Yes (Rhiannon), that's what I read. She'd looked after her husband even though there were pending charges of abuse against him and the whole thing must have weighed heavily on her, with everyone knowing and the pair of them being shunned. He was very sick and she said that he asked her to help him. She telephoned the police and admitted what she'd done as soon as he was dead.
Sririam, it is a very difficult case to judge and - the judge - has to weigh everything up scrupulously. Judges are not infallible, nobody is, but years of experience in criminal cases and assessing character, plus the tremendous weight of responsibility & reputation of the judiciary, means they are generally very wise.
Not everything is black or white. At the end of the day, the only person certain of the truth is the woman who was charged. However it is surely better for a guilty person to go free than an innocent one to be imprisoned.
From what I read, imo the correct decision was made.
