CW says he weighed 248 before he started thrive, or was it when he met SW? Just trying to envision him in his skater clothes, with greased hair. He's not all that tall.
Another thing, he told his dad "I killed her". Then dad says, leading him, you smothered her? You strangled her? CW is not all that decisive in his answer, imo, although the sound was poor. Then CW says I did the same to her, (as she did to the girls), iirc. Then later with the agents, he mumbles about not actually seeing sw's hands, it was from the side. Sounded vague to me. Other than saying "I killed her" to his dad, did he ever just looked at any of the 3 and say I strangled her? Meaning sw.
I thought that 1 segment of the interrogation, after the polygraph was fascinating, where the agents were suggesting there was an accident, or that one of the girls was killed so that the dead one would not have to keep living alone, or that SW did it. It seems like they tried out several permutations, watching closely to see where he would enter the trap. Leaning very heavily on flattery, his being such a good father, keeping them warm, his own father would always love him, etc.
It made me wonder, in their training, if they have suggested techniques tailored to personality types/crimes/age groups. For instance, if I had killed my husband, I don't think that flattery would have swayed me to confess.
