On July 27, the girls, who are now 17, 18 and 19 years old, allegedly killed their father, stabbing him with a knife at least 35 times. The sisters are now facing charges for murdering their father.
According to reports, their father had allegedly systematically abused and beaten them, practically forcing them to abandon their studies due to their bruises and injuries. Moreover, neighbors suspect that the man had been involved in criminal activity.
Earlier, Russian human rights NGO Ivan Melnikov said that the man had an arsenal of weapons, including a shotgun, pistols, knives and a baseball bat. He also had fake FSB documents.
