It was in a post that said "it sounded like .. " because of the description of the scene. ( not fact exactly , just someone's impression) from the way the scene was described.)Where did you see torture mentioned and the Dad not being with the other 3? I thought during the PC the chief said they were all found in the basement.
About the dad being in a different spot< I agree with the 2 posts above. Id have to listen again, to remember what gave me the impression he was not with them, but as they have said above in @realanastasia and @Snoopster posts could mean he was 2 feet away. ? (I think when they said the Mom was downstairs and couldnt say where dad was, made me jump the gun a little)
