A 21-year-old resident of Kent, Washington, pleaded guilty on July 22 in U.S. District Court in Seattle to conspiring to provide material support to a foreign terrorist organization, according to First Assistant U.S. Attorney Charles Neil Floyd. Saed Ali Mirreh was arrested in November 2025 as he prepared to board a plane bound for Turkey with the intention of crossing into Syria to join the Islamic State of Iraq and al-Sham (ISIS).
Mirreh was initially charged in the District of New Jersey alongside coconspirator Tomas-Kaan Jimenez-Guzel, age 19. The case was transferred earlier this month to the Western District of Washington. U.S. District Judge Richard A. Jones scheduled sentencing for October 16.
According to the plea agreement, Mirreh began communicating with co-conspirators as early as July 2025 about traveling through Turkey and ultimately joining ISIS as fighters. The agreement states that Mirreh knew ISIS had been designated a foreign terrorist organization and that he purchased an airline ticket from Seattle to Istanbul for November 16, 2025, intending to meet other members before traveling onward.
The arrest came after members of the conspiracy residing in Dearborn, Michigan, were arrested on October 31, 2025, for plotting an attack within the United States on behalf of ISIS. Following those arrests, Mirreh and Jimenez-Guzel moved up their flight plans, but Mirreh was taken into custody at his residence on November 4.
Communications between coconspirators detailed plans regarding participation in “jihad,” physical training routines, weapons including firearms and improvised explosive devices, and strategies for avoiding law enforcement detection.
Conspiracy to provide material support carries a maximum penalty of up to twenty years imprisonment and a $250,000 fine. Under terms outlined in the plea agreement, Mirreh will not appeal if sentenced at or below twenty years; likewise, prosecutors agreed not to appeal if such a sentence is imposed.
The Federal Bureau of Investigation is investigating this case. Prosecution is being handled by Assistant United States Attorney Todd Greenberg along with Assistant U.S. Attorney Camila A. Garces from Newark’s National Security Unit and Trial Attorneys John Cella, Patrick Cashman, and James Donnelly from the Department of Justice’s Counterterrorism Section within its National Security Division.
The U.S. Attorney for the Western District of Washington covers areas including Seattle and Tacoma; it operates offices there with about eighty-five attorneys and seventy support staff handling federal prosecutions and civil litigation as part of its mission within the Department of Justice, according to its official website.
