An Amarillo jury has found 22-year-old Khalid Aldawsari guilty of attempted use of a weapon of mass destruction.
He faces up to life in prison. Aldawsari was accused of collecting supplies to build a bomb and authorities said they found writings that indicated his desire to carry out an attack.
Prosecutors stressed the "substantial" steps he made toward building a bomb, while the defense said that he didn't actually threaten anyone.
Sentencing has been set for October 9th. Aldawsari faces up to life in prison and up to a $250,000 fine.
The U.S. Department of Justice released a statement about the verdict on Wednesday:
According to court documents and evidence presented during trial, at the time of his arrest last year, Aldawsari had been researching online how to construct an IED using several chemicals as ingredients. He had also acquired or taken a substantial step toward acquiring most of the ingredients and equipment necessary to construct an IED and he had conducted online research of several potential U.S. targets, the affidavit alleges. In addition, he had allegedly described his desire for violent jihad and martyrdom in blog postings and a personal journal.
"While many people are responsible for thwarting Aldawsari's threat and bringing him to justice, we owe a debt of gratitude to all the members of the North Texas Joint Terrorism Task Force, and especially to the hundreds of hard-working and dedicated FBI agents, analysts, linguists and others," said U.S. Attorney Saldaña. "Their efforts, coupled with the hard work and excellent cooperation from the Lubbock Police Department and the Texas Tech Police Department, are the reason we were able to stop this defendant from carrying out a catastrophic act of terrorism."
"As this trial demonstrated, Aldawsari purchased ingredients to construct an explosive device and was actively researching potential targets in the United States. Thanks to the efforts of many agents, analysts and prosecutors, this plot was thwarted before it could advance further," said Assistant Attorney General Monaco. "This case serves as another reminder of the need for continued vigilance both at home and abroad."
"Today's guilty verdict shows how individuals in the United States with the intent to do harm can acquire the knowledge and materials necessary to carry out an attack," said SAC Rodriguez. "Our success in locating and preventing Mr. Aldawsari from carrying out an attack is a result of cooperation within the law enforcement and intelligence communities, particularly, the North Texas Joint Terrorism Task Force, the Texas Tech Police Department, the Lubbock Police Department, and the Lubbock County Sheriff's Office, but also a demonstration of information sharing across FBI divisions, as well as assistance from the community. I want to thank the dedicated agents, officers and analysts, the computer forensics team and linguists that worked diligently on this investigation as well as prosecutors serving in the U.S. Attorney's Office in the Northern District."
The government presented evidence that on Feb. 1, 2011, a chemical supplier reported to the FBI a suspicious attempted purchase of concentrated phenol by a man identifying himself as Khalid Aldawsari. Phenol is a toxic chemical with legitimate uses, but can also be used to make the explosive trinitrophenol, also known as T.N.P., or picric acid. Ingredients typically used with phenol to make picric acid, or T.N.P., are concentrated sulfuric and nitric acids.
Aldawsari attempted to have the phenol order shipped to a freight company so it could be held for him there, but the freight company told Aldawsari that the order had been returned to the supplier and called the police. Later, Aldawsari falsely told the supplier he was associated with a university and wanted the phenol for "off-campus, personal research." Frustrated by questions being asked over his phenol order, Aldawsari cancelled his order, placed an order with another company, and later emailed himself instructions for producing phenol. In December 2010, he had successfully purchased concentrated nitric and sulfuric acids.
Aldawsari used various email accounts in researching explosives and targets, and often sent emails to himself as part of this process. He emailed himself a recipe for picric acid, which was described in the email as a "military explosive" and also emailed himself instructions on how to convert a cell phone into a remote detonator and how to prepare a booby-trapped vehicle using household items. Aldawsari also purchased many other items, including a Hazmat suit, a soldering iron kit, glass beakers and flasks, a stun gun, clocks and a battery tester.
Excerpts from a journal found at Aldawsari's residence indicated that he had been planning to commit a terrorist attack in the United States for years. One entry describes how Aldawsari sought and obtained a particular scholarship because it allowed him to come directly to the United States and helped him financially, which he said "will help tremendously in providing me with the support I need for Jihad." The entry continues: "And now, after mastering the English language, learning how to build explosives and continuous planning to target the infidel Americans, it is time for Jihad."
In another entry, Aldawsari wrote that he was near to reaching his goal and near to getting weapons to use against infidels and their helpers. He also listed a "synopsis of important steps" that included obtaining a forged U.S. birth certificate; renting a car; using different driver's licenses for each car rented; putting bombs in cars and taking them to different places during rush hour; and leaving the city for a safe place.
Aldawsari conducted research on various targets and emailed himself information on these locations and people. One of the documents he sent himself, with the subject line listed as "Targets," contained the names and home addresses of three American citizens who had previously served in the U.S. military and had been stationed for a time at Abu Ghraib prison in Iraq. In others, Aldawsari sent himself the names of 12 reservoir dams in Colorado and California and listed two categories of targets: hydroelectric dams and nuclear power plants. He also sent himself an email titled "Tyrant's House," in which he listed the Dallas address for former President George W. Bush. Aldawsari also conducted research that indicated he considered using infant dolls to conceal explosives and the possible targeting of a nightclub with an explosive concealed in a backpack.
This case was investigated by the FBI's Dallas Joint Terrorism Task Force, with assistance from the Lubbock Police Department and the Texas Tech Police Department. The prosecution is being handled by Assistant U.S. Attorneys Jeffrey R. Haag, Denise Williams, James T. Jacks and Matthew J. Kacsmaryk and Trial Attorney David Cora from the Counterterrorism Section of the Justice Department's National Security Division.
