This collection of documents consists primarily of crime scene inspection protocols, maps, and diagrams related to the Volgodonsk apartment bombing on September 16, 1999. The materials detail the damage to residential buildings on Oktyabrskoye Highway (No. 35 and 37) and Gagarina Street (No. 50, 60, 63, 65, 71, and 73), including descriptions of a central crater, soil samples taken for analysis, and structural failures. Forensic investigators and the FSB Investigative Department recorded the locations of fire sources, broken glass distribution, and damaged balcony slabs. The documents include a 2002 motion from lawyer Mikhail Trepashkin addressed to the FSB Investigative Department regarding his representation in the case. While the files focus on the immediate physical aftermath, they are verified by various investigators including Romanovsky, and mention the involvement of several units in the initial response.
