An inhabitant has been killed in Knavesville and the Sheriff has interrogated four suspects. It is known that one of them is the killer. As is expected of Knaves, they alternated between telling the truth and lying (Not necessarily in that order).

Each suspect was first asked if he was the killer, to which the sheriff got the same answer from all the four suspects.

He then asked them, 'Who was the killer?' The answers to which are shown below.

Abbey said: Bart is the killer.
Bart said: Dean is the killer.
Cody said: Bart is lying when he says Dean is the killer.
Dean said: If Abbey did not kill him, then Bart did.

Who was the killer?

yeah, but the sheriff knows it is knavesville... he knows that people tell lie, tell truth, tell lie, tell truth... :) when one lives in cities like knavesville, one must ask at least two questions everytime... :) :)
