I wonder though if Police have been able to collect all the phones or even know of all the phones that were used? They also could have used burners and ditched them? Maybe that is what the metal detectors were for?
I'm also curious of the route taken from NC to Hartford? NCPD asked for CCTV from folks near the Merritt but the northern most entrance to Merritt is Rt 123 and this can also be used to head to Ridgefield, up Rt7 and get to Rt84. Ridgefield and Redding police I believe do use the license plate scanners so I wonder if they were able to get any confirmation of FD/MT route to Hartford using this technology?
