This collection of legal and investigative documents details the procedural history and forensic findings regarding the 1999 apartment bombings in Moscow and Volgodonsk. Senior Investigator I.I. Zipunnikov and Deputy Prosecutors General V.V. Kolmogorov and Yu.S. Biryukov oversaw the extension of the preliminary investigation into 2003, specifically focusing on the accused Adam Dekkushev and Yusuf Krymshamkhalov. The documents confirm that the explosives used were a mixture of TNT, hexogen (RDX), aluminum powder, and ammonium nitrate, often transported in sugar bags. Significant attention is given to the Volgodonsk bombing, where a GAZ-53 vehicle belonging to Abbaskuli Iskenderov was used 'blindly' to deliver the device. The narrative tracks the extradition of Dekkushev from Georgia in 2002 and identifies key organizers as Emir Ibn al-Khattab and Abu al-Walid, alongside perpetrators like A.Sh. Gochiyayev and D.F. Saitakov.
