Kolpashevsky Yar is a high steep bank of the Ob River in the city of Kolpashevo, Tomsk Region, Russia.
A. Spragovsky, senior investigator of the KGB in the Tomsk Region, who worked in the Tomsk Region in the 1955-1960s and participated in the rehabilitation of the repressed, quotes the testimony of one of the executors of the death sentences in 1937, who showed that next to the building of the Narymsky district department of the NKVD in Kolpashevo “there was a large platform surrounded by a high fence, a pit was dug there, where you could go up on a specially arranged ladder.
At the time of the execution, the performers were in a shelter, and when the arrested man approached a certain place, a shot rang out and he fell into the pit.
Shutov, on a washed bank near the burial ground, a blank fence was installed and a cordon was put out so that people would not bring flowers and candles.
Detachments were formed from employees of the Ministry of Internal Affairs, the KGB, and volunteer squads were created, who were put on motor boats and blocked the river with them.
There it was decided to prevent publicity, with the aim of which it was indicated to destroy the remains and signs of this and other similar Kolpashevsky burials.
At a meeting in Tomsk, they decided to liquidate the grave from the water, to wash away the shore with a stream of motor ship propellers, and the remains of corpses would be sunk in the river.
At the same time, the area of the mass grave was cordoned off by the forces of soldiers of the arrived units of the KGB.
