The whole LinkedIn thing makes me think this is CG related. Who uses LinkedIn except people who need to network? Especially MLM ones? I never used LinkedIn, but I'm old and retired so maybe it caught on after I retired. Maybe it's the new Facebook for working people. Do regular 9-5 working people have LinkedIn? Sorry to be old but I don't think LinkedIn is used by the average blue collar Joe/Jill or secretary. Or old people.
Sending a LinkedIn "creepy" message from an unknown person, while people were going out of town to a CG conference, makes me think this is a wife who is savvy to the whole LinkedIn networking set up. And it could be there were creepy messages before the Austin conference, and this is why Missy wasn't acting herself, as her gym pal stated.
