Police say mild conditions have increased the chances that a young girl missing for 4 nights in NSW’s Blue Mountains might still be alive. Charlise Mutten disappeared from celebrity wedding venue Wildenstein Garden at Mount Wilson on Thursday, where she’s been staying with her family on holiday from Queensland. Police were informed on Friday, and 100 emergency services personnel have been out searching for her in rugged bushland. Yesterday, reports said police are investigating it as a possible homicide, and a boat and a ute have been seized for forensic examination. Charlise lives with her grandmother on the Gold Coast but was away with mother Kallista Mutten and her fiancé Justin Stein, whose family owns Wilderstein. It’s not suggested that the couple are involved in the girl’s disappearance. “We won’t rule anything in, and we don’t rule anything out,” said Blue Mountains Police Chief Inspector Garry Sims, adding they have grave concerns for her safety.
