Read the interviews of all the subjects that LE met with and consider if they are deeply detailed focusing on the subject being interviewed or if they focused on Casey. It is very plain that LE fixed upon Casey the day they first met her and focused heavily on her in all interviews. While they may have considered other suspects briefly, perhaps as conspirators, LE did not research others in the kind of detail they subjected Casey to. This is because they arrested her so quickly that she hired a lawyer and stopped speaking to LE. Unfortunately, situations like this can be used by attorneys to create reasonable doubt in juries minds.
Since the family (including KC) agreed that she was the last person to see KC... Who besides KC should the LE been talking to?
What happened to KC the first day, is pretty standard. It's called "Questioning" of witnesses. She wasn't the only person questioned at first.
Cause the way I read the first day, they HAD to focus on KC the first day. To get her story, to pick her head for any information they might give them. So they can track down that baby.
That focus on the first day wasn't because she was real suspect. Everyone is considered a suspect at first. But because she was the last known witness, she is considered to have the most useful information. Normally that would have given them something to start with. That would lead to others involved to talk with. But the LE was stuck with KC, cause she didn't give them anything but lies. They questioned her some more, and they got more lies. They followed every lead she gave them. Not to 'catch her'. But to find the baby. To recreate the picture. To find other witnesses to the event, etc. Hoping that it would lead to the persons who took her.
IT is from the questioning that the LE get their leads to track down others to question. To find evidence, etc. Other wise, why didn't they question you or me? They don't just go grabbing folks of the street, in any ole town, and start questioning them.
KC talked to the LE alot, and gave them lots of info to check out, before she was considered a prime suspect. Even when the LE was calling her on her lies, doesn't mean they considered her the prime suspect yet. But pointing out she is lying in hopes she will tell the truth. Which would give them info to find the baby.
We can't blame the LE for not coming up with SODDI. They followed the leads given them.
Which brings me back to my point. It isn't that you can't discuss SODDI besides KC. It's just that when you make an insinuation that the LE focused only on KC that first day, and use THAT as the bases of your theory.. you need to expand upon that more. Since the point of this thread is to discuss SODDI, any theorys are going to be picked apart to figure out how probable it is. Since you have thought about this, what should the cops have done?
