My recollection of events is slightly different from yours. I recall a leak in 2019 which released the press hounds from what had been up until then a closely guarded line of investigation.As I recall, back in 2020 it was going to be all over by Christmas.
IMO they totally misjudged the value of their evidence, but as he's the only suspect they've got, they wish to hang onto him as long as they can.
Ultimately they'll run out of leads to investigate and they'll need to charge or accept defeat.
Mea culpa! I originally thought the leak had emanated from the PJ as per the norm from the first months of the initial investigation.
In retrospect I realised that the BKA and SY had pulled off the near impossible feat of
- investigating a crime
- investigating a criminal
- gathering and collating evidence
- building a case
- charging the criminal
- bringing the case to trial
- which resulted in a guilty verdict and a custodial sentence
Who had heard of DM or the invasive outrages CB carried out on her body by CB until it was made part and parcel of the MM case because the perpetrator was the same man the MM detectives had under discrete investigation.
If CB's name had not been put in the public domain when realisation dawned of who he is we would have been ambling along in total ignorance of him at this point in time and investigators would have been allowed to get on with the job in hand.
Just as they had been allowed to do with the DM aggravated rape case when no-one apparently knew about CB's association as suspect in MM's case.
My opinion
