Blokhin Sergey Nikolaevich.
Blokhin favoured the 7.65 mm Walther PPK pistol,
a gun which was being used for all the mass executions.
Blokhin would work nearly uninterrupted each night,
reportedly killing a prisoner about every three minutes, averaging around 300 executions per night.”.
Blokhin quickly rose through the ranks of Russia's secret police at the time- the NKVD-
eventually becoming the head of the Kommandatura department.
On April 27, 1940, Blokhin was rewarded with the Order of the Red Banner
for carrying out this amazingly bloody organized mass killing.
Blokhin's total of over 7000 executions is a drop
in the bucket of deaths caused by the Stalin regime, estimated between 10 to 20 million!
For Blokhin, it didn't have as much of a kickback as other guns,
which meant less pain in his wrist after performing hundreds of executions every day.
Under the guise of other positions, Vasili Blokhin was officially a commandant of a prison-
the department carried out black work missions specific to furthering Stalin's cause.
Blokhin oversaw many mass executions and executed several high-profile individuals himself,
including Mikhail Tukachevsky, Marshal of the Soviet Union, and two of the former NKVD chiefs under whom he had previously served.
Along with the 7000 prisoners of war Blokhin personally executed at Katyn,
he is reportedly directly responsible for the deaths of many thousands of other people in prison camps during the Second World War, aptly earning him that title of“Most Prolific Executioner” in the Guinness Book of World Records.
