Colorado police have denied claims made in a new Netflix documentary that they are not pursuing viable evidence and credible leads over the killing of six-year-old JonBenet Ramsey.

The girl, who competed in beauty pageants, was found dead in the basement of her family’s home in the college town of Boulder the day after Christmas in 1996.
