I don't find it as weird that her daughters weren't physically there with her at the house on MD, given that we're hearing the older one was away at college and the younger rumored to be off on a camping trip for the weekend, covid social distancing rules notwithstanding.
What I find extremely odd is that we're not hearing that either of her daughters OR her husband attempted to contact her that day to wish her a happy MD.
One would think if there were calls or texts to her cell that went unanswered that day, LE would have included that info as part of the known timeline surrounding her disappearance, i.e., "One of her daughter tried to reach her earlier that day but her phone went straight to v/m, etc."
I'm finding it much too coincidental that she was apparently home alone for the weekend when she disappeared.
I also suspect it was a family member who contacted a neighbor and asked the neighbor to contact LE.
And if that's the case, that's just flat weird.
JMO.
