to be in Hill's possession at the doctor's office was not found. Hill resolutely denied that he was involved in the robbery and killing of Morrison. He said that when he was shot, his hands were over his head, and the bullet hole in his coat — four inches below the exit wound in his back — seemed to support this claim. Hill did not testify at his trial, but his lawyers pointed out that four other people were treated for bullet wounds in Salt Lake City that same night, and that the lack of robbery and Hill's unfamiliarity with Morrison left him with no motive.
