A report was released on the same day as Estemirova's killing, which calls for Russian officials, including Prime Minister Putin, to be held accountable for crimes while they have been in office.
Estemirova's death is the latest in an increasing list of reporters, lawyers and activits who have been killed in Russia, according to Amnesty International.
Who benefits from such a high-profile assassination? Who WANTS to make the Russian leadership look bad right now? (Hint: Who is still pissed off about Putin's removal of the oligarchs who were bleeding the new Russian Republic dry?)
