Subject to change but just seeing MB's demeanor and reading everything else that happened, I think MB drowned EB and buried her somewhere in mid-December. I think she fell in "love" with HW and HW said something like I like hanging out with you but I'm not interested in raising someone else's kid... and MB murdered EB and told HW the baby was living with her dad now. Even though MB seemed like an ok mom from the photos, she may have thought she'd just have another baby with HW and then he couldn't leave her. According to the USA Today story, AB and TBSr broke up repeatedly and each time they got back together AB got pregnant again...until the next breakup. MB grew up seeing that a baby keeps your man (at least until it doesn't). It didn't work with EP but maybe it would work with HW. JMO, pure speculation!
