There are 2 people reporting on Twitter that someone has deleted some of Sierra's Twitter posts. Don't know if it's true though.
I did some digging on Twitter, and some tweets about Sierra are just weird... Like creepy. Especially one guy in particular, writing more than 1000 posts about her. Maybe it's just me being paranoid, but it makes me think of these cases where the murderer/purpetrator is being active and helping in searches and so on... The hero syndrome.
I'm not saying that it's bad to spread the word, but it's a very thin line between helpful and creepy. I hope that FBI is looking into the "social media world".
There are weird people hiding behind screen names on Twitter. I discovered something very interesting last night. It's like one post leads to another and another.
And then there's the twit about someone sending 15 messages to Sierra on the 15th, but nothing on the 16th. Don't know how reliable that is, though. The posters who are following Sierra's friends go way over the top, and just add to their concerns about Sierra. Twitter has no rules, according to its website. Let's hope LE is monitoring closely.
