'We're very sad and angry' Quest for answers a year after son's Mexico death

A year ago this week George van Day, a 26 year old from Brighton, died following an attack in Mexico.

Ever since his parents have been desperately trying to find out what happened to their son, who suffered from Asperger's Syndrome.

A coroner in the UK found that George died as a 'direct result of an assault' - but his father says he's disgusted by the lack of effort from authorities to track down his killers. Andy Dickenson reports.
