kids who think they're just playing dealer....(?) first, they're not kids. Again, if you're selling a pill, you're dealing, as far as image goes, they have forever ruined what image they think they have.
About the burner phones, I get it. If they are thought to have burner phones, then, they could have be in contact with any of the POIs that night. It opens up a lot of possibilities. But, that's just what I am proposing. I think, speculation, speculation, speculation, that they did have them or some other means of communicating under the radar and that's just what they did. and, IMO, not only could they communicate under the radar, but, IMO, speculation, they also knew EXACTLY how to avoid the cameras. We didn't live under the camera scrutiny that they did, so we keep being amazed that they aren't seen on camera doing anything to Lauren.
So let me recap: they communicated w/o being heard; and they went places w/o being seen, and; they weren't super lucky, but knew how to do this.
And it doesn't take a genius or any kind of super power to do this.
If they were poor, and had no money or power behind them, I would still want them ruthlessly investigated until they were eventually prosecuted. Granted, they are young, and everyone with children probably cringes to think there but the grace of God goes our child, but it doesn't change what happened. If one of the POIs did it, or a combo of them, they need to go down with no mercy, even if they were just "playing" dealer.
