But at least BR had a chance of getting the cash back, as there were no doubts that it existed, merely where the robbers had moved it to.
In this case it seems there never was any cash!
The only chance is to go after the P&Ders for their profits, but will be difficult to:
a. prove they got them dishonestly
b. find where they are
c. find where they transferred their profits to
d. find a court wioth relevant jursdiction
e. get a court order for restitution
f. get the scammers to comply with the order
with Buchler at the helm there is a chance, but it is slim at best.
