“During the preliminary investigation, the fact of sexual violence against children was also established, in connection with which a criminal case was opened,” Petrenko quotes RIA Novosti.

Earlier, the chairman of the Investigative Committee, Alexander Bastrykin, instructed to report to the central office of the Investigative Committee on the investigation into the murder of two sisters in Rybinsk.

Their mother's roommate is suspected of a crime.

After finding the bodies of the girls, he disappeared.

They are currently looking for him.

The bodies of children of eight and 13 years old were discovered by their mother, after returning home from work.
