In 2005 CB journeyed from A to B carrying his rape kit. There are no witnesses to this.
He then uninvited and illegally entered a villa and proceeded to torture and rape the occupant over a prolonged period.
The only witness to this outrage was the raped and tortured survivor.
There were no witnesses to this weirdly dressed man's entry carrying his rape kit. There were no witnesses to his exit carrying his rape kit and his victim's computer.
Had he chosen to take his victim with him there would have been no evidence as to what CB had done in the villa that night short of a window covering. And who would have thought anything odd about a window being covered or attach much significance to it anyway?
CB escaped the consequences of his actions in DM's villa until his name was given to the German police in 2017. Ten years after MM was kidnapped from a scene with no apparent evidence and twelve years after DM was assaulted within her own home with no apparent evidence of an intruder.
But although MM was not around to tell her story there is absolutely no mystery about what was going on in the Algarve at that time.
The only mystery about it is why the Portuguese police didn't choose the home invasions and assaults as an obvious line of inquiry which turned out to be so much worse than initially thought when investigated by SY.

Police investigating the disappearance of MM
n from a Portuguese holiday resort nearly seven years ago say a lone intruder sexually assaulted five girls aged between seven and 10 in the Algarve between 2004 and 2006.
The four incidents – one involving two girls – were among 12 over six years up to 2010 being examined by officers in which a man entered holiday accommodation, mainly villas occupied by British families.
