Later in his career, he was a leader in different Gulag forced labor camps, named by Alexsandr Solzhenitsyn as one of "the main henchmen of Stalin and Yagoda, the main overseers of the Belomor, six hired killers" responsible for the deaths of tens of thousands of people in the construction of the White Sea–Baltic Canal. He was executed during the Great Purge in 1937.
