De Jong later had legal proceedings about money laundering of the money he had earned from the drug trade. In 2017, the court convicted De Jong of money laundering, after a lengthy procedure. He was sentenced to six months in prison and his villa was confiscated. In 2018, the Court of Appeal acquitted him of money laundering. However the Public Prosecution Service appealed in cassation and the Supreme Court sent the case back to the Court for a new appeal.
