Let's work on some hypothesis material.
If PR is, 'our man', and there is a scientific foundation in his, 'gaining ground', in his escalation of crimes... Stay with me here. Would there not be much much more at his previous residences? I may have bombed the wording in that.
If this is next, 'level', in his escalation.... After all of the charged crimes he now faces, would our dear Libby be possibly his worst perversion?
I mean, did your Police check for DNA in her home? Her drawers, in her drawers? Ugh. I had to write that. Ugh. The bathrooms? Her flatmates? How many? Did they thoroughly check that entire house?
Because if they didn't, I have a sneaky feeling this could end bad. Heavens, I want Lilly to be safe as much as all of you. But if they are 100% sure it's him, they may be overlooking evidence. IMO I may be a little off my rocker, on this one...
