As the grand jury investigation of the JonBenet Ramsey case nears conclusion, experts see little chance the dead child’s parents will be called to testify. Robert Pugsley, a professor of criminal law at Southwestern University School of Law in Los Angeles, says it’s “very doubtful” either John Ramsey or his wife Patsy will be called, despite the fact that they are at the center of the investigation. Pugsley told the Boulder (CO) Daily Camera prosecutors working toward indicting one or both of them might worry that the couple could win over the grand jury. “Any time (a prosecutor) calls the defendant in, it jeopardizes his case.” The term of the grand jury expires April 22, and prosecutors have asked for expenses through March, suggesting the investigation is about to wrap up. The panel has been meeting twice a week since Sept. 15. Boulder District Attorney Alex Hunter called the investigation at the request of police, who were unable to make an arrest in 21 months of investigation.
