The man who helped convict notorious double-killer Michael Stone was this afternoon convicted of murder.

Eight years ago Stone was found guilty of killing Lin and Megan Russell in Chillenden – after Damian Daley gave evidence for the prosecution.

Daley told the court that Stone had confessed to him in prison that he had carried out the dreadful attacks on the 40-year-old mother and her six year old daughter in 1996.

The jury was not told of the Stone case after Judge Adele Williams placed a ban on the Press mentioning the link between the two.

But this afternoon, after deliberating for most of three days, the jury convicted Daley of helping in the murder of drug dealer Gus Allman in Folkstone.

They also found Timothy Avril guilty of stabbing Mr Allman seven times and found two others of perverting the course of justice.

Two others have already admitted their part in the incident and all six will now be sentenced next month.

As the jury returned its verdicts, Daley began shouting: “I didn’t do nothing. This is all wrong. I didn’t stab anyone”.

At one point he turned to where members of Mr Allman’s family were sitting in the public gallery and told them: “This is all madness. I didn’t stab him.”

During the past month the jury heard details of how a bust-up over drugs led to a 20-year-old Mr Allman being stabbed inside a Folkestone flat.

A doctor was flown by helicopter to close to the M20 to join the battle to try and save his life but he died from his injuries.

Drug-dealer Avril, 22, and pal Daley, 39, had denied murder. Avril admitted stabbing Mr Allman but claimed it was in self-defence and Daley said he was in an upstairs room and took no part in the killing.

Prosecutor James Mulholland QC revealed how Mr Allman had arrived from London in an Audi at a flat in 20, London Street in Folkestone shortly before 7pm on February 19.

"He died two hours later at the William Harvey Hospital in Ashford," he said. "He was 20 years of age. He had been stabbed seven times inside the flat

A doctor was flown by helicopter to close to the M20 to join the battle to try and save his llife but he died from his injuries.

Mr Mulholland said that Avril "was by his own admission a drug-dealer" and police later found wraps of cocaine at the Dulwich home he shared with his mother.

He told how Avril travelled frequently from London to Folkestone to supply drug addicts and used the flat in London Street as a base.

"He rented Flat 2 from Laura Smith and used it as a base for his drug dealing activities. Laura Smith lived there with her boyfriend, Damian Daley," he added.

Smith, 27, now of Harvey Street, Folkestone broke down and was led from the dock before the she was convicted by the jury of perverting the course of justice.

Dean Alford, 20, of Wadden Hall, Canterbury, and passenger MelechMarshall, 18, from New Cross, London had admitted charges of perverting the course of justice at an earlier hearing.

A fourth man, Michael Williams, 20, from East Dulwich was also found guilty of perverting the course of justice.

All four were remanded in custody pending sentence shortly before Christmas.

Judge Williams then praised the police for the investigation and also the family of Mr Allman for their "dignity and restraint" during the month long trial.
