John Bass convicted of manslaughter of Mark Austin in Aylesbury
A 50-year-old from Buckinghamshire has been convicted of the manslaughter of a man described by his family as a "talented musician".
Mark Austin, 53, died in hospital the day after a fight in the Harcourt Green area of Aylesbury on 31 January.
John Bass, of Arundel Green, was found guilty of killing Mr Austin after a two-week trial at Reading Crown Court.
Bass, who had denied murder, is due to be sentenced at the same court on 28 March.
While he was in custody, Bass was sectioned under the Mental Health Act.
He was charged with Mr Austin's murder last May.
Police had been called to Harcourt Green after reports of an altercation between the two men.
Mr Austin, of Coxhill Way, Aylesbury, died on 1 February last year at Stoke Mandeville Hospital.
Det Ch Insp Kevin Brown said: "John Bass carried out a sustained attack on a man who believed him to be a friend whilst drinking socially with him and another.
"The victim, Mark Austin, was physically a much smaller man than his attacker and was left with a severe injury by the assault from which he died a day later.
"This has been a very sad case that has left a family mourning the loss of their son and brother."
