I have seen several timelines in which he reportedly called the salon at 3:30.

I believe that the early timeline was based on some misinformation and assumptions. The earliest was that he got home at 3:30pm, called grandma, then grandma immediately called police... and the brother texted where are you "presumably" because he had heard from grandma (Thank you Nancy Grace) Since them they have slowly changed it to everything starting at 6:50, and that the text from the brother was also to two other people for a ride, and the phone call has dropped in at least one timeline. That is my current understanding. Of course it wouldn't surprise me to see a new article out saying something completely different. :banghead:
