the debris, and many victims and first responders did not wear respirators. It was reported in 2018 that at least 15 FBI agents had died from cancer due to their roles in the aftermath and investigation of the attack. Further, a medical director of the World Trade Center Health Program at Mount Sinai Hospital reported in 2018 that out of the approximately 10,000 first responders and others who were at Ground Zero and have developed cancer as a result, more than 2,000 have died due to 9/11 related illnesses. The Uniformed Firefighters Association of Greater New York also reported over 170 deaths of firefighters due to 9/11-related illnesses, and that roughly 1 in 8 firefighters who were at Ground Zero have developed cancer. At least 221 policemen have died in the years since 2001 from illnesses related to the attacks in New York City. In 2020, the NYPD confirmed that 247 NYPD police officers had died due to 9/11-related illnesses. In September 2022, the FDNY confirmed that the total number of firefighters that died due to 9/11-related illnesses was 299. Both agencies believe that the death toll will rise dramatically in the coming years. The Port Authority of New York and New Jersey Police Department (PAPD), which is the law enforcement agency which has jurisdiction over the World Trade Center due to the Port Authority of New York and New Jersey owning the site, has confirmed that four of its police officers have died of 9/11-related illnesses. The chief of the PAPD at the time, Joseph Morris, made sure that industrial-grade respirators were provided to all PAPD police officers within 48 hours and decided that the same 30 to 40 police officers would be stationed at the World Trade Center pile, drastically lowering the number of total PAPD personnel who would be exposed to the air. The FDNY and NYPD had rotated hundreds, if not thousands, of different personnel from all over New York City to the pile which exposed so many of them to dust that would give them cancer or other diseases years or decades later. Also, they weren't given adequate respirators and breathing equipment that could have prevented future diseases. Forensic identification Identifications through DNA can be made by comparing the DNA profile of reference samples with those found in the human remains, through obtaining samples from personal items (toothbrush/hairbrush), banked biological samples, relatives, or other identified
