A "raid" or other LE presence occurred at TK's Peru house in late November 2021, then a couple of weeks later, LE released the a_shots ask. LE only asked about the "creator" of a_shots, not specifically KAK, who was only later identified as a creator by the media. In the 2020 interview, LE suggested there were two creators of a_shots.
All in all, LE has not identified KAK as a POI, nor anybody else...at least not publicly. But in the cases of DN, PE, and JBC, there was never anything publicly released from LE to link those men to Delphi outside of LE "looking into them" and our own speculations. The same cannot be said for the user of a_shots, whoever he might be, which LE wants tips sent to the A&L tip line.
LE has been relatively quiet. They imposed a media blackout in the end of July 2021, which we easily attached to JBC, because it happened right after his arrest, and they said, "No further comment on Mr. Chadwell or any other suspect will be afforded in the foreseeable future,"...
Could JBC have information on Delphi? Maybe. Was the media pressing LE about JBC because he does seem like a good candidate for BG? Maybe. But this was only a few months before the a_shots ask, too...
