By William Hankins
 
The story of William "Bill" Hankins is a riveting firsthand account of the nation's first prison gang investigator. Sergeant Hankins discovered the existance of the notorious Mexican Mafia and Nuestra Familia during their formative years at San Quentin. When the Black Guerilla Family and Aryan Brotherhood followed in rapid succession, Hankins became the sought after Department of Corrections official called to educate the law enforcement and correctional community about these four destructive prison gangs, also referred to as California's "axis of evil." Recognized by his peers as the "gang guy," the Alpha Guard's journey will forever be remembered as the trail blazed by the pioneer of organized prison gang investigators.
