French rescuers in Haiti pulled a teenage girl from the rubble of a home on the campus of the destroyed College St. Gerard on Wednesday, a stunning recovery 15 days after an earthquake devastated the city.Darlene Etienne, 17, was covered with a thermal blanket and given oxygen as rescuers rushed her on a stretcher to a French-run field hospital for treatment.Her family said Etienne had just started studying when the disaster struck, trapping scores of people in the rubble of university buildings, hostels and homes."We thought she was dead," her cousin, Jocelyn A. St. Jules, said in a telephone call from Marche Dessalines, a town north of the capital.
