Krymshamkhalov wrote to Novaya Gazeta that Ugryumov arranged the bombings. Grigory Pasko, ex-Navy human rights & environmental journalist, wrote that Ugryumov had probably been murdered, a version corroborated by anonymous FSB whistle-blowers. A widely circulated but unverified comment on a blog states that Ruslan Saidov quoted Ugryumov as saying: "We had to blow up buildings to get him into the Kremlin. How much blood will it take to remove him?" This is the profile page for Saidov: http://www.pravo.mgimo.ru/?q=node/11181
