BTW, if you compare this case to say, the Jessica Ridgeway case, you can see how the earliest stages of an investigation are extremely important. And the old ways of doing things aren't working so well in this modern age.
LE in the Ridgeway case were fairly open about what they had. They had regular press conferences and cleared the family. They released vital information that actually broke the case...that unforgettable photo of the wooden cross. Within days, they had an arrest.
This case was a mess from the first moments. So much confusion and frustration. After all this time, we still don't even know who made the 911 calls...and we aren't allowed to hear them. That, alone, would help so much.
My prayer is that somehow, some way, this case will be solved in my lifetime.
