At JonBenet's funeral, Burke showed no signs of distress or sadness. He did not cry, did not look visibly sad, or anything appropriate to a funeral. You can see clips of his behavior on Youtube. Before her casket was lowered into the ground, he left off what he was doing with his friend, went over to her casket, patted it a couple of times, and then went off with his friend, skipping through the cemetery. He was largely untroubled by what had just taken place.
Which then begs the question...Since according to his parents, he'd been asleep the entire night and never woke up, before they woke him up to go with Fleet White, and did not display ANY emotions appropriate to the violent murder of his only full sibling, WHY DID HE NEED THERAPY for 2 years or so after the murder??? What were they treating???
