A grand jury was convened beginning September 15, 1998 to consider indicting the Ramseys for charges relating to the case. In 1999, the grand jury returned a true bill to charge the Ramseys with placing the child at risk in a way that led to her death and with obstructing an investigation of murder, based on the probable cause standard applied in such grand jury proceedings. But Boulder County District Attorney Alex Hunter did not prosecute them, because he did not believe that he could meet the higher standard of proving guilt beyond a reasonable doubt that is required for a criminal conviction.
