This collection of research notes and correspondence details the investigation into the 1999 apartment bombings in Moscow and Volgodonsk, with a heavy focus on the legal proceedings against suspects Adam Dekkushev and Yusuf Krymshamkhalov. The document features technical calculations regarding six tons of hexogen and TNT equivalents used in the attacks, while comparing the findings to the Ryazan 'training exercise' incident of September 25, 1999. It includes a 2002 letter from the General Prosecutor's Office to the Morozov family and references to Boris Berezovsky's allegations that the FSB, not Chechen militants, orchestrated the bombings. Key figures appearing in the notes include investigator Yuri Shchekochikhin, researcher Yuri Felshtinsky, and Alexander Litvinenko, alongside mentions of the 'Kovalev commission' and the role of Shamil Basaev as the alleged mastermind.
