I have that same question.
I need to actually watch that FB live she did myself if it's still posted.
I'm not entirely confident that LS didn't misspeak or misquote LE in that live.
Having read some of her tweets and articles, I think it's entirely possible that she may have unintentionally misspoken. That's not a criticism of her.
Nobody's perfect.
Misreporting happens in MSM.
I'd prefer to hear it directly from LE that SM was last seen later than they originally thought she was seen.
I'd also like verification from LE that this was a verified independent sighting, as opposed to BM saying it was the last time he saw her.
Of course, the difficulty with that statement, even if accurate, is that LE hasn't come out and told the public what time they "originally thought" SM was last seen, so we're without any frame of reference.
If a true statement, it's an interesting one.
I have my doubts as to the accuracy of it.
JMO.
