When investigators looked closer at the bank, they realized Sze wasn’t the only criminal who’d made TD their depository of choice. There was the group from Manhattan’s Diamond District using bogus gold sales to launder money. The Colombian drug traffickers using TD debit cards to bring their US profits back home. And the human trafficking ring that claimed to be an HVAC company when it opened an account. The more investigators looked at TD, the more money laundering they found.
