The device filled an entire room at Harvey’s Resort Hotel. John Birges, a California gardener who had lost heavily at the casino, constructed it from over 1,000 pounds of dynamite, TNT, and C-4 plastic explosive, rigged with a complex system of blasting caps, switches, and anti-tamper mechanisms. He demanded the money or he would destroy the building. After evacuating the hotel, the FBI called in its bomb squad, which used a robot to drill into the device’s casing to inject a disabling liquid.
The drill bit sparked. The resulting explosion at 3:16 AM destroyed the bomb room, sent a shockwave through Stateline, and blew out windows blocks away. It left a crater in the hotel’s foundation. Birges had designed the bomb not to be moved or disarmed, only to be paid. The FBI’s attempt to outsmart it proved his point. He was arrested months later after bragging about the crime.
The event is a footnote in criminal history, but it marked a turning point in bomb disposal doctrine. The sheer destructive power, contained in a single room, shocked investigators. It demonstrated the lethal potential of a sufficiently motivated amateur and the limits of technological intervention. The Harvey’s bomb became a permanent case study in FBI and military bomb squad training, a humbling lesson in the perils of overconfidence when facing an adversary’s ingenuity.
