Mark Redwine sat at the edge of his chair like a cat ready to attack his prey, blasting out blame which had no context. "YOU didn't send him with a coat!" "What kind of MOTHER......."
It's almost like he's thinking to a time when Dylan was nine how Dylan "always" watched Nick when he was with him and liked messing around at the rock retaining wall, bridge, and campground.
And then he showed his sense of inadequacy about Elaine having a real job - like he did when dissing Elaine about her career in an earlier interview - with his lame attempt to dirty-up her "professional" life with hanging out with criminals.
Mark reverted into his bs-ing mode with Dr. Phil - then anger and blame took over when talking directly to Elaine.
Oh this must be so difficult and painful for all. I feel this Dr. Phil effort will help solve this case and justice will be served.
Just my opinion.
