Aldrich Ames, the former CIA officer whose historic betrayal compromised more than 100 clandestine operations and led to the execution of at least ten U.S. intelligence sources, has died at the age of 84.
Ames, who was serving a life sentence without parole, died on Monday at the Federal Correctional Institution in Cumberland, Maryland, CBS News reported.
Sentenced on April 28, 1994, he had confessed to selling highly classified information to the Soviet Union and later Russia over nearly a decade.

His espionage, conducted from within the CIA’s own counterintelligence branch, divulged the identities of more than 30 Western agents.
The U.S. Justice Department described his actions as “one of the most devastating spy cases in American history.”
