A 22-year-old University of New Hampshire student was found dead Sunday afternoon in a marshy area near the campus after he was reported missing a day earlier, authorities said. Vincenzo Lirosi disappeared after a night of drinking, police said, and he was last seen early Saturday morning shortly after leaving a fraternity party where he reportedly got into a fight, a pal of his, Jordan Blanchard, told WMUR-TV. “It’s pretty uncharacteristic of him,” Blanchard told the news station. “This is his first fight ever.”
