Two sisters whose mother was killed in one of the houses hired Trepashkin to represent them in the trial of two Russian Muslims accused of transporting explosives for the bombings.
Kaks õde, kelle ema ühes plahvatuses hukkus, palkasid Trepaškini end esindama kohtuasjas, milles kahte muslimit süüdistati lõhkeainete transpordis pommiplahvatuste korraldamiseks.
