R -v- John Humble

‘The Yorkshire Ripper Hoaxer’ trial |

J P French Associates analysed the voice and speech patterns in a police interview recording made 26 years after the original hoax tapes received by the police.  The recordings were authenticated and speaker comparison provided evidence that lead to John Samuel Humble admitting that he was in fact the hoaxer.  The analysis was so extraordinary, given the length of delay, that the findings were published in a scientific journal article.

Leeds Crown Court, March 2006.
