Sometimes it could be to fish out more info of other high position ppl involving so take a while I think. I do not think only he one person involved there must be others in a group format. Only group format can do wonderful stuff. One chopstick easy to break but if a bunch of chopsticks very hard to break. So investigators should be seeking to break the bunch of chopsticks not easy feat.

You mean release long string to catch bigger fishes? .....
