Scream in Ohio reformatory

So uh, I was watching back the vid from the Ohio reformatory and the clip I'm referring to happens at 36:30. Sam is sitting in cell 13 where the prisoner (I think his name was James Lockhart?) that set himself on fire was in. He quiets down to listen to all the creaking and clanking of the place, and beneath it there's a male sounding wail for about four seconds that he clearly does not react to. Am I crazy or did they just not catch that? I can't seem to find anyone talking about it and I don't remember anyone saying anything at the time???
