This document lists investigative questions for the Public Commission examining the 1999 Russian apartment bombings, focusing on the testimony of Achemez Gochiyayev. It scrutinizes the use of a deceased individual's passport, belonging to citizen Laipanov, to rent warehouses on Guryanova Street and Kashirskoye Highway where bombings occurred. The text raises concerns regarding the firm 'Kapstroy-2000,' Gochiyayev's business activities, and his prior detention in Karachay-Cherkessia. It also addresses allegations made by suspects Bachaev and Krymshamkhalov, who reportedly linked FSB Director Nikolai Patrushev and German Ugryumov to the explosions. The document questions the methodology and documentation behind testimonies provided to Yuri Felshtinsky and Alexander Litvinenko.
