Crime show claims JonBenet Ramsey WAS killed by her 'violent' older brother and her parents covered it up after the siblings 'clashed over a midnight snack of fresh pineapple'

JonBenet Ramsey (far left, and centre with her parents and brother) was killed by her older brother Burke (pictured recently right) 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 in the basement of her family's home in Boulder, Colorado. Now, a team of experts re-examined the evidence in the 20-year-old case in a two-part CBS documentary The Case Of: JonBenet Ramsey, which concluded on Monday night, and presented their hypothesis that Burke struck his sister with a flashlight, killing her, after she came downstairs late at night and grabbed a piece of pineapple from his bowl (inset). In the first part of the documentary, the investigators revealed six extra seconds of audio from a 911 call that appeared to suggest her family were involved. Investigators believe they can hear Mr Ramsey's voice saying 'we're not speaking to you', before Mrs Ramsey allegedly asks: 'What did you do? Help me, Jesus'.
