After much debate, it was "decided" that the photo (which was taken by iPhone the morning after she disappeared) was taken by a reporter, or even her mom, of the photo "Sherman" *LOL* (Sierra) herself had posted before school the day before. What was confusing us was that that the information tags on this image showed it was taken Saturday a few minutes past 10AM, until we collectively realized that this was not the ORIGINAL transmission of the photo, but a photo snapped of the computer screen by the reporter/Marlene. The first time she spoke with the press was Saturday at 10, at her home (which is why the location tag was right).
I attributed the photo to LE owing to the fact that every officer in that department is issued an I Phone. Also, I do not think that reporters would be given access to the home. My thoughts are that LE shot the screen, and then unplugged and took the computer with them for further investigation.
