Aldrich Ames – the Central Intelligence Agency (CIA) officer whose nine-year betrayal to the Soviet Union (and later Russia upon dissolution of the Soviet Union) resulted in the deaths of at least 10 intelligence agents and became the agency’s worst security breach – died January 5, 2026, at the Federal Correctional Institution in Cumberland, Maryland. He was 84 and serving a life sentence.
His death, first reported by journalist Sasha Ingber, was confirmed through the Federal Bureau of Prisons database.

From 1985 until his arrest in February 1994, Ames systematically compromised U.S. intelligence operations, turning over to Moscow the names of virtually all Soviet agents working for the CIA and allied services. In exchange, he received more than $1 million in cash with promises of at least another $1 million and property in Russia.
The case exposed catastrophic failures in CIA counterintelligence. Despite the disappearance of Russian agents signaling a mole within the agency, it took years to focus on Ames, even as he drove a Jaguar and purchased a lavish Virginia house with cash on a government salary. More disturbingly, it was later revealed that Ames was allowed to sit on promotion panels for non-official cover officers while under suspicion, with the affected officers never informed of their exposure.
At his April 1994 sentencing, the 52-year-old Ames admitted he had “betrayed a serious trust” but controversially downplayed the impact, calling spy operations “a sideshow.” His plea agreement spared his wife, Rosario, who received a reduced sentence of five years and three months, and was released after four years to return to their son in Colombia.
In total, when Aldrich Ames and his wife, Rosario, were arrested in 1994, they had received around $2.5 million, the most money paid by the Soviet Union or Russia to any American for spying.
