Overview
- A Bureau of Prisons spokesperson said Ames died Monday at FCI Cumberland in Maryland while serving a life term without parole.
- Officials have not released a cause of death, and the medical examiner will make the formal determination.
- Ames sold classified information to the KGB and later Russia from 1985 until his 1994 arrest, receiving about $2.5 million.
- He admitted exposing 10 Russian officials and one East European working for the U.S. or U.K., and officials say his disclosures led to arrests, executions, and the compromise of scores of cases.
- He pleaded guilty to espionage and tax evasion in 1994; his wife, Rosario, also pleaded guilty and served a prison term, and the case spurred later insider‑threat and financial‑monitoring reforms at U.S. intelligence agencies.
