"There's a killer on the loose," Patsy Ramsey said a few days after her daughter's body was found. "I don't know who it is. I don't know if it's a she or a he, but ... there's someone out there."
Investigators say they did not find any sign of forced entry into the family home in 1996. No footprints were found in the snow outside the home, either.
A paintbrush from her mother's hobby kit was used to tighten the rope that choked JonBenet, according to investigators. An alleged ransom letter came from a notepad inside the house and made reference to little-known details about the family's past finances.
In October 1999, grand jurors assigned to the case went back home, sworn to silence. The eight women and four men had convened regularly for 13 months. They heard from dozens of witnesses, considered 30,000 pieces of evidence.
Today, the investigation stands almost where it started -- no arrests and no solid suspects.
Judge J. Robert Lowenbach last week ordered the release of four pages of sealed documents, as requested by Boulder journalists.
The court documents show how the grand jury sought to charge each parent with two identical counts.
The grand jury had alleged that Patsy Ramsey, who died from ovarian cancer in 2006, and John 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."
CNN legal analyst Jeffrey Toobin said the indictment merely shows that a majority of the grand jurors felt there was probable cause to charge the parents -- a lower standard than proving guilt beyond a reasonable doubt.
