David says he turned on the washing machine after his paper run, and says he sorted the clothes, whites from colours, but he didn’t leave out the hand-knitted jerseys. The family practice was for those to be hand-washed. Margaret was very particular about the care of these, as was David who, while on remand, had all his jerseys hand-washed, because he didn’t want them to be spoilt by the prison laundry. There would have to have been a very unusual occurrence for him to machine wash the green jersey on the morning of the murders.
