To me, if the girls named a name, it seems like they'd be strongly investigating certain people! But if all they had was a first name, they'd need other proof to arrest still. Interesting to consider this though! What if they are right now doing surveillance on someone named (or partially named) in the video? Or what if they have someone locked up on other charges while they look for evidence that corroborates an individual whose first name was dropped.
I suppose it's possible they named someone. I never considered this. Another question a reporter could ask Le!!
Was thinking this afternoon(JMO) that there being a "twist" in this case that maybe if one of the girls did survive for a while and maybe she left some kind of message (in the dirt, leaves, etc.) for whoever would find them. Maybe even a short video before she died.
