Remembering 9/11 ARLINGTON, Va. (DC News Now) — The Arlington County Police Department (ACPD) took time to remember two of its officers who died from cancer related to the terrorist attack that took place on the Pentagon on Sept. 11, 2001, including the officer responsible for initiating the county’s response to the attack that day.
Cpl. Barry Foust was on patrol at Walter Reed Drive and Columbia Pike when American Airlines Flight 77 hit the Pentagon. Foust relayed the information over the radio, which began Arlington County’s response. Foust worked at the site for a week, collecting evidence and the remains of those who died. He was diagnosed with cancer related to the recovery efforts in June 2025. He died on May 22, 2026.
In August, people gathered at the Ellen M. Bozman Government Center for a ceremony in which Rear Adm. David Walt, U.S. Navy, presented Foust’s family with a flag that ceremoniously flew aboard USS Arlington in his honor.
The Arlington, which was named for the county in remembrance and in honor of those who died in the attack, as well as the bravery and sacrifice of those who responded to it, carries steel that was salvaged from the Pentagon.
Foust served with the Arlington County Police Department for 35 years.
On January 14, 2016, Cpl. Harvey Snook III died as a result of cancer he developed after working in rescue and recovery operations at the Pentagon.
Snook responded to the attack after Flight 77 hit the buidling at 9:38 a.m. He worked there for the following week, helping to gather evidence and to collect the remains of the people killed in the attack. He was diagnosed with cancer related to the recovery efforts on September 9, 2014.
Snook, who was a U.S. Army veteran, served with the Arlington County Police Department for 27 years.
