Tatarsky was the pen name of Maxim Fomin, who had hundreds of thousand of followers on his Telegram messaging app channel. The FSB claimed that Denysov acted on orders from the Ukrainian security services. Russia’s Federal Security Service, the FSB, charged that a Ukrainian citizen whom it identified as Yuriy Denysov had gathered information about Tatarsky and supplied Trepova with explosives through a courier service. Authorities in Kyiv have not directly responded to the accusation, but an adviser to Ukrainian President Volodymyr Zelenskyy has described the bombing as part of Russia’s internal turmoil. Russian authorities have blamed Ukrainian intelligence agencies for orchestrating the bombing. The judge said that one of those injured in the blast had died, without giving details on whether it was connected to the blast, and adjourned the hearing until Friday. Kasintsev said in court he was willing to plead guilty to a lesser charge of not reporting a crime.
She had stayed in his apartment after the blast, and the authorities have charged him with concealment of a grave crime. Trepova’s 27-year-old acquaintance, Dmitry Kasintsev, is standing trial with her, although he is under house arrest.
