A COLD case investigation into Jack the Ripper is explained by retired murder squad detective and leading expert Trevor Marriott at Harpenden Public Halls tomorrow night (Friday).

The Jack the Ripper murders are still unsolved and Trevor has been working on a cold case investigation into the Whitechapel Murders of 1888 since 2002.

He has now concluded his long and protracted cold case investigation with results which now have completely dispelled many of the original theories which have been readily accepted as being fact for 125 years.

His one-man show is packed with pictures from 1888 showing original crime scene photographs of the victims, the suspects and many other original photographs from 1888 relative to the murders.

The evening begins at 7.30pm and tickets at £12 with concessions £10 are available from the box office on 01582 767525 or visit www.harpendenpublichalls.co.uk
