Investigations are on its way in Russia on three sisters who killed their ‘rapist’ father despite him sexually abusing and torturing them must stand trial for his premeditated murder.

The three sisters killed the father who is also a mafia boss Mikhail Khachaturyan, 57, as self-defence following years of horrific abuse and bullying.

The “tyrant” was killed with his own hunting knife and a hammer by Krestina, Angelina and Maria Khachaturyan – then aged 19, 18 and 17 – two years ago, say investigators.

Reports indicate that Maria stabbed him, and Angelina hit him with a hammer.

The two elder sisters could face up to 20 years in jail following the the committee’s decision.

The Russian prosecutor general will now make a final decision on the charges they will face in court.
