Analysis of information sources in references of the Wikipedia article "Биценко, Анастасия Алексеевна" in Russian language version.
The Moscovites had a woman as a delegate - of course simply for propaganda reasons. She had shot a Governor who had been unpopular among the Leftists, and was not sentenced to death but to life-long imprisonment due to the mild Tsarist practise. This person, who looked like an elderly housekeeper, Madame Bizenko, apparently a simple-minded fanatic, detailed to Prince Leopold of Bavaria who sat next to her at the dinner table how she conducted the assault. She demonstrated with the menu card in her left hand how she handed a petition to the General Governor— "he was an evil man," she explained—and shot him from beneath the petition with a revolver in her right hand. Prince Leopold listened in a friendly way, as if vividly interested in the murderer's story. Haffner, Sebastian.
