How was dr.crippen caught?

Dr. Hawley Crippen was caught after a suspicious neighbor alerted authorities about the unusual behavior in his home, particularly the disappearance of his wife, Cora. When police investigated, they found evidence that led them to believe a crime had occurred, including traces of human remains in the basement. Crippen attempted to flee to Canada with his mistress, Ethel Le Neve, but was apprehended on a transatlantic ship after the ship's wireless operator recognized him from a police bulletin. His capture marked one of the first uses of wireless communication in a police pursuit.
