A man charged with driving into three pedestrians on a Hartford sidewalk and trying to flee after Saturday’s St. Patrick’s Day parade has posted $50,000 bail and was ordered to appear in court next week. Geraldo Luciano, 27, of Windsor is charged with reckless endangerment, reckless driving, and making an improper U-turn. He is to be arraigned March 20 in Hartford Superior Court. Police said Luciano hit three pedestrians on Trumbull Street, sped away, got into another accident and fled again before being arrested on Interstate 91 near the Hartford-Windsor line. Authorities said the pedestrians were taken to a hospital with injuries not believed to be life-threatening.
