A Home office pathologist told a jury how Connor Barrett died after a stab wound penetrated his lung.

Mr Barrett, from Abyssinia Close, Great Yarmouth, died as a result of a fatal stab wound following an alleged 'joint attack' at a party at Hemsby, on May 10, this year.

Jesse Quaye, 18, of Crittens Road, Great Yarmouth and a 15 year-old youth, who cannot be named for legal reasons, have both denied the murder of 20 year-old Mr Barrett, and causing actual bodily harm to another man.

Giving evidence at Norwich Crown Court, Home Office pathologist Dr Nat Cary told the jury there were four stab wounds to Mr Barrett, but the fatal wound had been one to his left side which had penetrated his lung, causing it to collapse.

'The fatal wound penetrated the lung. The other stab wounds would not have contributed to his death.'

He said that Mr Barrett would have survived the other stab wounds, which included one to his left shoulder region.

He said that there were no defensive wounds to Mr Barrett, but there were some cuts and bruises which might show he had been involved in some type of altercation before his death.

The trial continues.
