They got Al Capone on tax evasion....
If this fat Kat whatever his name is, is involved in PedoPizza stuff, LE took boxes of stuff from his home, and no doubt from the three pizza parlors. IMHO, if he is PedoPizza connected (and I have a hunch he is), they are going through all kinds of stuff for evidence, and the financial stuff was the prybar, and to avoid saying anything publicly that they didn’t have to.
I have a hunch he is not peso-connected since he would have been arrested and charged pretty much right away. They investigate quickly and charge. If he is not charge for child porn or similar within a week or two, then it was the same reddit thread stuff that has made up most of pizza gate.
