MOO The KAK speculation has been ongoing for years, it's been almost 6 years since his catfishing was discovered and he has been in jail for 2.5 years. Many thought he or his father was BG, there are countless theories on his level of involvement. Now the last hope of KAK being involved is resting on this vague reason given by the prosecution, which is just a part of the asking for the sealing. In my opinion, neither the prosecution or LE has suggested, since RA's arrest, that KAK is involved. As DC said, "We have our man".
A valid reason would be other "suspects" that they are actually working on. And the prosecutor/judge would know if that was true or not, I hope. But the reason given is "there could be others involved", not suspects. Do they want it sealed until the calls to the tip line stop? MOO
