A former client of the law firm at the center of the Panama Papers scandal pleaded guilty to crimes related to an alleged criminal scheme involving the Panama-based global law firm Mossack Fonseca for nearly 40 years.

Harald Joachim von der Goltz, a German who is a former U.S. resident, pleaded guilty in Manhattan federal court to charges of conspiracy to commit tax evasion, money laundering, and wire fraud, the Justice Department announced on Tuesday. The 82-year-old faces up to 15 years in prison and a fine of up to $350,000. He is the first person to plead guilty in the United States to crimes stemming from the Panama Papers investigation.
