I didnt read into this anything about him being suspicious of stinger necessarily.
Rather I read it as "this happened and is as far as I can track it so far".
It's entirely possible he was just laying out the facts and asking for help from there.
It's also possible stinger just thought he was doing a transfer like normal and had no awareness something was wrong with the source of the funds.

This sucks OP. Good luck. Hit the dataminers up for any help tracking down possible chip dumps.
