Good coverage but it's painting a picture I can't quite see yet;
<snip>
"But you just heard it. She stopped posting on Facebook. What would cause Danielle, a typical 15-year-old, to stop posting on Facebook in the weeks before her disappearance? "
I don't see this as accurate, even quite an exaggeration. She had posts on her FB as late as 3/7, Others were posting on her wall and she was liking and commenting. Going back to Christmas she was initiating more status updates herself, but that is a busy season and many people just wind down after the holidays.
She had that one period where she started a new Facebook page on 12/30 but only used it that one day. She had posted "time to start over" but then went back to posting on the original page.
I see ups and downs in her relationship and I see ups and downs in her activity.
But I don't see anything alarming and I don't see that she went silent on SM.
I Do, however see a 'typical 15 year old'.
What am I missing?
