"The prosecutor's office approved the indictment - the murder of a group of persons by prior conspiracy," RIA Novosti quoted Parshin as saying.
He said that the case should now be referred to court.
However, he said that "the case of the youngest of the sisters will be considered separately."
“In the case of the other two, we have filed a motion for trial by jury,” the lawyer said.
He suggested that "most likely, the process will be closed, since there is evidence of violation of sexual integrity in the case."
Earlier, the Investigative Committee of Russia completed an additional criminal investigation into the killing of his father by the sisters Khachaturian.
The ministry said that "at present the criminal case against Krestina and Angelina Khachaturian has been sent to the prosecutor with an indictment, and against Maria Khachaturian - with a decision on the use of a coercive medical measure."
On July 27, 2018, the body of Mikhail Khachaturian with multiple stab wounds was found in a house on Altufevskoye Shosse. In August 2018, the Khachaturian sisters pleaded guilty to the murder of their father and gave detailed evidence in the framework of this case.
