I am sure she must be devastated Lugg.
I am also in shock. Maybe he felt unable/and under too much pressure to confess previously, due to all the attention and efforts of SH.. she wanted to believe him and had invested so much time, and emotion, that nothing would convince her otherwise..except Simon actually holding his hands up and telling her/admitting 'he did it'.
I hope Stephanie is okay she must be devastated and in need of immediate counselling as she's spent years focusing every waking hour on trying to prove a 'guilty' man to be innocent
Rest in peace Joan Albert, now her family finally have closure.
