Nikolayev's mother, brother, sisters and cousin, and some other people close to him, were arrested and later killed or sent to labour camps. Arrested immediately after the assassination, Nikolayev's wife, Milda Draule, survived her husband by three months before being executed as well, while their infant son Marx (named following the Bolshevik naming fashion) was sent into an orphanage. Marx Draule was alive in 2005 when he was officially rehabilitated as a victim of political repressions, and Milda was also found innocent retrospectively. However, Nikolayev was never posthumously acquitted. Several NKVD officers from the Leningrad branch were convicted of negligence for not adequately protecting Kirov, and sentenced to prison terms of up to ten years. According to Barmine, none of the NKVD officers were executed in the aftermath, and none actually served time in prison. Instead, they were transferred to executive posts in Stalin's Gulag labour camps for a period of time, in effect, a demotion. According to Nikita Khrushchev, the same NKVD officers were later shot in 1937. Lajos Magyar, a Hungarian communist and refugee from the fall of the Hungarian Soviet Republic of 1919, was falsely accused of complicity in Kirov's assassination. Magyar was convicted as a "Zinovievite-Terrorist" and sent to a Gulag, where he died in 1940.
