@Blonderabbit Good points here.
Claudias phone was reported as turned off within a 9 mile radius of the Uni because it would have communicated with the UNI mast. This is quite a big area.
Separately, her phone was detected connecting to a different mast in the weeks leading up to her disappearance in the Acomb area.
The two phone triangulations were different.
The first SIO Galloway stated that he knew where Clauias phone was on 18th 19th. The second SIO stated that they could only be accurate within 9 Miles.
Galloway was using "Kidology" and to put the presure on as
@Blonderabbit states.
Unfortunately police don't have her exact positioning on 18th /19th and on phone turn off they can only say that it was within 9 miles of Uni mast.
CL may not have been with her phone when t was turned off. She could be miles up the motorway.
