Despite the murder happening more than two decades ago, the 1996 killing of six-year-old JonBenét Ramsey has continued to fascinate the country, with every new development still being analyzed. The latest bit of news came Friday, when ABC News' "20/20" published a portion of an interview with a grand juror in the case.

The person was granted anonymity by because the penalties for revealing evidence or testimony could include jail time. The grand juror said the parents could have been indicted, but it seemed as if there was not enough evidence to convict anyone with the crime.

"There is no way that I would have been able to say, 'Beyond a reasonable doubt, this is the person,'" the juror told ABC News. "And if you are the district attorney, if you know that going in, it’s a waste of taxpayer dollars to do it."

The murder of Ramsey remains unsolved. She was found dead in the basement of the her family's Boulder, Colorado home, her parents saying kidnappers had left a note demanding $118,000 ransom before they found the body.

Ramsey's parents — John and Patsy — were cleared of involvement in 2008, although court documents later showed a grand jury had wanted to indict them in connection with their daughter's murder. John is alive, but Patsy died in 2006. A man named Mark Karr had been arrested in Thailand a decade ago and confessed to the killing, but he was later cleared by an alibi and DNA evidence.

The grand juror also described to ABC News the scene of where the six-year-old was found: in a spare room in the basement of the Ramsey family home, strangled with a cord around her neck and duct tape covering her mouth. The jurors had been taken out to view the scene.

"In the basement where she was found, it was actually kind of an obscure layout," the juror said to ABC News, which will air the full interview Friday night. "You come down the stairwell and you had to go into another room to find a door that was closed. It was a very eerie feeling. It was like, 'Somebody had been killed here.'"

With interest in the case still high, the Colorado district attorney said Thursday the former prosecutor should not have cleared the parents of the girl, according to CBS News. Authorities are reportedly looking at new DNA testing technology after a report this year that indicated there were serious flaws in how the results were previously interpreted.
