A woman wanted for a weekend murder in deep south Shreveport is now in the Caddo Correctional Center.  28-year-old Stacey Nichole Blount-Juneau was arrested Saturday in Natchitoches after a car registered to a Shreveport woman was found abandoned there.  68-year-old Rose Coleman had been found dead near the old AT&T plant Saturday morning by a jogger.  Natchitoches police were able to link Blount-Juneau to Coleman's car and to a number of criminal offenses in their jurisdiction.  Then, working with their Shreveport counterparts, she was linked to Coleman's murder here and Shreveport police were able to obtain an arrest warrant.  She was held in Natchitoches until a Caddo deputy was able to drive down, pick her up, and bring her back here.  She's now being held at CCC on a charge of second-degree murder and two in-state fugitive warrants.  CCC booking records show that she also spent time there twice last year on theft charges.
