"any concrete evidence of CIA complicity in the Younis killing?"

The short answer, which should not be surprising, is "No!" I have no contacts within the CIA and they haven't admitted any complicity publicly.

General Khalifa Haftr has been linked by some bloggers to the CIA but evidently only because his home in exile in Fairfax, Virginia, is within five miles of CIA headquarters. And no one I'm aware of has suggested that Haftr was directly involved in the assassination of General Younes, but Haftr is logically the Rebel general who will benefit the most from his death. Connecting the dots as I've been doing is not conclusive proof of anything but does raise a question that I think merits further research.
