Oh yeah if there was a found phone with direct communication between some of the names listed to the alleged perps arrested in 2014 then with a few more joining of dots the police may have got it through the CPS although still mainly circumstantial.
I imagine phones were still seized in 2014 and contacts list looked at but guess they'd be denials and no firm evidence of links related to CL's disappearence.
It's an intersting angle anyway straight in from a newbie on this forum. Long term lurker I take it?
