DA taking new look at JonBenet Ramsey slaying

DENVER - A prosecutor who&#39;s taking a new look at JonBenet Ramsey&#39;s slaying is to work with a retired police detective once hired by the girl&#39;s parents who believes an intruder killed her in 1996. <br> <br> Boulder, Colorado, district attorney Mary Keenan says she would also focus on leads that had NOT been investigated previously. <br> <br> Boulder Police Chief Mark Beckner said earlier this month that Keenan started an aggressive review of the case because JonBenet&#39;s parents, who have a home in Atlanta, and Wood do not believe police were following up on leads. <br> <br> Beckner said the review could help the Ramseys and Wood feel more comfortable sharing information or leads with investigators.
