When convicted murderer Gary Tison broke out of an Arizona prison with the help of his sons in 1978, it was an embarrassment to the state. Then it became a nightmare. Tison and his gang murdered six people before they were stopped near the Mexican border. Clarke's story of that manhunt is a chilling account of both cold-blooded murder and astonishing corruption within the state penal system. "Last Rampage" is a tale of criminal ruthlessness that has been called the "In Cold Blood" of the American West. Twenty years later, overtaxed law enforcement and overcrowded prisons can only make us wonder if such an incident could happen again.
