Sorry for the late response!
Of course, a similar modus operandi is a strong verdict for a court. And i mentioned a possible modus operandi as a key to solve this case pretty early. Until today, we have a single case (DM) with a special modus operandi linked to CB.
IF the prosecutors could link CB to the HB rape with a legally binding sentence, it should be kind of "easy" to convince the court, that possible evidence in the MM case with the same modus operandi points out to CB as the most likely perp!
But not just if there might be existing footage, even if there are a few confessions of CB made to witnesses over the years, of having done the same with MM.
The fact is, that CB seemed to be somebody that liked to put his deeds on tape. So IF he raped and tortured DM and HB with a same modus operandi, there should be some footage of both crimes. I personally believe (not more, not less!) that he sold it on the darkweb and the web doesn't forget anything.
IF i'm right and CB did the same to children like MM, there must be footage of it somewhere around the virtual world, or somewhere dug up in shabby places.
