At his desk, steps from an exposed toilet with two rolls of tissue, a sink, bed, small white refrigerator and microwave, Anthony Sperduto displayed computer images of his life as it once was. There on the screen were pictures with ex-wife, Maritza, at a banquet, business trips to Hawaii and views of a meticulously decorated, four-bedroom, 2,400-square-foot Texas house with 12-foot ceilings and a copy of Michelangelo’s Creation of Adam above a fireplace. As Sperduto, 53, tells it, his world began to collapse in the fall of 2006, starting with a blackout at work, loss of an executive position and back problems that became debilitating. Three years later, Christmas Eve, to be exact, the 6-foot-7 Navy veteran found himself broke and homeless in Florida.
