(CNN) -- Previously sealed court documents released Friday show that a Colorado grand jury voted in 1999 to indict the parents of murdered 6-year-old JonBenet Ramsey on charges of child abuse resulting in death and being accessories to a crime.
The district attorney decided that year, however, not to file charges against John and Patricia Ramsey, saying there was insufficient evidence. In 2008, a new district attorney said new DNA evidence cleared the parents and their son in the death.
A Colorado court ordered the release of the previously sealed court documents, putting new attention on the unsolved 1996 death of JonBenet Ramsey, a girl who won child beauty pageants and whose murder shocked the nation. The pages were sealed in 1999, after the grand jury in the case dispersed without charges being filed.
The court documents show how the grand jury sought to charge each parent with two identical counts.

The grand jury had alleged that Patricia Paugh Ramsey, who died from ovarian cancer in 2006, and husband John Bennett Ramsey "did ... permit a child to be unreasonably placed in a situation which posed a threat of injury to the child's life or health which resulted in the death of JonBenet Ramsey."
The grand jury also had alleged that each parent "did ... render assistance to a person, with intent to hinder, delay and prevent the discovery, detention, apprehension, prosecution, conviction and punishment of such person for the commission of a crime, knowing the person being assisted has committed and was suspected of the crime of murder in the first degree and child abuse resulting in death."
The documents provide no further details on who that "person" was. The grand jury had accused the couple of committing the offenses "on or between December 25 and December 26, 1996." JonBenet was found murdered in the basement of the family's Boulder home the day after Christmas 1996.
Ever since their daughter's murder, John Ramsey and his late wife maintained they had nothing to do with it.
