Three Russian teenagers, who allegedly murdered their father have revealed the reason behind their action.

According to reports , the teenagers, Kristina, 19, Angelina, 18 and Maria, 17, confessed to jointly killing their heroine-addict father, Mikhail Khachaturyan, claiming they suffered years of appalling sexual, physical and emotional abuse.

Kristina told police: “We hated him and we wanted just one thing to happen – either that he disappeared or that we never knew him.

“We wanted him just to go away and never come back.”

The sisters alleged that on the day of the attack he had threatened them with a knife in their flat near the Altufievskoe highway in Moscow.

One of the sisters had grabbed the knife and stabbed him, and the others joined in the attack, say reports.

The man tried to escape the flat but was attacked more and died near the elevator.

Friends and neighbours claimed the father was tyrannical and that his wife, the girls’ mother — left him because of his abuse, while a son, now a student at Moscow University, had been “thrown out” of the home by the father.

Sergei, their brother, reported to be 21, was quoted as saying: “My sisters just could not have done it.

“I don’t know what happened. I don’t know who to believe. I have not lived there since I was 16.

“He forced our mother to leave too but I do not know what for. He wanted me to grow up a strong man.

“If he beat anyone it does not mean he was a bad person.”
