This document consists of analytical reports and investigative journalism segments concerning the September 1999 apartment bombings in Moscow and Volgodonsk. It provides a technical analysis of the detonators and circuit closers used, suggesting they required professional soldering and were built for reliability rather than mere intimidation. Significant focus is placed on the Kovalev Commission's efforts to investigate the bombings, including allegations that Nina Epifanova of the 2nd REU section rented the Kashirskoye Highway basement to the terrorists while misleading police officer Dmitry Kuzovov. The text also explores the 'Lazovsky gang' and its alleged connections to FSB General Khokholkov, SVR Colonel Suslov, and Chechen figure Khozh-Ahmed Nukhaev. It tracks the movements and claims of Achemez Gochiyayev, who alleged he was 'used blindly' by an FSB agent, and notes Anatoly Mylnikov's accurate early warnings of the bombings to Russian media. Additionally, the document mentions the suppression of investigations and the suspicious 'foreknowledge' of the Volgodonsk bombing by Duma Chairman Seleznyov.
