This collection of documents details the legal proceedings and investigations surrounding Yusuf Ibragimovich Krymshamkhalov following his 2002 extradition from Georgia for his role in the 1999 apartment bombings. It includes prosecutorial petitions for the extension of his detention, medical and psychiatric assessments from the V.P. Serbsky State Scientific Center, and extensive victim lists detailing the injuries sustained in the Volgodonsk bombing. In his interrogations, Krymshamkhalov denies involvement in the Moscow bombings (Guryanova St. and Kashirskoye Highway) and claims he believed the explosives being manufactured in the settlement of Mirny were merely 'dry paint.' He admits to participation in the Volgodonsk bombing but asserts he did not activate the device. The documents implicate several key figures including Arab mercenary leaders Emir Al-Khattab and Abu Umar, as well as suspects A.Sh. Gochiyayev, A.O. Dekkushev, and T.A. Batchayev. Notably, Krymshamkhalov mentions being interviewed by a figure he later associated with Yuri Felshtinsky while in the Pankisi Gorge.
