Maybe as Claudicici suggested earlier the person texting was Syniister afterall, I had first taken piXy's quotes to imply that it may have been Stitchmouth but she quickly came in and corrected us on that theory.
2 things to consider with Syniister, he definitely has been affected by this more so than most and to the point he has basically shut his WIR business down posting comments to the effect he felt somewhat responsible for influencing Sam and would no longer produce horrocore.
Also, keep in mind that the record clearly shows that Sam and Syniister were best friends and were likely the closest within the community and Syniister would definitely be the person Emma would contact if she were having problems with Sam. MAYBE IT WASNT ABOUT FLIRTING WITH ANOTHER PERSON AT ALL and was in fact Emma texting Syniister behind Sam's back to GET ADVICE from Syniister on how to deal with the fact that IT WASNT WORKING OUT and LATER Sam found those texts and felt betrayed by BOTH the girl he was in love with AND his BEST FRIEND and at that point felt he had nothing to lose, decides to go out with a bang and kills them all and then CALLS Syniister to let him know that he killed them all, perhaps even sending pictures just to rub it in. Syniister perhaps then, extremely upset and feeling somewhat responsible, calls Shrim and says wtf do we do here? Shrim then calls authorities after possibly seeing pictures sent to him by Syniister.
THERE IS A REASON SAM CALLED SYNIISTER AND IT WASNT BECAUSE HE WAS SCARED IMO.
This is of course only my opinion and what the evidence KNOWN PERHAPS SUGGESTS and I am by no means implicating anyone who may otherwise be innocent. The above is speculation and for discussion forum purposes only.
BTW someone earlier also suggested that it may be this Kuriouz character who was texting Emma and piXy earlier in our discussion already said it was not him and that he and Emma are long time friends and there was no romantic interest between the two, so I think we can rule him out.
BTW to everyone GREAT sleuthing work on the Shriminator (ty Ziggy!) and our new friend Lizette Moreno (Howdy Razzy!).:snooty::snooty:
