It actually goes like this

Touka (referred to as Rabbit) was the one who killed Kureo. Ken (Eyepatch) was said to have been involved in it in someway but Amon was the one fighting him. To this date (in the manga) Akira believes the Rabbit is responsible and in :re Ayato is the referred to as Rabbit\Black Rabbit so I take it he's taking the blame for his sister in some sense.

In the ANIME, however, while it was indeed Touka who still killed Kureo, Ken took the blame for it, however only Amon knows that Ken didn't do it. The entire CCG (besides Amon) believes that Eyepatch was the one who killed Mado, this coupled with Ken's involvement with Aogari has led the CCG to believe he's pretty dangerous
