Yuri Dmitriev, 2018 The historian of Stalin's repressions, the former head of the Karelian "Memorial" Yuri Dmitriev is celebrating his 70th birthday in a maximum security colony. He has been in prison for nine years and is “very tired” of being in prison, say his friends who maintain contact with him. Yuri Alekseevich dreams of getting “exchanged”, but the article under which he was imprisoned makes this prospect very difficult.
