Telegram sent by Scotland Yard in search for Dr Crippen and Ethel Le Neve, wanted for murder. The first use of wireless telegraphy in a criminal investigation was in July 1910. Crippen and Le Neve (disguised as a boy) fled to Canada on the SS Montrose but the ship's observant captain telegraphed his suspicions to Scotland Yard and the couple were arrested when they arrived in Quebec. Crippen was found guilty and hanged in London in November 1910. Ethel Le Neve was acquitted. She later married and had two children. She died in 1967.
