'For as long as 40 years, officials said, handyman William Charles Thomas stalked and groomed his child victims, raped them, collected articles of clothing as trophies, and sometimes wrote graphic details on pieces of plywood that he used in renovating trailer homes.'

Let's take this back to the most notorious Podesta email.

Pizza = pussy & penis / dick / ass / head. Not 'girl,' not sex organs or orifices in the physical sense. But the engaging with those things i.e. the receiving or the penetrating, usually in a controlling, coercive, or semi-coercive way i.e. with trafficked individuals or prostitutes. If you want to tie it to the pelvic triangle, men have something a pelvic triangle (at least as pubic zone) when seated too (obviously with a penis at bottom of it), and the social media evidence fully confirms pizza does not only relate to females.

Map = mark/stain of semen, blood, menstrual fluid, etc. Given that those in question are into S&M child sex, it probably involves blood. The stain is basically a map of the encounter. It's not just a random codeword choice. (remember the band Sex Stains)

Handkerchief = not entirely certain, but probably just means thing [related to CP / deviant sex].

Black-and-white [handkerchief] means S&M sex w/ minors, as does panda and dominos.

If the thing is related to sex and can easily be mailed, the overwhelming likelihood is that it is some kind of fabric item, i.e. a towel, underwear, shirt, pants, etc. And if it has a map on it, that has mean to a stain or mark of some kind (what else can be on a fabric but a stain or mark), and it's related to S&M sex, then it probably means it has blood. What else could 'seem to be pizza-related' (i.e. possibly but not certainly be pizza-related) but that?

That's what the handkerchief with pizza-related map is. It is a cloth item with blood and/or other fluids on it from an S&M sex session involving children. We know that the realtor does not view it as incriminating evidence, or she would dispose of it and certainly not mail it or send emails about it. The only possibility then is that Podesta might want the item as a memento, and the reason Podesta was asked about it is because it is normal for pedophiles to want these kinds of mementos, as did the above child rapist.

The only difference between William Thomas and Podesta is that the former is a handyman who lives in a trailer park and the latter is among the most connected and influential people in American politics.
