This collection of investigative documents and interrogation protocols details the legal proceedings against Adam Dekkushev and Yusuf Krymshamkhalov for the 1999 apartment bombings in Moscow and Volgodonsk. The materials outline the logistical operations of an organized group led by Emir Al-Khattab and Abu Umar, who manufactured over 14 tons of explosives in Stavropol Krai before transporting them to Borisovskie Prudy, Guryanova Street, and Volgodonsk. Dekkushev’s interrogations reveal the structure of the 'Kavkaz' training camp near Serzhen-Yurt and the roles of specialists like Abu Bakr, a radio engineer who reportedly designed the Casio watch-based timers used in the devices. The documents provide exhaustive lists of casualties and medical findings from the Kashirskoye Highway and Volgodonsk sites, specifically naming victims and documenting the severe explosive trauma suffered. Achimez Gochiyayev is noted for using a forged passport under the name Laipanov to rent storage spaces in Moscow. While focusing on the perpetrators' training in Chechnya and Georgia, the file also includes formal court resolutions for extending Dekkushev's detention through 2003.
