On May 15, 1925, in the course of government reprisals following the St Nedelya Church assault, Geo Milev, a member of the Bulgarian Communist party, was taken to a police station for a "short interrogation" from which he never returned. His fate remained unknown for 30 years. In 1954 during the trial of General Ivan Valkov and a group of former police and military executioners, one of the defendants confessed how victims of the 1925 purge had been executed and where they were buried. Geo Milev had been strangled with wire and then buried in a mass grave in Ilientsi, near Sofia. His skull was found in the mass grave. His body was identified by the glass eye he was wearing after he lost his right eye in World War I.
