Tybee you will never be forgotten
It seems improbable, but not impossible, that Sierra has run away even though some of her tweets on her Twitter account suggest she wanted to be somewhere other than home and I doubt this is a case of stranger abduction. If she is a runaway then LE would have made that official by now and they would have sent a bulletin about her runaway status to all of the other LE departments and to agencies specializing in runaway cases.
As I said, it is not impossible that she has run away from home but it is not certain because she does not have a history of running away and she was too much into school lately and being with her friends to simply run off somewhere without telling at least one of her close friends either in Fremont or Morgan Hill about her plan.
Sierra's home is located at the end of a dead-end street with very few houses located in her neighborhood. A complete stranger would have to go entirely out of their way to drive that far into that part of California to abduct her and risk getting caught or noticed on that type of street unless it is a psychopath who became obsessed over her, especially someone who came across her on one of the social networking sites. Some of the people on her Twitter account give me the creeps.
If Sierra was abducted then it has to be either someone she knows, maybe even someone from her past that no one would expect would do something criminal, or it could be someone in the area of her home who noticed her and knew her daily routine just by observing her and her mother and the mother's boyfriend from afar over a long period of time.
Sierra did describe on Twitter an incident that twice happened (February 23rd and 24th) concerning a car with people who were bothering her. That is something LE cannot and should not rule out as part of their ongoing investigation.
LE seems to have narrowed down their case because they have not, as far as we know, extended their search beyond the country where Sierra resides. Have they questioned the faculty and students at her former school in Fremont? It seems they have focused attention only on her current school in Morgan Hill. Maybe LE has an idea who may have abducted her but they have to get their evidence together and observe any suspect or suspects for a long time before they can make an arrest?
Does anyone know what happened to Sierra's last tweet on her Twitter account? The linked account in her last retweet is @AlexiaIsom, but if you click on the link it says "this user does not exist". I could be wrong but I believe it has been like that for about a week. Isn't that suspicious?
These types of stories are personal to me and they bother me a lot because I was almost abducted when I was a child over 30 years ago. It was the most frightening incident that I have ever experienced in my life.
Sierra and her family and friends are in my prayers. I pray daily for her safe return home.
From what we have heard the L/E has interviewed all Teachers and Friends of her from the school in Fremont.
