Ollanta Humala sentenced in money laundering case – Nationalist Party
Ollanta Moises Humala Tasso was President of Peru from 2011 to 2016.
Nadine Heredia is in Brazil, a country that granted her diplomatic asylum. Therefore, she could not be apprehended by the police following the sentencing.
Humala returned to prison after eight years, having first been sent to Barbadillo in 2017 to serve a preventive detention order.
The initial measure also applied to his wife, who was held at the Women's Annex Prison in Lima's Chorrillos district. Both were released eight months later, in April 2018.
Years later, the Judiciary ruled in first instance that they were guilty of money laundering and ordered them to be sent back to prison to serve their sentence. Humala has been held at Barbadillo since April 15, 2025.
According to the Prosecutor's Office, both reportedly received illicit funds from contributions to the Nationalist Party made by Brazilian company Odebrecht and the Venezuelan government to finance the 2006 and 2011 political campaigns.
