I’m not sure if it’s been raised before but if CB is responsible for the IG and PK crimes (IG missing PK confirmed dead) in addition to MM, is there some connection to the first week of May for him? MM 3rd, IG 2nd and PK 7th.
This is a really interesting point. A significant date in his life? Could be linked with rejection ie being sent to the children’s home if anyone knows date he left home. Or linked in some way with whatever he did that finally led mother to realize she couldn’t manage him?
