Child-welfare authorities say an infant taken cross-country by her mother in violation of a custody order has been safely returned to Utah. The mother, Sheila Crump, was arrested in Johnson City Tennessee last week on charges of taking the 9-week-old girl out of state. Utah authorities took custody a day after the infant, Vanesa, was born Aug. 3. She was low-weight and had fetal drug exposure. Utah Department of Human Services spokeswoman Elizabeth Sollis says a caseworker brought Vanesa to Utah on a commercial flight Tuesday. Crump disappeared with the baby from a treatment center a week ago after taking the girl to Primary Children’s Medical Center for an undisclosed medical problem.
