The brutal slaying of adorable six-year-old beauty queen JonBenet Ramsey gripped America as few crimes have ever done.
On the day after Christmas 1996, holiday cheer turned to horrified despair after the tot's father, millionaire executive John Ramsey, discovered her lifeless body in the basement of the family's mansion in Boulder, Colo.
The young beauty had been beaten and strangled. A nylon cord was wrapped around her neck and duct tape covered her mouth. Her wrists were tied together.
A chilling ransom note demanding $118,000 was found on the stairs inside the house.
John and his wife, Patsy, who died in 2006 from ovarian cancer, were shattered by the horrifying crime. And the nation awaited justice for JonBenet.
But to this day, her murder remains unsolved.
The case appeared to be broken wide open in 2006 when twisted teacher John Mark Karr confessed to killing the child. He was later discredited.

But there remains hope.
In 2003, forensic experts managed to draw a DNA sample from a tiny, badly degraded bloodstain on JonBenet's panties.
The DNA is compared on a weekly basis to the biological samples taken from newly arrested men which have entered into the FBI's database. Investigators are hoping one day they will find a match.
