Where Is Missing Mayo Clinic Staffer Maddi Kingsbury?

Two thousand volunteers spent their Easter weekend searching for clues in the disappearance of Madeline Kingsbury. The 26-year-old, affectionately known as Maddi, was reported missing from her home nearly two weeks ago. Her distraught family appeared at a news conference wearing shirts emblazoned with her missing poster. The mother of two works as a clinical research coordinator at the world-renowned Mayo Clinic in Rochester, Minnesota.
