Portrait of a Killer - Jack the Ripper - Case Closed (Abridged, Downloadable audio file, Abridged, Windows Media ed)

Using the first-hand expertise she has gained through writing the bestselling Dr Kay Scarpetta novels, Patricia Cornwell has used the demanding methods of modern forensic investigation to re-examine the contemporaneous evidence in the Jack the Ripper murders. These include state-of-the-art DNA testing on various materials, computer enhancement of watermarks and expert examinations of hand-writing, paper, inks and other relics. She has also used her knowledge of profiling on the possible suspects, as well as consulting experts in the field. On presenting her conclusions to a very senior Metropolitan Police Officer, she learned that had the investigators of the time been presented with the facts she has unearthed her suspect would definitely have been arrested and would probably have faced trial. He was the artist Walter Sickert.
