Two decades after 9/11, federal investigators earlier this year formally closed their investigation into three Saudi nationals suspected of helping two hijackers prior to the attacks, according to a previously classified FBI document released by the Justice Department Thursday.

The three men were identified as Fahad Al-Thumairy, Omar Al-Bayoumi, and Musaed Al-Jarrah. According to the document, they allegedly provided or directed others to provide Nawaf al-Hazmi and Khalid al-Mihdhar with “assistance in daily activities, including procuring living quarters and assistance with assimilating into Southern California.”

Prior to closing the investigation on May 27, the FBI says it re-examined the case file in 2019 and 2020 “to identify any missed leads, opportunities, or investigative actions which may advance the case.” 

Alan Chin was near the site of the collapsing World Trade Center towers, taking photos as dust swirled through the air. He shares the stories behind some of his powerful images from that day.
