A recovering heroin addict from Italy last seen after crossing the finish line at Sunday's New York City Marathon was found Tuesday aboard a subway train, police said. Gianclaudio Marengo, 30, was still wearing his racing attire of a turquoise shirt and black shorts when an off-duty police officer on his way to work noticed him on a midtown Manhattan train at about 6:40am. He had been missing for close to 40 hours. "We don't know what happened to him in New York," said Matteo Diotalevi, a spokesman for the San Patrignano drug rehabilitation center on the Adriatic coast. "But he's a fragile person."
Marengo was among a group of eight Italian recovering addicts who joined more than 50,000 other runners in the 45th running of the marathon, Diotalevi said. He was separated from his group at the finish line since all the runners finished at different times; Marengo completed the marathon in four hours and 44 minutes, CBS New York reports. Police said they were told by the group that Marengo was mentally disabled but Diotalevi denied that he had any mental health issues. The officer who found Marengo persuaded him to get off the train and get a doughnut and coffee together. Eventually, the officer showed Marengo his photo in a newspaper, and Marengo confirmed he was the same person shown. He was taken to a police station and then to a hospital to be treated for dehydration, authorities said. (Read more marathon stories.)
