Prosecutors say Mexican-based brokers oversaw a network of “money movers” who transported drug proceeds throughout the U.S. and deposited it into so-called funnel bank accounts. From there the funds were wired to accounts in Mexico.

Authorities say 75 people are charged in the U.S., with some accused of drug distribution.
