BOULDER, Colo. — A new prosecutor in Colorado says he plans to take a fresh look at one of the country's most high-profile cold cases — the slaying a dozen years ago of JonBenet Ramsey.

Incoming Boulder County District Attorney Stan Garnett said he'll decide what to do with the investigation in his first 30 days on the job, which he starts Jan. 13. His predecessor, Mary Lacy, publicly exonerated the Ramsey family this year in the Dec. 26, 1996, murder.

Garnett said he might send the case back to the police. The DA's office took over the investigation in 2002 because of criticism of the police department's handling of it.

JonBenet, a 6-year-old beauty pageant contestant, was found bludgeoned and strangled in the basement of her parents' home.
