What nationality was the murderer Dr. Crippen?

Hawley Harvey Crippen (September 11, 1862 – November 23, 1910), usually known as Dr. Crippen, was an American homeopath, ear and eye specialist and medicine dispenser. He was hanged for the murder of his wife Cora Henrietta Crippen.

Crippen was put on trial at the Old Bailey before the Lord Chief Justice, Lord Alverstone on 18 October 1910. The proceedings would last four days. Throughout the proceedings and at his sentencing, Crippen showed no remorse for his wife only concern for his lover's reputation. The jury found Crippen guilty of murder after just 27 minutes of deliberations. Le Neve was charged only with being an accessory after the fact and acquitted.

Crippen was hanged by John Ellis at Pentonville Prison, London at 9am on Wednesday 23 November 1910.

In 2007, DNA evidence questioned the identification of the body found in Crippen's cellar that was supposed to be Crippen's wife. This evidence suggested that the remains discovered in his cellar were, in fact, those of a male person. These conclusions are disputed.
