Yeah, there are numerous interviews where LM says she called Sandra's house on Thursday and Sandra didn't pick up. LM says in these initial TV interviews "it's not like her to not answer the phone", but we learn in The Vanished that Sandra was a major introvert who screened her calls, so now I'm not sure what to think about LM's statement.
The only reason I can think of that LM would omit the T visit was that the investigators initially requested she omit this, and then went back on that for whatever reason.
But if LM really didn't know about the T visit... Sandra did lead a very private life, and I get the feeling that despite the tight financial control her kids exercised over her, that Sandra did her own thing to an extent. It almost seems like most of her relationship with her daughter centered around babysitting and the grandkids. Maybe she just didn't want to be bothered that day, took advantage of her day off, and just didn't tell anyone (including LM) about her plans with T.
...But then again, her SIL did say they usually checked in with her the day before she babysat. And I got the impression that Sandra's overnight visits to T were somewhat routine, so it would seem natural for LM and family to call T if they didn't know where she was. You would also think that if T knew LM and family were taking Sandra's car to the shop before dropping her off, and if T really was expecting her, that she'd give LM or her husband a call on the Wednesday night. But it seems like LM first had an inkling that something was wrong on the Thursday. If I were T, I think I'd also call Sandra's landline a few times AFTER 5:30 PM. Assuming that she wasn't the type to just completely ghost people. But again, maybe these calls or similar communications did take place, and we just aren't privy to that information. LE has every right to twist, turn, and withhold information here if it suits the investigation.
(And the fact that her SIL and LM usually checked in with people the day before, didn't hear from Sandra on that Thursday, and didn't physically go to her house is just weird to me. But that's for another post).
The amount of contradictions and back-and-forths here just makes my head hurt. Something just doesn't add up, and I think the planned sleepover at T's plays a part in this. And that's not even touching on Sandra's car being in the shop.
I remember that Laina had contacted T and asked if she had heard (or something) from Sandra and T had said, 'no, why?' The only thing really about it, other than the phone call incident. I can understand the T visit being somehow troubling.
Also, I think it was Sandra's sister who contacted T, not LM. Nevertheless, the startled "no, why?" reaction seems weird to me. If Sandra blew T off without so much as a courtesy call, and someone asked T about her whereabouts, that just seems logical, and not like something to be surprised about.
Lastly, podcasters are not investigators and they make mistakes. The Vanished also said she was last seen wearing a gray tank top when it was white. It's not inconceivable for the host to have stumbled over her words when describing the already very confusing situation regarding Sandra and T's phone calls.
