About this sound
This 19-second Russian voice clip delivers a firm denial in which the speaker insists he is not Chikatilo and asks listeners to stop bringing the name up to him. The blunt, fed-up delivery makes it feel defensive and awkwardly funny, like a protest that only makes the accusation stick harder.
