I just can't shake the feeling that her disappearance has some connection to the note that was left on her doorstep/stoop/porch. Even though the subject of the note was allegedly cleared by LE, I just wonder: How rock-solid was his alibi?
The neighbors complained about a lot who were coming by Sandra's house after news stories were aired. As LE ruled the person out, my guess is it was just someone who wanted to get revenge on someone or was otherwise a nut who wanted to insert herself into the investigation. Lots of crazy people out there.
My current interest is in the 5:00 to 5:30 pm time frame on Wednesday. Just off the top of my head, I'll break this down based upon what we know (or think we know).
1. SIL dropped her off at 5 as he says, and even though he didn't watch her enter the house, she either left the door unlocked, had a spare key with her, or didn't give her house key to the mechanic and she entered the house without difficulty. When Cousin T called at 5:30, Sandra either was outside and didn't hear phone, didn't have caller ID or VM or didn't bother to check either, or simply decided she didn't want to out so never contacted her cousin, despite their earlier plans.
2. SIL dropped her off at 5 and didn't watch her go in. She'd locked the door, accidentally left her only key with the mechanic and couldn't get in (One of my husband's classic moves! He's broken a couple of windows over the years.) Sandra didn't have a cell phone, so her only option was to ask a neighbor to call SIL for her. According to her cousin, Sandra knew everyones' numbers by heart. Upon reaching out to a neighbor, something went wrong and the SIL never got a call.
3. SIL is simply mistaken about the time he dropped Sandra off, and Sandra wasn't yet home when T.'s call came in at 5:30.
4. SIL didn't bring her home.
What am I missing? Somehow none of these scenarios seem very plausible to me, unless it's number 1 and Sandra really just blew her cousin totally off and something went wrong later that night. But if I were in LE, I'd want to know from T. if Sandra had a tendancy to behave like this or had ever flat-out blown her off at other times when they had more or less firm plans. I'm not intersted in what anyone else says about it, she was very close to T. and T. should be able to easily answer that question.
