The Boulder Police Department in Colorado has disputed a claim made by a convicted sex offender who confessed to killing JonBenet Ramsey more than 20 years ago.

The Daily Mail published letters allegedly written by Gary Oliva, 54, who was convicted on child pornography charges, saying he accidentally killed the former child beauty pageant contestant.
