Gennady Lopyrev, a former lieutenant general in the Russian Federal Protection Service (FSO), who was serving a sentence for bribery in a penal colony in Ryazan Oblast, Russia, died on August 16. The chairman of the Public Monitoring Commission of Ryazan Oblast, Viktor Boborykin, did not provide the cause of Lopyrev’s death, but a Russian insider source claimed that Lopyrev was “unexpectedly” diagnosed with leukemia on August 14 after suddenly complaining of shortness of breath despite normal health indicators. The insider source claimed Lopyrev was “the keeper of secrets” related to the construction of Russian President Vladimir Putin’s Black Sea residence in Gelendzhik, often referred to as “Putin’s Palace.”
