Colorado ? Prosecutors cleared JonBenet Ramsey’s parents and brother Wednesday in the 1996 killing of the 6-year-old beauty queen, saying they were “deeply sorry” for putting the family under a cloud of suspicion that hung heavy for more than a decade.

New DNA tests, which focus on skin cells left behind from a mere touch, point to a mysterious outsider. They came too late to clear the name of JonBenet’s mother, Patsy, who died of cancer in 2006.

“To the extent that we may have contributed in any way to the public perception that you might have been involved in this crime, I am deeply sorry,” Boulder County District Attorney Mary Lacy wrote in a letter to the little girl’s father, John Ramsey. “No innocent person should have to endure such an extensive trial in the court of public opinion.”

Lacy said new “touch DNA” tests on skin cells that were left behind on JonBenet’s long underwear point to an “unexplained third party” and not a member of the family.
