NEW YORK (AP) — As investigators look into whether a medical problem may have caused a motorist to plow into a group of New York City trick-or-treaters, killing a 10-year-old girl and two others, mourners remembered the victims. "I had a lot of dreams for Nyanna. I had so many plans for her," Natalia Perez said the day after her daughter, Nyanna Aquil, was pronounced dead at a hospital.
