Susan would NEVER leave her kids with that emotionally abusive failure of a man. There is only one reason she would leave her kids, and that reason is murder.
Even the people most likely to hold out hope for a miracle situation, Susan's family and friends, know what really happened here.
Every day that man spends free might be his last. I know that one day I'll wake up to the news that I've been waiting for, and I'm willing to keep waiting (however impatiently) for justice to come; but there is no doubt in my mind that justice IS coming.
