This document is a statement by the Moscow Group for the Investigation of the Events of September 1999 regarding the arrest of Mikhail Trepashkin, a former FSB investigator turned lawyer. Trepashkin was detained on October 22, 2003, on weapon possession charges that the document alleges were falsified to prevent his participation in the upcoming trial for the 1999 apartment bombings. The authors, Lyudmila Evstifeeva and Evgeniy Frumkin, claim Trepashkin discovered evidence of FSB involvement, including an anonymous prediction from the FSB about the mining of three specific houses in Moscow. The document also alleges a connection between the suspect Gochiyayev's business and an FSB-linked criminal group, as previously reported by the late Yuri Shchekochikhin. It further notes the use of hexogen trace allegations against an Ingush man as an example of investigative manipulation.
