The 18-year-old unlicensed driver, who ran over a cop and dragged him 100 feet this past week — 15 months after little Ariel died — was brought to the New York-Presbyterian/Lower Manhattan emergency room after complaining of chest pains, sources said. Reyes and his lawyer were meeting with prosecutors in the late afternoon to discuss his legal options. Reyes was cleared to leave the ER around 9:15 p.m.
