Two New Jersey Men and a Washington Man Plead Guilty to Terrorism-Related Offenses for Supporting ISIS

NEWARK, N.J. - Two men from Montclair, New Jersey and a man from Kent, Washington admitted to charges related to supporting the Islamic State of Iraq and al Sham ("ISIS"), U.S. Attorney Robert Frazer announced.

Tomas-Kaan Jimenez-Guzel, 19, and Milo Sedarat, 21, both of Montclair, New Jersey, pleaded guilty on July 27, 2026 and July 28, 2026, respectively, before U.S. District Judge Katharine S. Hayden in Newark federal court to terrorism-related offenses. Jimenez-Guzel pleaded guilty to an Information charging him with conspiracy to provide material support to a designated foreign terrorist organization, and Sedarat pleaded guilty to an Information charging him with concealment of material support and resources to a designated foreign terrorist organization.

Additionally, Saed Ali Mirreh, 20, of Kent, Washington pleaded guilty on July 22, 2026, before U.S. District Judge Richard A. Jones in U.S. District Court in Seattle, Washington to an Information charging him with conspiracy to provide material support to a designated foreign terrorist organization. Mirreh was originally charged with the conspiracy in the District of New Jersey and consented to have his case transferred to the Western District of Washington for purposes of pleading guilty.

"Any individual supporting ISIS or other terrorist organizations, regardless of whether it involves organizing an attack, planning to travel overseas, or funding others to join ISIS will be investigated swiftly and prosecuted. Jimenez-Guzel and Mirreh planned to travel abroad to actively fight with ISIS, and Sedarat surreptitiously provided funding for those plans. This Office is committed to disrupting foreign terrorist organizations, preventing ISIS-inspired terrorism, and holding accountable those individuals who support terrorist organizations."

- U.S. Attorney Robert Frazer

"These men actively plotted and planned to go overseas to fight with ISIS, one of the worst terrorist organizations responsible for unspeakable violence all over the world. FBI Newark Joint Terrorism Task Force and our law enforcement partners thwarted their plans and stopped Jimenez-Guzel as he arrived at the airport. Regardless of the intent to either fight overseas or plot an attack on our soil - we will tenaciously investigate and arrest anyone supporting and conspiring with terrorists," said Stefanie Roddy, Special Agent in Charge of the FBI Newark.

According to documents filed in the cases and statements made in court:

From July 24, 2025 to November 4, 2025, through communications on encrypted messaging applications, Jimenez-Guzel, Mirreh, and other co-conspirators agreed to travel to Turkey in November 2025. They also agreed with other co-conspirators to travel from Turkey to "sham," which is an Arabic term for the historical region of greater Syria, to join ISIS as fighters. On October 18, 2025, Sedarat met with Jimenez-Guzel and provided him $500 in cash to assist with buying a plane ticket for Mirreh to travel to join ISIS as part of the conspiracy. Sedarat took steps to conceal that monetary transfer from law enforcement by instructing Jimenez-Guzel to not take his cell phone to the meeting where the money was exchanged and by deliberately using cash instead of other electronic money transfers. On October 26, 2025, Jimenez-Guzel then transferred $500 to Mirreh.

On October 27, 2025, Jimenez-Guzel purchased a plane ticket to depart from Newark Liberty International Airport to Istanbul, Turkey on November 17, 2025. On October 28, 2025, Mirreh purchased a ticket to depart from Seattle-Tacoma International Airport to Istanbul, Turkey on November 16, 2025. After other individuals in Dearborn, Michigan, with whom Jimenez-Guzel and Mirreh were communicating were arrested on October 31, 2025, and charged with offenses related to those individuals' plot to carry out a violent attack on behalf of ISIS, Jimenez-Guzel, Mirreh, and their co-conspirators accelerated their travel plans.

On November 3, 2025, Jimenez-Guzel re-booked his flight to Turkey to leave instead on November 5, 2025 (in the early morning hours, shortly after midnight on November 4, 2025). Then, on November 4, 2025, after communicating with Jimenez-Guzel and other co-conspirators, Mirreh booked an additional flight to Turkey to depart on November 5, 2025. On November 4, 2025, Jimenez-Guzel was arrested after arriving at Newark Liberty International Airport, and Mirreh was arrested later that evening at his home in Washington.

The count of conspiracy to provide material support to a designated foreign terrorist organization to which Jimenez-Guzel and Mirreh pleaded guilty carries a maximum penalty of 20 years' imprisonment, a $250,000 fine, and a term of life of supervised release. The charge of concealing material support to which Sedarat pleaded guilty carries a maximum potential penalty of 10 years in prison and a fine of up to $250,000, and a term of life of supervised release. Mirreh's sentencing is scheduled for October 16, 2026, Sedarat's sentencing is scheduled for December 2, 2026, and Jimenez-Guzel's sentencing is scheduled for December 3, 2026.

U.S. Attorney Frazer credited Special Agents and Joint Terrorism Task Force Officers of the Federal Bureau of Investigation, under the direction of Special Agent in Charge Stefanie Roddy in Newark, New Jersey and Special Agent in Charge W. Mike Herrington in Seattle, Washington; and officers of the New York Police Department, under the direction of Commissioner Jessica S. Tisch, Montclair Police Department, under the direction of Chief Todd M. Conforti, and Rowan University Police Department, under the direction of Chief Rachel Baum.

Garces of the National Security Unit in Newark, New Jersey with assistance from Assistant U.S. Attorney Todd Greenberg of the National Security Unit in Seattle, Washington. The government is represented in the case against Sedarat by Assistant U.S. Attorney Casey S. Smith of the National Security Unit in Newark, New Jersey.
