CASINOS, jewellery and underground banks were just some of the means drugs boss Law Kin-man used to launder the millions generated by the heroin smuggling syndicate.
The marathon nine-month trial threw open the accounts of the largest money laundering operation uncovered by police.
It took a 30-strong team of financial investigators a year to plot the numerous trails of cash.
The 30,000 exhibits included six 2.5-metre flow charts detailing a complex web of thousands of transactions through a maze of bogus accounts.
New York accomplice Yuen Ho-yin told how the proceeds were initially laundered via Hong Kong accounts in the names of syndicate members' relatives.
But as the operation's success grew it became difficult to dispose of such vast sums - most of them US$10 and US$20 notes.
