After 18 months of speculation, accusations and leaks in a quiet town frustrated with being in the spotlight, the police officer in charge of the JonBenet Ramsey case can say this: "I have an idea of who did it."

Police and prosecutors agreed Tuesday that a grand jury could help find the little girl's killers."I have an idea of who did it," said police Cmdr. Mark Beckner after he turned the case over to Boulder County District Attorney Alex Hunter. "If I were the D.A., I would go ahead with a grand jury at this point."
