I just don't think that boat launch is one that someone would "accidentally" happen upon. Even if she had wound up in Saraland on accident, there are plenty of exits along the way she could have used to turn around on. I know that at this point anything is possible, but IMO if she drove herself to that specific launch it was intentional. I just don't think she happened upon a random boat launch, that you travel through neighborhoods to get to, and accidentally drove off in the water. I just rank that really low on the possibility list.
This could be absolutely unrelated, but in looking for any updates I stumbled across an update from
Cassie Fambro stating there was a heavy police presence at Summer Chase Apartments in Mobile. These apartments are located near Medal of Honor Park, which if I recall correctly was a place that DNV liked to take CT.
