ATLANTA — Entering court using a walker, a doctor’s note clutched in his hand, 70-year-old Dana Williams, who suffers serious heart problems, hypertension and asthma, pleaded to delay eviction from his two-bedroom apartment in Atlanta. Although sympathetic, the judge said state law required him to evict Williams and his 25-year-old daughter De’mai Williams in April because they owed $8,348 in unpaid rent and fees on their $940-a-month apartment. They have been living in limbo ever since. They moved into a dilapidated Atlanta hotel room with water dripping through the bathroom ceiling, broken furniture and no refrigerator or microwave.
