Rumour has it it was dodgey diamonds to his India companysPredictable, after the judge's summing up.
Also, there was no money to show that it had ever happened, so he either blew it all of it's still hidden.
Or it never happened. Given the paucity of actual evidence that he'd cheated, the jury went with the obvious choice.
Rumour gets no verdicts.
Also, whatever he did or didn't do, I find it hard to believe he'd be working as a labourer in Auckland (which he was) if he had money salted away somewhere.
