JonBenet Ramsey was killed by her older brother Burke and it was covered up by her parents after a fight over a midnight snack of pineapples, investigators have claimed.
The six-year-old's mother Patsy Ramsey called 911 on December 26, 1996 to report that her six-year-old daughter had been kidnapped from her family's home in Boulder, Colorado.
JonBenet, a child beauty queen, was found beaten and strangled on the floor of the family's cellar several hours after the 911 call.
No charges have ever been filed in her murder - and Burke Ramsey and his parents have always denied any involvement in JonBenet's death.
But a team of experts re-examined evidence in the 20-year-old case in a two-part CBS documentary The Case Of: JonBenet Ramsey, which concluded last night.
The team presented their conclusions in the final minutes of the program, saying the evidence points to Burke Ramsey, who was nine at the time.
However, they do not believe that it was a case of murder and said it could have been accidental.
They also revealed that Burke had struck his little sister with a golf club after 'losing his temper' and left her with a scar on her face a year before her death.
James Kolar, the former chief investigation for the District Attorney in Boulder, presented the theory that all the other experts agreed with.
He posited that Patsy had left Burke with a bowl of pineapple and some tea and that when JonBenet had attempted to sneak some of the fruit later, it prompted Burke to lash out and strike her with a flashlight, killing her.[DailyMail]
