The change of heart came about following a police interview with the murdered burglar’s accomplice. Originally he had said that he had been chased by Mr Roberts after he had been stabbed. His story has now changed and he admits to waiting outside the house whilst Mr Roberts and the murdered man fought. He also now admits to having a knife when he had previously denied being armed.
The prosecution relied upon this boy’s evidence to secure a conviction. His radical change of story means any evidence he may have given would be discredited.
By the way, AOG, Tony Martin was originally convicted of murder and sentenced to Life. Upon appeal his conviction was reduced to manslaughter for which he got five years.
