As for charges, that is the current/next step. Those decisions will be made in the coming days/weeks/months.
For the queue - the evidence was put into a larger 'computer analysis' queue.

I was blessed the case was given to a constable with the right combination of grit, perseverence, and commitment to justice.

A big reason for so many of the delays is that there is no precedent for what happened here.  An Edinburgh department took a case for an American, within the realm of 'Nigerian prince fraud' scheme. As a rule of thumb, those don't get solved.  They patiently took the time to gather and understand the evidence, ask the right questions, and push forward with the case.

This was a huge step in the case.
The next step is critical, as it has the potential to set positive precedents for future cases.

I'll keep this thread apprised of things as they develop.
