A Cornish fisherman who attacked a man who later died has lost his appeal against a murder conviction.

A Cornish fisherman who attacked another man who later died has lost his appeal against his conviction for murder. Brian Harrison attacked Neville Dunn with his fists and feet in Penzance in December 2007, causing a devastating brain injury. Harrison was convicted of GBH and sent to prison.
Mr Dunn died from his injuries in October 2009. In March this year, Harrison, from Newlyn, was found guilty of the killing. Harrison appealed, claiming that evidence of the GBH conviction should not have gone before the murder jury, but the Court of Appeal rejected the claim.
The judges also refused to allow Harrison to appeal against the original GBH conviction and upheld the 16-year-minimum term he must serve.
