Murder initially blamed on wife but 3 burned corpses found near Rokhlin's home. FSB General Trofimov and Litvinenko agreed with many of Rokhlin's colleagues that his killing was orchestrated by the FSB and the assassins were subsequently killed. Apparently motivation for Litvinenko & team to whistle blow in 98 when given order to undertake killings - ie they realised if they started down the road of extra-legal killings they would likely become victims themselves.
