The appearance of Gochiyayev and his testimony could have interfered with the smoothly established version of the investigation, which was not entirely correct.
Furthermore, the appearance of a living Gochiyayev would have forced the investigation to seek out the true organizers of the bombings, which the FSB of the RF clearly did not want.
The FSB of the RF clearly approved a plan:
To sentence the detained minor accomplices, who knew little, to long terms and hide them far away in prison camps.
To physically eliminate Gochiyayev.
After this, the case could be declared fully solved, the participants and organizers (Gochiyayev) punished, and the case consigned to the archives.
This is the typical approach of V.V. Putin and I.P. Patrushev to all major terrorist acts in Russia.
Therefore, we do not know the truth, the full picture of the terrorist attacks, or the real organizers.
If Putin remains President of Russia for another 4 years and continues to deal with the "security" of the state and citizens together with Patrushev and his team, then we will never know the truth.
More likely, conditions will be created such that we will no longer care about the 1999 bombings, as new and more actions will be organized so that everything dissolves and is lost in their mass scale, for it will become impossible to control everything.
Personal Experience and Obstruction
As a lawyer and representative of the victims in the criminal case of E.A. Morozova and T.A. Morozova (who lived in apt. 100 on Guryanova St. in Moscow), I was crudely and illegally denied access to the case materials and the criminal trial in court, so that I could not (taking into account my experience in investigative work) track down the true organizers of the bombing.
In order to remove me from participation in the process, FSB RF officers fabricated a criminal case against me based on clearly contrived charges that do not hold up to any legal concepts.
In the process, cartridges (registered to the FSB RF and FSNP RF) were first planted in my apartment, and when the case of Krymshamkhalov and Dekkushev was transferred to court, a pistol with cartridges (in a small bag) was publicly thrown into the interior of my car, and I was arrested.
