Apparently the extra key in the shed or whatever, (I can't remember were it was kept now?) was missing from its usual place? Does anyone know if the key was in the lock on the inside of the door or not? Because I have read somewhere that the door was locked from the inside?
Going to be picky here as Grahame's post may mislead people due to bad wording.
Grahame refers to "the key was in the lock" .
People may wrongly get the impession this was the spare key talked about when it was not.
Grahame should have stated "a key was in the lock".
People need to be careful not to change evidence or incorrectly report it in a way that may inadvertently or otherwise mislead people.
