The timing of the telephone calls is a very interesting feature of this case, and it depends which references you refer to, on whether or not, you say for example, that JB contacted the police, at 3:36am, or 3:26am, or 3:10am, or even earlier...
Similarly, when looking at the question of when JB contacted JM that morning, it again would depend upon which references you chose to rely upon, as to the timing of that call, for example, 3:30am, 3:15am, or earlier at 3am?
There appear to be so many inconsistence and discrepancies surrounding these phone calls that no-one can accurately pinpoint when either of these calls were made, not the police, not Julie Mugford or her friends, and neither JB...
If JB is lying about the timing of the calls, then so are the police and Julie Mugford, and the others who refer to them - You cannot just single JB out and say that he is and has lied about the timing of the calls...
At, least not in my opinion...
