On a January evening two years ago, Pietro Addis dialled 999 and told the operator: I m calling to hand myself in. Asked what he had done, the 17-year-old simply replied: There s been a murder.
Sue Addis, 69, was found at her Brighton home with 17 stab wounds by police after grandson Pietro (pictured) called 999 to turn himself in. He was found not guilty of murder by a jury.
