WINONA, Minn. – Almost shoulder to shoulder 100 volunteers combed a section of the Yucatan Wildlife Management Area in Houston County without success for clues to the disappearance of 26-year-old Maddi Kingsbury of Winona. She disappeared March 31 under suspicious circumstances. Winona police t organized initial massive searches, with 2,600 people one weekend, but have shifted the official investigation since to concentrate on tips and literally hundreds of clues that have accumulated. Petra Eastling of Minnesota United, a Minneapolis-based missing persons group, said that Winona police have suggested areas to go to, including the Yucatan wildlife area 30 miles south of Winona. The area is adjacent to the road-accessible but now abandoned Whispering Hills girls camp.
