The head of the control and auditing service of the Moscow mayor's office, Andrei Shilov, was killed along with his entire family - his wife Anna and son Dima. The investigation did not immediately sweep aside the version that Andrei killed his relatives himself, because his wife convicted him of treason and was clearly not going to let him get away with it. But soon there was information that Shilov had found serious violations in the activities of one of the private security companies that ensure the safety of schools.
