(CNN) — One of the most notorious spies in United States history, responsible for the arrest and eventual execution of numerous Soviet and Russian officials secretly working on behalf of the US intelligence community, has died at the age of 84.
Aldrich Ames, a former CIA case officer arrested by the FBI in 1994 and sentenced to life in prison for espionage, died in custody on Monday, according to a spokesperson for the US Bureau of Prisons.
The official said a Maryland medical examiner will determine his cause of death.

“Not only were the CIA and its intelligence sources in the Soviet Union completely compromised, he also was in a compromised position,” said Bianna Golodryga, CNN anchor and senior global affairs analyst.
In the aftermath of Ames’ arrest, congressional investigators slammed the agency for its inability to deal with Ames’ suitability problems, including “drunkenness, disregard for security regulations, and sloppiness towards administrative requirements.”
“The Ames case reveals glaring weaknesses in the CIA’s procedures for dealing with the career assignments of employees who are under suspicion for compromising intelligence operations,” the Senate Select Committee on Intelligence wrote in its 1994 report.
