A pair of 15-year-olds from Russia who had gone on the run from their parents, live streamed on social media how they opened fire at a police car and then killed themselves.“Two armed 15-year-old teens barricaded themselves in a house in the Strugy Krasnye settlement. Law-enforcement officers had been negotiating with them for several hours, however, all in vain. Later on the teenagers stopped responding,” the investigators’ statement says.“We had a sleepover at my friend’s place. I wasn’t allowed to go, but I went anyway. They found me at night… It was harsh and it all happened in front of Denis and his mother. I ran away again,” Katerina said on the video.The teens reportedly spent the next three days hiding from the parents at the house where the tragedy occurred on Monday.“I loved all of you. But you didn’t notice how you ruined my mind and my life,” the note says.In another post Katerina elaborated that she wasn’t taken hostage and that suicide was her “conscious choice.”
