From this interview with the International Affairs Forum:
IA-Forum: [Would] you please comment on the recent murder of Natalia Estemirova?
Mr. Satter: This is part of a whole string: Stanislav Markelov, Anna Politkovskaya… One of the signs of the cruelty or the lack of morality of the Putin regime is the fact that their protégé, Kadyrov, is really absolutely free to murder anyone he wants to, to torture, to kidnap with complete impunity; whether it’s in Chechnya, whether it’s in Russia, whether it’s in Vienna; as long as he keeps the situation under control for the leadership in Chechnya. This was a woman who was monitoring the human rights situation in Chechnya. She was a colleague of Markelov, who was a colleague of Politkovskaya. So who’s behind it? We know that Kadyrov said the people who are disappearing are being murdered. These are people who are his opponents and enemies.
And don’t expect any serious effort to investigate. When Markelov was killed along with Anastasia Barburova—in broad daylight near the Christ the Savior church on a crowded street—no one thought it worthy of comment until nine days later when Medvedev did an interview with Novaya Gazeta and said something. This shows the character of the regime. Bearing that in mind, an American president should not bend over backwards to praise Putin and to praise the Russian leaders. They are not deserving of that.
