Twenty years after JonBenet Ramsey's murder, her own family members remain among the main suspects.
Burke Ramsey -- who was just nine when his sister was killed -- is finally breaking his silence on allegations he or his late mother, Patsy, were responsible for her death.
JonBenet's brother appeared on "Dr. Phil" on Monday and Tuesday in his first public interview ever ... and TV host definitely didn't hold back. On today's episode, McGraw grilled Burke on the many theories surrounding his sister's murder, starting with his mother's involvement.
One popular theory suggests Patsy killed JonBenet in a fit of rage over wetting the bed, then staged the murder and wrote up the ransom note found inside the house herself.
"Do you know the theories about your mom?" Dr. Phil asked.
"I don't know the details but I know the ransom note, they think the handwriting matched," Burke replied. "I don't think I've read the whole thing, I've definitely seen pictures of it. I've never really looked at it closely, I'll see it and get taken aback and it's not something I really want to look at a lot."
When asked if he thinks the letter looks like it was written by his mother, he responded, "Honestly, I think it's too sloppy."
Ramsey went on to say he never witnessed his mother "fly into a rage," throw anything or use corporal punishment.
"No, we never got spanked, nothing of the sort, not even close," he explained. "Not to say she didn't get upset, [but] nothing near putting a finger on us, let alone killing her child."
The hard-hitting questions kept coming.
Did you hit your sister over the head with a baseball bat or flashlight? "Absolutely not."
Did you have any knowledge or suspicion that JonBenet had been sexually abused or molested in any way? "No."
She never said anything? "Absolutely nothing that would lead me to believe that anybody was sexually abusing her in any way."
Did you ever sexually abuse JonBenet? No. Absolutely not.
In never-before-seen interviews Burke did with police shortly after his sister's murder, he appears calm and, using Dr. Phil's words, "unbothered" by what was happening.
"I can tell you I was very emotional. I would just immediately cry out of nowhere," Burke said of criticism over his demeanor. "It was the combination of getting to know this weird guy I've never talked to before asking all these personal questions. At some point you have to move on... you gotta stop crying at some point I guess."
The episode ended with Phil asking one final question: "Let's clear this up once and for all, did you do anything to harm your sister? Did you murder your sister, JonBebet?"
Naturally, it cut off before Burke was able to answer. We'll find out his response -- which, let's face is, is probably going to be "Absolutely not" -- when Part 3 of Dr. Phil's sit-down airs next Monday.
