Two school girls Yulia Konstantinova, 15, and Veronika Volkova, 16, fell to their deaths on Sunday from the roof of an apartment block in industrial Ust-Ilimsk.
Today a girl named only as Ekaterina, 15, was critically injured after falling onto snowy ground from a flat in the city of Krasnoyarsk, also Siberia.
She did not obey the commands - but there are fears that others did.
In the Chita case, transport police confirmed that the so-called suicide game 'Blue Whale' is seen as a possible 'cause of death'.
E- Commerce, E- Business and E- Marketing are phenomena that appear as the result of the Internet invasion.A second girl had made plans to kill herself with the dead teenager, but changed her mind at the last moment.Teenagers are urged to use a knife or razor to make the shape of a whale on their wrist or leg, say Russian reports.It sounds quite ironic when the lack of face to face communication is mentioned as one of the negative effects of Internet because the Internet is supposed to bring people closer.But the fact is that somehow many people find it easier to communicate through the Internet instead of the traditional direct way.They are also urged to watch horror movies all day, and to wake themselves at 4.20am, steps leading up to demands to take their own lives on the 50th day of being in the game.
