The “confession” even if it was, which is questionable — is meaningless. The man who made it is a murderer, a person who is murderer can not be trusted in any sense. It is NOT reasonable to have a doubt on the basis of a “confession” of a murderer.

Are you saying, if you were on a jury and one defendant were to confess to being the only one responsible for a double murder, it would have no bearing at all on your decision? Was there any other exculpatory evidence? I am not familiar with the details of the case.
