After the sentence is carried out, a prison doctor and other officials certify that the execution has been performed and a death certificate is prepared. The remains of the condemned are buried secretly, and the family is notified that the execution has taken place. Col. Oleg Alkayev, who was a director of SIZO No. 1, claimed that about 130 executions took place at the prison between December 1996 and May 2001, when he left Belarus to live in exile in Berlin, Germany.
