Were you able to conduct analysis on the photos - in terms of how many of each child? The results are indeed indicative of
something.
We may disagree on what that
something is, but there is no doubt that the ratio between the two children's photos is off the charts in one direction. It's not even close.
This same analysis can be done on her FB postings as well, with the same results.
Not that favoritism leads to murder, but with all the other information in this sad case, it certainly could this time.
FB and other socmedia is being used more and more in criminal investigations and the use of them in this regard, will rise and rise and rise.
What comes to mind for me when I read, for example, answers to different surveys SOME PEOPLE take on FB at different times, is something akin to the
MMPI.
That instrument will ask different questions throughout the inventory where the questions are so far apart and are slightly tweaked, that it can reveal more about a person, even though they know their answers are being assessed. It can reveal discrepancies and contradictions just by spacing the questions far apart. The MMPI is loooooong.
So whether it's info from various timeframes on FB, info from various LE interviews/statements or polys, information told to friends or teachers etc, all of it can come together to reveal contradictions over time in one's story. This undoubtedly plays a role in how and why LE focus on certain people.
Just my opinions.
