One of the theories surrounding the death of victim, Mary Kelly, was that she was not a Ripper victim. Since her face so badly injured that it could not be identified, people began to suspect that the victim was not Mary Kelly and that Mary Kelly, herself, killed another woman and stole her identity.
Part of this theory comes from the woman’s clothes in the fireplace-that Mary Kelly burned them to be rid of evidence.
Others believe the clothes were burning in he fireplace to give the Ripper light to work by, since he was indoors.
One of the questions that was never answered, in the death of Mary Kelly, was why the door to her room was closed and locked because the Ripper would not normally take time to do that.
Ripper suspect Montague John Druitt was said by an Inspector to be a doctor but research has found that he was in fact Assisant Master at Eliot Place school for boys. He was fired for “serious trouble” and disappeared at the time of Mary Kelly’s murder. Seven weeks later, his body was found in the Thames River with four large stones in his pockets.
“…She had on several occasions asked me to read about the murders. She seemed afraid of someone, but she did not express fear of any particular individual except when she rowed with me, but we always came to terms quickly.”
Statement made by Joseph Barnett at the inquest of Mary Kelly after her murder. He had a relationship with her and lived with her until a few days before she was murdered.
