But haven't witnesses said they didn't see those emotions ....
Witnesses' testimony has differed from what they originally did and did not report, a male witness the State didn't call said RH's pain was so great it made him cry for RH, the common thread in witness accounts is that RH would alternate being screaming oh my God, oh my God, what have I done? I've killed my son (a strange way to phrase things if he murdered Cooper and had staged the scene to avoid accountability) and appearing to be "calm."
One witness said pretrial that she didn't find any of his behavior suspicious, and that it seemed to her that he was processing what had happened. At trial she test testified she thought he was just acting. Go figure.
Same with Leanna. Pretrial the line was she wasn't shocked or emotional, just calmly said, well, Ross must have left him in the car. Nope. Even according to the strange testimony by the HD guard, she was anything but calm,up until the time when she saw the news of her son's death on TV when she went silent. Can't imagine why LE (or the clueless guard) interpreted that as anything other than pure shock.
