 In June 1918, Beloborodov approved an initiative by the regional Cheka led by Gavril Myasnikov to murder Grand Duke Michael, either in advance, or after the fact.It was under Beloborodov's administration that the former Emperor Nicholas II, his wife, their five children, and a number of their former retainers were transferred to Yekaterinburg, though it was Bolshevik War Commissar Filipp Goloshchyokin who was in overall charge of the family's incarceration, while Yakov Yurovsky was appointed as commandant of the Ipatiev House, and Pavel Medvedev headed the external guard.Along with Pyotr Voykov, Beloborodov directed the smuggling of letters written in French to the imprisoned Romanovs at the Ipatiev House, claiming to be a monarchist officer seeking to rescue them, composed at the behest of the Cheka.
