He is mentioned a few times in "A Feast for Crows" (2005), because stories are spreading that somebody using the Hound's helmet is committing atrocities. But the Elder Brother mentions to Brienne of Tarth that he found Sandor , and is now "at rest", so his helmet was doubtless stolen from his graveyard. However, the appearance of a mute gravedigger who matches Sandor physically and the Elder Brother's refusal to confirm if Sandor is dead imply that he may still be alive.
