Following a magnitude 6.2 earthquake that devastated parts of central Italy in August, rescue efforts are continuing, but not for survivors. The powerful quake killed nearly 300 people, left thousands homeless and caused nearly $5 billion in property damage, including ancient structures and other works of art that contribute to Italy's rich cultural heritage. Thousands of significant pieces of artwork have gone missing in the earthquake zone, with an intensive search now centered on the hard-hit town of Amatrice. The search is being conducted by a group of fire and rescue service workers known as the Art Squad. NewsHour Weekend Special Correspondent Christopher Livesay reports on their efforts and the race against time.
