I am thinking that the location where the body was found,
the fact that she had her clothes on, and being put in a garment
type bag or what have you, speaks to the mindset of the perp.
Seeing that she was just not tossed naked to the side of a road, in the woods etc tells me the person DID indeed have an obsession with Sandra and maybe in his own sick mind had some feelings for the little girl also, or maybe just feelings for himself as
gross as that sounds, felt guilt afterwards,and took the time to dress and put her in that bag out of some twisted kind of guilt. Maybe it was guilt mixed with the knowledge that if she was found, she should look decent because the perp has so much to lose. I'm not sure I'm making sense here, but my point is, his concern was not for Sandra, but for himself. How much more horrible would it be if she was found naked along side the road, then if she was found all neat and tidy, in a container, fully dressed, apparently even with her shoes on? I mean after all - he has a reputation to protect, he can't just discard her like some kind of monster, now can he?
Also, the place he chose , he knew she would be found sooner
than later, being that it is drained. He may have thought the case would sink in the mud. He may not have known that the bottom was not just goopy mud. He WANTED her found! I've seen a couple of posters say this and I'm not sure what I think about it, personally. From what LE said, it would be reasonable to assume the perp had some knowledge of the area. Which implies to me that the perp would also know that the basin is drained occasionally. If the perp did have such knowledge, then I would agree that he wanted her found. Unless the perp was thinking she would sink in the mud. Because the basin has been described as both a drainage basin and a sludge basin - I'm not sure what the perp might have thought. If it is indeed a sludge basin - he may have been thinking mud.
She knew him, she trusted him; AND he knew this!! I think she really did know him, I'm not so sure she really trusted him. There is a look/mannerism you can pick up when watching the video when Sandra looks towards whatever it is that grabs her attention, she moves her hair behind her ear and she has a look on her face, then she briefly looks towards her house, and to me, I think she is thinking, its okay my house is right there. Thats what I pick up out of that gesture she makes - ahhh okay, I can talk to him, I'm home, its okay. I, of course, could be totally wrong about this. Other posters seemed to think she was acting exactly the opposite - okay, nobody sees me, I can go.
Guilit, guilt, guilt...but he couldn't stop himself!!! I'm with you here 100%. I think he does feel guilt. Guilt for not restraining himself, guilt for risking everything. AND I think he is now scared that he might indeed lose everything.
Just my thoughts...
