Questions mount over JonBenet murder confession

Thai authorities today barred access to murder suspect John Mark Karr as varying accounts of what he said about the death of six-year-old JonBenet Ramsey raised questions as to whether his confession could help solve the decade-old case.

Karr, 41, was taken into custody at the request of US officials on Wednesday pending his extradition to Colorado in the United States, where he will face charges of first-degree murder, kidnapping and child sexual assault.
