Shocking new revelations have come to light in documentary 'The Killing of JonBenét: The Truth Uncovered' which aired on Monday.
The show included never-seen-before footage and documents from the unsolved December 1996 murder of six-year-old pageant star JonBenét Ramsey, which has captivated the public for almost 20 years.
For the first time viewers saw footage of the victim's brother, Burke Ramsey, being interviewed by police interviews in 1996 and 1998, when he was just 9 and 12.
In the interview a nervous Burke recalls the last time he saw his sister and answers simple questions about his sister's death and specifically about Christmas Day, the last time she was seen alive.
When is the last time you saw JonBenet alive?' the police investigator asks Burke in one clip.
Kneeling on his chair, Burke bites his bottom lip before responding: 'Um....probably...in the car...tired and laying down.'
In another segment of his interview, Burke is asked about Christmas morning, some 24 hours before his sister was first noticed missing.
According to Burke, JonBenet and the rest of his family were just as happy and excited as usual.
'What do you remember about that morning and about the fun things you were doing that day?' the investigator asks.
'I just remember her falling on the bike and sitting on it,' Burke responds.
'Your family, do they take a lot of pictures, as you're opening presents and stuff?' the investigator continues.
'Yeah, we take it in turns, opening presents. Towards the end,we just kind of go for it,' Burke says.
Burke was once a dark horse suspect in his sister's murder, but police have since ruled out both him and his parents as suspects in the case thanks to DNA evidence.
Burke himself did not address the claims in the A&E special, but he is set to give his first television interview with US TV host Dr Phil later this month.
JonBenét's father also sat down for an interview with A&E, again proclaiming his innocence.
For years, JonBenét's parents Patsy and John were the subject of public suspicion about the case, but police have since cleared their names
JonBenét Ramsey was six years old on December 26, 1996, when she was found strangled to death in her basement in Boulder, Colorado
Experts who spoke with A&E said they believed an intruder was to blame
Speaking about the old claims against his son, John Ramsey said: 'The accusation that Burke is some violent 90-pound, 9-year-old-child … is laughable. I’m sorry — I can’t think of a better word.
Experts who spoke with A&E largely agreed with Mr Ramsey, saying that DNA evidence suggested that the six-year-old pageant queen's killer was actually an intruder.
The pretty blonde was first reported missing the morning after Christmas Day, when her parents discovered a ransom note in their house. Their six-year-old daughter was found hours later, in the basement of the home, strangled to death.
No one has ever been charged with her murder, but Boulder Police say that the investigation remains open.
