Police interviews with Alexander Palmer have been released as the 24-year-old was convicted today of the murder of Peter Wrighton near East Harling.
The former soldier from Cringleford has been found guilty following an eight-day trial of the 'calculated' and vicious murder of the elderly dog walker last August.
The body of Mr Wrighton, 83, was discovered in a remote area of heathland in East Harling on Saturday, August 5 with his two dogs Gemma and Dylan found close by.
He had been subjected to such a violent and frenzied stabbing that it initially prompted officers to believe he had been attacked by an animal.
In police interviews, Palmer appears calm and composed as he admits his presence around the murder scene at the time of the killing 'looks suspicious'.
Asked if he was involved in the murder he answers no comment.
He describes a voice in his head, a 'different Alex' as being 'always there'.
'He used to manifest himself as a physical hallucination,' Palmer says. 'Now he is just a voice.'
Mr Wrighton's family say they feel Palmer was let down by mental health professionals.
Sentencing will take place tomorrow at Nottingham Crown Court.
