WMD Cases


Steven Ekberg

Containers of poisons.An anonymous phone call was made to 9-1-1 claiming that Steven Ekberg possessed an arsenal of firearms, including machine guns, and a box of poisons, including ricin. The caller stated that he used to be Ekberg’s roommate and that he saw the items several months before the day he called 9-1-1. Since then, Ekberg had moved back to his mother’s home. The caller stated that Ekberg said he would use the firearms and poison “if, like, the government ever, like, tried to screw him over.”

Ekberg worked as a waiter at various restaurants in Ocala, Florida. He was depressed and was mixing prescription drugs with cocaine and alcohol. He had threatened suicide in the past. The caller stated that Ekberg possessed a cardboard box containing several vials, glass tubes, and jars all containing poisons. When Ekberg referred to the poisons he stated, “If I put this in your drink you would die and nobody would be able to trace it to me. If I put this in your food you would get really, really sick but you wouldn’t die, but it would be painful.” He also stated that the substance was “really illegal.”

FBI agents went to Ekberg’s home, where his mother gave consent to search the residence. During the search, they found a recipe for making ricin and a military manual on explosives and demolition, incendiaries, and guerrilla warfare. They also removed Ekberg’s computer from the residence. Ekberg later confessed to attempting to manufacture ricin by partially following a recipe that was stored on his computer.

Ekberg was arrested and indicted on one count of the Biological Weapons Anti-Terrorism Act. On May 3, 2005, he pleaded guilty and was sentenced to 26 months in a federal prison.

Myron Tereshchuk

Items seized during the case were castor beans, laboratory glassware, numerous chemical reagents, unidentified liquids, crystalline solids, electrical components, and inert hand grenades.

On March 10, 2004, FBI agents executing a search warrant on a Maryland home for an extortion/computer intrusion investigation discovered ingredients that could be used to produce the deadly biological toxin ricin and other potential weapons of mass destruction.

Among the items found were castor beans, laboratory glassware, numerous chemical reagents, unidentified liquids, crystalline solids, electrical components, and inert hand grenades.

Myron Tereshchuk, who lived in the house, was arrested and admitted to initiating the process of ricin production. A copy of the U.S. patent for ricin production was found on Tereshchuk. Laboratory analysis identified the liquids and solids to be ricin, nicotine sulfate (a chemical used in pesticides), and explosive powder. Also found in the house were incendiary explosive devices, including practice grenade bodies that had been modified to hold explosive powder.

On May 13, 2005, Tereshchuk pled guilty to possession of a biological weapon and possession of explosives. He was sentenced to three years and five months in prison for each charge. He was additionally sentenced to three years of supervised release.


Noel Davila

On August 20, 2002, the Connecticut State Attorney’s Office (CSAO) received a threatening letter containing white powder. The letter mentioned anthrax and referenced Usama bin Laden. Laboratory analysis determined the white powder did not contain anthrax. While awaiting these results, the CSAO was closed for two days.

The envelope sent by Davila.

Our investigation revealed the letter was sent from the Connecticut Department of Corrections Facility in Cheshire. A human source was developed at the facility who stated that Noel Davila was responsible for mailing the letter. In several recorded meetings with the witness, Davila outlined the entire process of preparing and mailing the letter.

In June 2004, Davila was convicted of a threatened use of a weapon of mass destruction and delivery of a threat through the U.S. mail. On May 11, 2005, he was sentenced to five years in prison for the delivery of a threat through the U.S. mail and 30 years in prison for the threatened use of a weapon of mass destruction.

Twin Sisters Plot

In 1999, three members of the San Joaquin County, California, militia, a right-wing militant group, plotted to destroy two propane tanks in Elk Grove, California.

The tanks, each holding approximately 12 million gallons of liquid propane, were part of the largest above-ground propane facility in North America. The members—Donald K. Rudolph, Kevin Ray Patterson, and Charles Dennis Kiles—dubbed the two tanks the “Twin Sisters” and viewed the propane tank farm as “a target of opportunity.”

The plot originated in 1996, when many militia groups were tasked to identify targets in their area that were susceptible to sabotage and that, if destroyed, would cause a major disturbance and lead the government to declare martial law. This was part of a larger conspiracy by militia groups to undermine and destabilize the federal government. Rudolph, Patterson, and Kiles intended to follow through with the plan in late 1999.

It is estimated that the explosion would have caused 12,000 deaths, widespread fire, and third-degree burns among individuals within five miles or more of the explosion.

During the FBI investigation, Rudolph agreed to assist in exchange for not being charged in this matter and instead pleaded guilty to a previous charge of plotting to assassinate a U.S. District Court judge in 1998.

In 2002, Patterson and Kiles were convicted of threatened use of a weapon of mass destruction. Patterson was sentenced to 21 years in federal prison and five years supervised release. Kiles was sentenced to 22 years in federal prison and five years supervised release. Rudolph was sentenced to five years in federal prison.

Stuart Adelmann

In August 1996, Stuart Adelmann, posing as Brian Stuart Von Adelmann, Ph.D., used a counterfeit Nuclear Regulatory Commission (NRC) license to order the following radioactive materials: Sodium-22, Cadmium-109, and Carbon-14.

Adelmann was arrested on August 29, 1996, and charged with violating Title 18 U.S. Code, Section 831 – Prohibited Transactions Involving Nuclear Materials. This was the first indictment and prosecution using Title 18 USC 831.

Adelmann pled guilty and was sentenced to five years in federal prison.
