The woman who discovered the body of Peter Wrighton in woods in Norfolk cried as she gave evidence in court today.
The 83-year-old was killed while walking his two dogs at East Harling on August 5 last year. His body - which had been stabbed repeatedly - was found having been dragged under a bramble bush.
Alexander Palmer, 24, admits being in the area at the time of the attack but denies the pensioner's murder, despite having a grudge against dog walkers, a jury heard.
Speaking at the second day of the trial at Nottingham Crown Court, Anne Precious broke down in tears as she told the jury she had found Mr Wrighton's body while walking her dogs with her husband, Nigel.
Police Constable Andrew London was one of the first officers on the scene.
He said police initially thought it may have been an animal attack and that the wound to Mr Wrighton's throat was so severe it looked like parts were missing.
PC London said he had seen a "very large pool of blood" across the track which was approximately 2ft in diameter.
Norfolk Police were called to the scene by Mr Precious, who at first thought the body was a mannequin before "reality dawned".
Palmer, of Bawdeswell, Norfolk, denies a single charge of murder. Opening the prosecution case on Tuesday, Stephen Spence told the jury the defendant, who was a former soldier, had previously been treated by mental health doctors.
He had told them how a voice in his head called "Little Alex" told him to harm people or kill him.
The trial, set to last for two to three weeks, continues.
