THE ex-girlfriend of a doorman accused of murder claimed he admitted stabbing a drunk in Chester city centre during their relationship.

Katie Couchman, a hairdresser, of Ashton Drive, Frodsham, was giving evidence in the trial of Scott Davidson, 23, and co-accused Rachael Horton, 19, at Liverpool Crown Court.

The former lovers deny murdering 49-year-old Martin Ithell, of Boughton, Chester, at their home address in Hawthorne Road, Frodsham, where it is alleged he was shot and stabbed.

Miss Couchman, under cross examination, recalled a conversation with her then new boyfriend Scott Davidson in the spring of 2009 as they were walking through Frodsham when he was a doorman in Chester.

She said: “I ramble a bit but he was quiet and I said “What's wrong?” He said “I don't want you to judge me”. I said “Just tell me what's wrong”. He said “I stabbed someone”."

Miss Couchman, who lived with Davidson in Helsby for a short time, understood the incident related to a drunken man having kicked a wing mirror off Davidson's Vauxhall Astra near Eastgate Street.

She confirmed being told the drunk had passed out in an alleyway when Davidson grabbed a knife he kept in his car and stabbed him.

Andrew Thomas QC, for Horton, said: “I think he told you the police were looking for him in relation to that but had not found him?”

Miss Couchman, who split up with Davidson in April 2010, replied: “As far as I know.”

Earlier Miss Couchman was asked about seeing Davidson walking along her road on a Friday evening which the prosecution argues was immediately after the alleged murder on March 11.

Prosecutor Michael Chambers QC has previously said there was a clear inference the defendant was “disposing of items” such as the overalls he had worn at the scene, although nothing was ever found.

Miss Couchman could not recall the date but remembered Davidson looked up at the helicopter that was hovering overhead and also that “he smirked”.

The trial continues.
