WASHINGTON – Mustafa al-Imam, a Libyan national approximately 48 years old, was found guilty of terrorism charges for his participation in the Sept. 11, 2012, attack on the U.S. Special Mission and Annex in Benghazi, Libya. Ambassador J. Christopher Stevens and U.S. government personnel Sean Smith, Tyrone Woods and Glen Doherty died in the attack at the Mission and the nearby CIA Annex in Benghazi.

           The announcement was made by Assistant Attorney General for National Security John C. Demers, U.S. Attorney for the District of Columbia Jessie K. Liu, Assistant Director Michael McGarrity of the FBI’s Counterterrorism Division., and Assistant Director in Charge William F. Sweeney, Jr. of the FBI’s New York Field Office.

           “We will never forget those we lost in Benghazi on Sept. 11, 2012 – Tyrone Woods, Sean Smith, Glen Doherty, and Ambassador Christopher Stevens,” said Assistant Attorney General Demers.  “And we will not rest in our pursuit of the terrorists who attacked our facilities and killed these four courageous Americans – they must be held accountable for their crimes.  I want to thank the agents, analysts, and prosecutors – and all of their partners in the U.S. government – who are responsible for this important investigation.”

           “Mustafa al-Imam was found guilty and will be held accountable for his role in the terrorist attack that destroyed the U.S. Mission in Benghazi,” said U.S. Attorney Liu.  “Four American heroes lost their lives and others were seriously wounded during the attack on two U.S. facilities. We will continue to work with our law enforcement partners to pursue justice against those who commit terrorist acts against the United States no matter how far we must go or how long it takes.”

           “Mustafa Al-Imam has been found guilty for his role in a brutal terrorist attack on U.S. diplomatic facilities in Benghazi that killed four Americans,” said Assistant Director Michael McGarrity. This case shows the FBI's commitment to bring to justice those who commit acts of terror against the United States and our citizens—no matter how far away those acts take place or how long an investigation may take.”

           “Mustafa al-Imam played a significant role in the 2012 Benghazi attack, one that ultimately claimed American lives,” said Assistant Director William F. Sweeney, Jr. “While nothing will ever change the outcome of this horrific event, today’s verdict is a reminder that the safety of Americans—whether at home or abroad, civilian or otherwise—will always be our top priority. If you commit an act of terrorism, we will find you and bring you to justice."

           Al-Imam was captured in Libya on October 29, 2017. He was found guilty by jury on June 13, 2019, of conspiracy to provide material support and resources to terrorists and maliciously destroying and injuring a dwelling and placing lives in jeopardy.  The former charge is punishable by up to a maximum of 15 years in prison, while the latter charge is punishable by up to a maximum of 20 years in prison.  The jury failed to reach a verdict on 15 other charged counts, leading the court to declare a mistrial on those counts today, June 17, 2019.  The government has not yet announced whether it plans to retry Al-Imam on the remaining counts. The maximum statutory sentences are prescribed by Congress and are provided here for informational purposes.  The sentencing of the defendant will be determined by the court after considering the advisory Sentencing Guidelines and other statutory factors.

           The trial began with opening statements on May 8, 2019, before a jury in the courtroom of the Honorable Judge Christopher R. Cooper of the U.S. District Court for the District of Columbia. Over the next four weeks, the government presented testimony from 29 witnesses. The witnesses included those who were wounded in the attack, as well as others who survived the attacks.

            This case was investigated by the FBI’s New York Field Office with substantial assistance from various other government agencies, including the Department of Defense and the two victim agencies, the CIA and the Department of State. The National Security Division’s Counterterrorism Section provided significant assistance.

           The case was prosecuted by Assistant U.S. Attorneys John Cummings and Karen Seifert of the National Security Section of the U.S. Attorney’s Office for the District of Columbia.  Assistance was provided by Assistant U.S. Attorneys Nicholas Coleman and Jolie Zimmerman, Paralegal Specialist Donna Galindo, detailed Paralegal Specialist Ashley Davis, Intelligence Research Special Dustin Powell, contract Document Management Analyst Michael Watts, Victim-Witness Advocates Yvonne Bryant, Tonya Jones, Laverne Perry and Wanda Queen, and Litigation Technology Chief Leif Hickling.  Earlier stages of the prosecution were handled by Assistant U.S. Attorney Michael DiLorenzo and former Assistant U.S. Attorneys Opher Shweiki and Julieanne Himelstein.
