A Byte Out of History: The Case of the Harvey's Casino Bomb

In the early morning hours of August 26, 1980—30 years ago—men wearing white jumpsuits and pretending to deliver an IBM copy machine rolled a bomb into Harvey’s Resort Hotel and Casino in Stateline, Nevada, near Lake Tahoe.

So began one of the most unusual cases in our history.

A note left with the bomb—titled STERN WARNING TO THE MANAGEMENT AND BOMB SQUAD—began ominously: “Do not move or tilt this bomb, because the mechanism controlling the detonators in it will set it off at a movement of less than .01 of the open end Ricter scale.”

 The Extortion Note

When authorities discovered the Harvey’s bomb, they also found a typewritten note, transcribed here exactly as it was written:

TO THE MANAGEMENT:

STERN WARNING TO THE MANAGEMENT AND BOMB SQUAD:

Do not move or tilt this bomb, because the mechanism controlling the detonators in it will set it off at a movement of less than .01 of the open end Ricter scale. Don’t try to flood or gas the bomb. There is a float switch and an atmospheric pressure switch set at 26.00-33.00. Both are attached to detonators. Do not try to take it apart. The flathead screws are also attached to triggers and as much as ¼ to ¾ of a turn will cause an explosion. In other words this bomb is so sensitive that the slightest movement either inside or outside will cause it to explode.

“Do not try to take it apart,” the note went on. “The flathead screws are also attached to triggers and as much as ¼ to ¾ of a turn will cause an explosion. …This bomb is so sensitive that the slightest movement either inside or outside will cause it to explode. This bomb can never be dismantled or disarmed without causing an explosion. Not even by the creator.” (Read the full text of the extortion note and see more pictures.)

An investigator examines the Harvey's bomb, which contained nearly 1,000 pounds of dynamite and a variety of triggering mechanisms that made it virtually undefeatable.

The “creator,” we later discovered, was 59-year-old John Birges, Sr.—who wanted $3 million in cash in return for supplying directions to disconnect two of the bomb’s three automatic timers so it could be moved to a remote area before exploding.

The device—two steel boxes stacked one atop the other—contained nearly 1,000 pounds of dynamite. Inside the resort, Birges made sure the bomb was exactly level, then armed it using at least eight triggering mechanisms.

“We had never seen anything quite like it,” said retired Special Agent Chris Ronay, an explosives examiner who was called to the scene along with other experts.

After being discovered, the bomb was photographed, dusted for fingerprints, X-rayed, and studied. Finally, more than 30 hours later, a plan was agreed upon: if the two boxes could be severed using a shaped charge of C4 explosive, it might disconnect the detonator wiring from the dynamite.

Harvey’s and other nearby casinos in Lake Tahoe were evacuated, and on the afternoon of August 27, the shaped charge was remotely detonated.

The plan was the best one available at the time, but it didn’t work. The bomb exploded, creating a five-story crater in the hotel. “Looking up from ground level,” Ronay said, “you could see TV sets swinging on electric cords and toilets hanging on by pipes. Debris was everywhere.” Fortunately, because of the evacuation, no one was killed or injured.

To this day, the Harvey’s bomb remains one of the most unique improvised explosives devices (IEDs) the Bureau has ever come across.

“Today’s IEDs use more advanced electronics,” said Special Agent Thomas Mohnal, an examiner in our Explosives Unit, based at the FBI Laboratory in Quantico, Virginia. “Our techniques and tools for dealing with these devices are also more advanced,” Mohnal added, “but you still probably couldn’t build a bomb much tougher to defeat than Harvey’s.”

Birges, Sr., said to be an inveterate gambler who had lost a substantial amount of money at Harvey’s, was caught (with the help of an alert clerk at a nearby hotel who had written down the license plate of the bomb delivery van) and convicted—he never did get the ransom money. His two sons, charged as accomplices, were given suspended sentences because they cooperated with authorities. Birges died in jail in 1996.

Today, a mockup of the Harvey’s bomb—built for Birges’ trial—with all its booby traps and fusing mechanisms, is used for training purposes by our Laboratory Division.

Detainee Denies Participation in Singapore, Indonesia Bombings

April 13, 2007 – An alleged al Qaeda leader being held at Guantanamo Bay, Cuba, denied involvement in bombings in both Indonesia and Singapore, according to a transcript of his hearing released yesterday. Riduan bin Isomuddin, known as "Hambali," either declined to answer or said he had no involvement with the operations brought forth during his April 4 combatant status review tribunal hearing at the detention facility.

The tribunal was an administrative hearing to determine only if the detainee could be designated as an enemy combatant.

Hambali said that while he was a member of Jemaah Islamiyah, a Southeast Asian militant Islamic organization, he had no interaction with al Qaeda.

Evidence presented during the hearing showed that he had been the operations chief of Jemaah Islamiyah and served as its main contact for al Qaeda in Southeast Asia. He also helped recruit members for al Ghuraba, the foreign student organization that helped develop Jemaah Islamiyah organization in Pakistan.

He also had served as the leader of the Malaysia Mujahedin group, according to U.S. government information presented in the hearing. That group's mission is to topple the Indonesian government. During the hearing, a Federal Bureau of Investigation source was cited as having contact with Hambali when he orchestrated and funded the December 2000 bombing of a church in Indonesia that killed 18 people.

An FBI source also stated that in January 2002 the detainee discussed carrying out attacks in bars, cafes and night clubs frequented by westerners in Thailand, Malaysia, Singapore, the Philippines and Indonesia. The source said the detainee claimed to have 1 ton of explosives within Indonesia.

After Hambali allegedly discussed bombing such places and having large amounts of explosives, at least 187 people were killed and more than 300 foreign tourists were injured in October 2002 when an explosion destroyed a nightclub on the Indonesian resort island of Bali.

In his hearing, Hambali denied having supervised the plan to bomb the U.S., Australian and British embassies in Singapore. However, an FBI source stated that the detainee served as the point man between al Qaeda operatives and the mastermind in this plan, which government officials called the "Singapore plot."

Other evidence presented during the hearing showed that a document seized during Hambali's arrest provided instructions for manufacturing vest bombs used by suicide bombers. However, Hambali said he had "no answer" when he was asking during the hearing what his involvement was in making explosives.

The hearing came to a close when the hearing president said an assessment would be made as to whether the detainee continued to pose a threat to the United States or coalition partners in the ongoing conflict against terrorist organizations. The detainee was told that he would have the opportunity to be heard and to present relevant information later to an administrative review board.

The government implemented the CSRTs in July 2004 in response to a June 28, 2004, Supreme Court ruling in the case of Rasul v. Bush. The court ruled that enemy combatants held by the U.S. government had the right to contest their status before a judge or other neutral decision maker.

Between July 2004 and March 2005, DoD conducted 558 CSRTs at Guantanamo Bay. At the time, 38 detainees were determined to no longer meet the definition of enemy combatant, and 520 detainees were found to be enemy combatants.
