Aldrich Ames, CIA officer convicted of spying for Russia, dies at age 84

Aldrich Ames, a counterintelligence officer for the CIA who spied for the Soviet Union and later Russia, has died, according to a Bureau of Prisons spokesperson.

Ames, who was serving a life sentence without the possibility of parole, died Monday at the age of 84 at the Federal Correctional Institution in Cumberland, Maryland.

The 31-year veteran of the CIA is believed to have compromised more than 100 intelligence operations and sent a number of Soviet agents to their deaths or prison, as he traded information for large sums of money that funded his lavish lifestyle.

In pleading guilty, Ames admitted that he compromised “virtually all Soviet agents of the CIA and other American and foreign services known to me” as well as giving the Soviet Union and Russia a “huge quantity of information on United States foreign, defense and security policies.” Ames divulged the identities of 10 agents, and at least nine of them were executed, according to the Defense Department.
