Two former top South American Football executives have been found guilty of multiple charges at a US trial into corruption in the sport.
The men were arrested in 2015.
The jury in New York are still deciding the verdict in a charge against the former head of Peru's federation.
They will reconvene after Christmas to make a decision in the racketeering charge against Manuel Burga.
His lawyer declined to make a comment on the Reuters news agency.
Marin, who is also a former governor of São Paulo, was found guilty of six of the seven counts against him of money laundering and wire fraud conspiracy.
Napout, who headed the Paraguayan football body as well as the regional one, was found guilty of three charges - one of racketeering conspiracy and two wire fraud charges.
The investigation focuses on corruption around the awarding of media and marketing rights for major sporting competitions, including the Copa America. Prosecutors have said the crimes amount to an estimated $200m (£150m).
