Did River Song kill the stone Dalek?

That is what we are led to believe. River thought that the Dalek had killed the Doctor, she made the Dalek beg for mercy, and - as Ты quoted - she afterward сказал(-а) that the Dalek died. I suppose it's possible that she didn't kill it, but it is heavily implied that she did.

me:rule one. the doctor lies. and so does river.
maybe........ i dont have an awnser
