It took a mere seven years for the Boulder law enforcement community to send the FBI the DNA sample that was found in JonBenet's underpants. It was determined a long time ago that this DNA sample did not belong to anyone in the Ramsey family.
If that's true, then they deserve a degree of contempt. But does that DNA prove that the family had nothing to do with the crime?
