(Okay not the best source for info, BUT...)
Something I found in that video that is VERY interesting to me, is the discussion about verizon and their restricted service. If a call was made from a restricted verizon phone, the call would be re-routed to verizon customer service, and they would have record of that. So, let's say for a moment that DB wasn't lying about the phone being restricted. Is it possible that someone (possibly an intruder) tried to dial out on her phone, the call was re-routed and verizon had a record of it, and this is how LE was able to trace the call to MW?
I honestly don't know...cell phones are strange magic. They confuse and frighten me.
