Colorado ? Police investigating the death of child beauty queen JonBenet Ramsey are conducting a new round of interviews, based on recommendations from an advisory committee.

The committee, which included investigators from several state and federal agencies, met in 2009 after police took the lead in the case back from Boulder County prosecutors.

Members reviewed evidence in the death of 6-year-old JonBenet, whose body was found bludgeoned and strangled in her family’s home in Boulder on Dec. 26, 1996. Former District Attorney Mary Lacy said in 2008 that evidence suggests the killer was an unknown stranger, not a family member. Police Chief Mark Beckner wouldn’t reveal details about the continuing investigation or who police want to interview now.
