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.
