America’s “supermax” prisons are supposed to be inescapable fortresses, designed to keep the worst of the worst safely locked away from society. But with enough time, preparation–and sheer guts—it’s amazing what ingenious convicts are capable of pulling off. America’s Greatest Prison Breaks features a blow-by-blow account of the recent breakout of escaped killers Richard Matt and David Sweat from Clinton Correctional Prison in upstate New York, as it was experienced and investigated by U.S. Marshals and other officials on the case. It also takes a look at some of the most amazing prison escapes in American history. From the greatest unsolved escape of all–Alcatraz–to the clever con artist Richard McNair, who literally mailed himself out of federal prison. How did they do it? America’s Greatest Prison Breaks takes a close, hard look at how these cunning criminals pulled off the impossible.
