Out on a tangent here so I'm not taking up for anyone.
There was talk earlier of Keepers and/or DE trolling Nicole. Take Keepers out of the equation. It's hard to since we already know she's tied to the case and spilled some beans. Could someone have been talking to Nicole pretending to be DE? Essentially both Nicole and DE would be trolled in this scenario. Someone could have established a Kik account ghosting as DE...complete with name and picture.
I don't think this theory plays into this exact case, but it's a far fetched idea that more than one people could have possibly been trolled. Of course LEO would have to trace the IP exactly to respective phones and computers. And thankfully things can be traced even if deleted.
I bring this up from personal experience. A disgruntled guy has cyber stalked me for years. He went on to establish fake FB, Twitter, classmates.com,etc. accounts with my name and picture. He was trolling me by pretending to be me.
