Thank you so much for posting this recap!
Very interesting....
SO, why was this neighbor so tuned into her comings/goings....?
Not to cast doubt onto her...just: if she was, & appears have been indeed, keeping 'tabs' on SM - why?
Again, my speculation is that she was worried/concerned for SM's safety - NOT that she has anything to do with her disappearance
Point being: she had a reason to worry for SM - why?
She worried to the point that SM, allegedly, didn't return back from a bike ride that very day & she is compelled to call 911
Interesting.......
JMO
ETA 'tabs' bad phrase - just - how many see their neighbor leave & then are aware enough of when/if they've come back to go check/see, keep a lookout, & then call 911...she was being fairly vigilant: for a reason....presumably she knew SM could be in trouble.....maybe SM was aware of a stalker......?
