John Mark Karr, who admitted to the murder of JonBenet Ramsey, has also confessed to his involvement in the string of infamous murders that terrified London in 1888. "The mystery can finally be solved - I am Jack the Ripper," said Karr. "And also the Boston Strangler." While Karr's former wife has presented an alibi that puts him outside Whitechapel in the late nineteenth century, the chief suspect is adamant, saying that he is not a publicity seeker. "The media should not treat this frivolously," he said. "After all, my assassination of Archduke Ferdinand started the First World War."
