Where will Robert Hanssen be buried? Burial site and Find a Grave details

Hanssen, 79, was discovered lifeless on Monday morning, his demise marking the end of a dark chapter in U.S. intelligence history.

Sentenced to life in prison in 2002(two decades ago ) for espionage, Hanssen was responsible for one of the most damaging breaches of national security, leaking classified information to Russian intelligence.

Hanssen will be laid to rest at a yet-to-be-disclosed burial site, where his final resting place will be marked on Find a Grave, a platform dedicated to memorializing the deceased.
