A Columbia man pleaded guilty in federal court on Tuesday to attempting to purchase a chemical weapon, capable of killing hundreds of people, on the dark web with Bitcoin.
Jason William Siesser, 45, pleaded guilty before U.S. Magistrate Judge Willie J. Epps, Jr. to one count of attempting to acquire a chemical weapon and one count of aggravated identity theft, a Tuesday press release said.
The press release explained Siesser’s guilty plea saying that Seisser admitted to attempting to buy a chemical weapon with ill intentions.
By pleading guilty today, Siesser admitted that he attempted to acquire a chemical weapon on two occasions between June 14 and Aug. 23, 2018, and that he did not attempt to acquire that chemical weapon for a peaceful or protective purpose.
The release went on to say Siesser provided a shipping address using the name of a juvenile without them knowing. It also said the weapon Siesser attempted to purchase was capable of killing “many people.”
He provided a shipping address in the name of a juvenile, whose identity he used without authorization, to place the orders for a highly toxic chemical in amounts capable of killing many people. Siesser paid for the chemical weapon with the digital cryptocurrency known as Bitcoin.
Siesser ordered two 10ml units of the chemical on July 4, 2018, and paid for the weapon with Bitcoin. Following his purchase, the seller did not immediately ship the chemical weapon. The release said Siesser continued to contact the seller and two weeks later, on July 18, Siesser told the seller that, “I plan to use it soon after I receive it.”
Siesser subsequently ordered three more 10ml units of the chemical weapon on Aug 5, 2018. Siesser again paid for the order with Bitcoin (the equivalent of $150) and provided a shipping address in the name of a juvenile. The release said this quantity of the chemical weapon has the capacity to kill approximately 300 people.
A controlled delivery of a package that contained an inert substance was made to Siesser’s residence on Aug. 23, 2018. Siesser believed the package contained the chemical weapon he had ordered, signed for the package, and took it inside the residence.
Subsequently, law enforcement officers executed a search warrant at Siesser’s residence. On top of a shelf in the garage, officers found the substance Siesser believed to be a chemical weapon.
Officers also located two separate and seemingly unopened shipping boxes on the shelf next to it. They contained approximately 10 grams of cadmium arsenide, a toxic compound, which can be deadly if ingested or inhaled; approximately 100 grams of cadmium metal; and approximately 500 ml of hydrochloric acid.
The release said an invoice for these products showed they had been ordered together on March 30, 2018.
Writings located within the home “articulated Siesser’s heartache, anger, and resentment over a breakup, and a desire for the person who caused the heartache to die,” the release said.
Siesser is subject to a mandatory minimum sentence of five years in federal prison without parole, up to a sentence of life in federal prison without parole.
Siesser’s cases was investigated by the FBI with assistance from the Columbia Police Department.
