The group’s leader placed toothpicks and glue in the doorways to prevent someone from wandering by and accidentally triggering the large device and the three men furtively drove off in a white van. Next to the bomb, one of the men placed an envelope containing a three-page, immaculately written extortion note entitled “Stern Warning to the Management and Bomb Squad” and demanding $3 million in “unmarked, unbugged and chemically untreated” $100 bills. “The machine”-covered by a cloth with a crudely rendered IBM logo on the side-was an elaborately constructed bomb, replete with more than 1,000 pounds of dynamite attached to a complex network of triggering mechanisms. They used a service elevator to move “the machine”-as they called it-to an unoccupied second-floor executive office. In the early morning of August 26, 1980, three men dressed in blue worker’s coveralls wheeled an object roughly the size of a copy machine through a side entrance of Harveys Resort Hotel at Stateline, Nevada, perched on Lake Tahoe’s placid shores. Harveys’ bomb remains a teaching tool for FBI more than 30 years after the blast
