Book excerpt: FBI Forensic Artist and Laboratory Supervisor Gene O'Donnell traveled the world for 32 years to draw the faces of criminals waiting for him in the memories of their victims. Sometimes the only witnesses he had were the skeletal remains found along a lonesome highway. Spies, bank robbers, lost and missing kids, aspiring presidential assassins, rapists, anybody wanted by police, Gene drew. With few leads, these drawings were often the only thing that allowed investigators to track down suspects. This memoir takes the reader on fascinating journeys of true crimes. See how age-progressed images of two kidnapped children led Unsolved Mysteries to the Fontes boys, who, though missing for many years, were recognized and rescued, while their kidnappers were brought to justice. Experience the victory of helping to find the worst that mankind has to offer and the heartbreak over the ones that got away.
