The U.S. Department of Justice announced on Thursday that four people were charged in Los Angeles for participating in a scheme to allegedly launder the proceeds of crypto-investment scams.

The DOJ stated that the four opened shell companies and accounts in order to launder over $80 million from victims’ money obtained through fraudulent schemes such as pig butchering.

Scammers who use “pig butchering scams” contact their victims via dating sites or social media to gain their trust, before pitching them a cryptocurrency-based moneymaking opportunity.

They were accused of conspiracy to commit money launder, concealment of money laundering and international laundering.

The DOJ stated that two of the accused, Lu Zhang from Alhambra, Calif., and Justin Walker from Cypress, Calif., could face 20 years of prison if found guilty.
