Excerpt: A Colorado Springs private investigator who has worked on the JonBenet Ramsey case for almost a decade says he's asking the district attorney and police to take another look at a one-time suspect who he thinks could be a threat to other girls.

Ollie Gray, who initially was hired by the Ramseys and has worked independently on the case for years alongside retired Colorado Springs homicide detective Lou Smit, said Saturday that he believes John Mark Karr has sent a new e-mail indicating he has targeted other girls, that he has killed and will kill again.

Karr, 43, was arrested in Bangkok, Thailand, on Aug. 15, 2006, after he implicated himself in JonBenet's death.
