It was believed that on the morning of September 11, 2001, while on the way to work at Rockefeller University, Hamdani witnessed the smoke coming from the Twin Towers and hurried to the scene to aid victims, using his police and EMT identification to get a ride through the restricted traffic. Hamdani was reported as missing; his family feared he had gone to the World Trade Center in an attempt to help as an EMT, but held out hope he was being secretly held by the government because of his religion. His mother wrote to President
George W. Bush to plead for his help. In the weeks following the attack, investigators from the FBI and NYPD began questioning the family about Hamdani. His mother said
US Representative Gary Ackerman, whose
congressional district included Queens, was among the officials who came to the family's Bayside home to ask questions about her son, including what his motives were for becoming a police cadet, which Internet chat rooms he visited and why he had been in London. According to the family, CIA officials came to help find their missing son. They confiscated a college graduation photo of Hamdani posing with a student from Afghanistan. In October 2001, remains of a body, along with Hamdani's medical bag and identification, were found in the wreckage of the North Tower at
Ground Zero. He was cited in the USA PATRIOT Act, signed into law on October 26, 2001, in
Title 1, section 102: Hamdani's remains were positively identified through a
DNA match in March 2002. ==Legacy==
