Man convicted of murdering guard

Paul Cavanagh was stabbed to death on 18 December 2006

A 20-year-old man has been found guilty of murdering a security guard.

Paul Cavanagh, 30, of Rockland St Mary, Norfolk, was stabbed to death on 18 December, 2006, at the HMV store in Chapelfield shopping centre, Norwich.

A jury at Norwich Crown Court found David Watson, of Hackney, east London, guilty of murdering the guard.

Watson, who had denied murder, said he stole a CD from HMV as he thought he would get away with it, but he was challenged by Mr Cavanagh.

Watson was also found guilty of wounding a second security guard.

Sentencing was adjourned until Tuesday afternoon.

David Watson, of London, will be sentenced on Tuesday

The court heard that Watson had a bag with him containing £1,400 of hard drugs, and he was worried that if they were discovered his dealer - to whom he owed money - would blow up his mother's house.

He said he did not realise a knife was in the bag.

Watson said after he was challenged by Mr Cavanagh he took the knife out to "scare him and escape".

"I did not intend to harm him with it," said Watson.

The two struggled and then fell against the door, he told the court.

"I go to get up and looked down and there was blood everywhere. I do not know what happened," he said.
