Sandra “Sandy” Grimes, the former CIA officer best known for helping expose Soviet mole Aldrich Ames, has died at the age of 80. Her passing was announced by a family member in a Facebook post. Grimes was a central figure in one of the most damaging spy cases in U.S. intelligence history. As part of a small CIA-FBI task force, she helped uncover Aldrich Ames, a longtime counterintelligence officer who was secretly working for the Soviet Union. The investigation culminated in Ames’ arrest in 1994, after he had compromised numerous American assets overseas.
