100 years on, DNA casts doubt on Crippen case

It is one of the most notorious cases in British legal history, the story of an apparently mild-mannered doctor who poisoned and dismembered his showgirl wife, then fled across the Atlantic with his young lover - only to be caught after a sharp-eyed captain recognised him from the newspapers.

Dr Hawley Crippen was hanged in 1910, after an Old Bailey jury took just 27 minutes to find him guilty of murdering his wife, Cora, who had vanished earlier that year.
