I am still puzzled by the rumor that some combination of JR, CR, and MB were out looking for LS, possibly before JW and HT had reported her missing. If JR and MB were telling the truth (CR isn't saying anything but he allegedly asked someone if they'd seen a little blonde girl), they'd have no reason to think that she did not make it back to Smallwood. If she OD'd and they did something with her body, why would they go out looking for her?
What if one or more of them left her outside, unconscious at least, maybe dead or dying, figuring that she'd be found soon but her death or OD would not be blamed on them?
Then when there are no sirens during the night, they are puzzled and figure that she must have gotten up and walked away on her own. But even in this scenario, how would they know that she did not make it back to Smallwood.
