The guards apparently thought he was faking, and the psychologist thought he might be faking at times. If I had to lean in a particular direction though, I'd go in the direction that he was in some sort of crisis. He did apparently start talking about God quite a bit before it happened, and in my limited experience seeing that (when it comes out of the blue), what follows is never good. It's of course also possible that he came in and out of that state to some extent.
So at this stage (knowing nothing), I'll give the defense that. It becomes a moot point though if those confessions include real details that only the killer would know though.
This part sounds like the concerns I would expect a lucid person to have:
Allen, Harshman said, talked about why he killed the girls and why he delayed in confessing, although the detective did not elaborate on what those motivations were. Harshman also said Allen expressed fears that his family will no longer love him after the trial, during which they will see graphic photos of the girls' bodies.
Witnesses testified this week about Delphi murder suspect Richard Allen's statements and behavior following his arrest.
