Kik app? It is a magnet for pedophiles. And no, it doesn’t keep any information.
In the story linked, kids were sexting via Kik. Can you imagine how easy it would be for an adult to lure the child using such an app? For exploitation, or to kill.
This is how these pedophile killers find victims, and no, Kik keeps nothing.
Westfield police warn of children sexting on Kik app
This is why I say 2006 was too long ago. If there is a connection between a killer and a victim, modern apps successfully hide it.
ETA: not meaning to establish connection between any app and the girls specifically. I merely think they were modern, tech savvy girls, using the same apps as their friends. but this very factor might be working against the case now. As to who the BG was, I keep an open mind. Could be someone in their environment, or someone living in the vicinity of Delphi and stalking them, or could be a random stranger. We do need to keep our minds open. This is why I feel TV stations need to show BG, in case he is a stranger. But I assume he could be linked to them as well.
