Maria del Rosario Casas Dupuy Ames was the Colombian second wife of Aldrich Ames, a high-ranking official in the U.S. Central Intelligence Agency (CIA) who became a notorious double agent for the Soviet Union and Russia.12

Rosario met Aldrich Ames while he was posted in Mexico City and he recruited her to work for the CIA. They married in 1985, and that same year, Rosario helped Ames begin selling American intelligence to the KGB. By the time they were arrested in 1994, they had received over $2.7 million for their espionage activities, making it the largest sum paid by the Soviet Union or Russia to an American spy. Aldrich Ames was sentenced to life in prison for espionage, while Rosario pleaded guilty to tax evasion and conspiracy to commit espionage, receiving a sentence of 63 months.12
