BOULDER, Colo. (AP) _ Prosecutors, criminologists, forensic scientists and police will hold their first comprehensive review of evidence in the JonBenet Ramsey case next week.

Boulder District Attorney Alex Hunter then hopes to decide within a month whether to present the case to a grand jury.

Evidence to be presented beginning June 1 will include hundreds of interviews and more than 30,000 pages of reports about the slaying of the 6-year-old beauty queen on Dec. 26, 1996.

``We'll talk about people we have looked at as suspects and people we have eliminated as suspects,'' said police Cmdr. Mark Beckner. ``We are going to cover a lot of ground.''

A grand jury, with its sweeping subpoena power, could offer investigators a chance to question the little girl's parents, John and Patsy Ramsey, who have spoken to police only once about the slaying. They refused a police request for a second interview.

Ramsey attorney Pat Furman said the couple welcomes the change a grand jury could make in the investigation.

``The lack of progress has been extremely frustrating for John and Patsy, and they're hopeful that this new phase of the investigation will get things back on track,'' he said.

No suspects have been named in the case, but Beckner has said the Ramseys are under an ``umbrella of suspicion.'' They deny any involvement in their daughter's slaying.
