NYPD memorial wall dedicated as illness toll from September 11 service surpasses 469 members

The NYPD has lost more than 469 members to illnesses connected to their service after the September 11, 2001 attacks, Police Commissioner Jessica Tisch said during a ceremony this week dedicating a memorial wall at One Police Plaza. The wall honors the 23 officers killed at the World Trade Center that morning, 14 of them from the emergency service unit, alongside members who have since died from related illness. Chief of Department Michael LiPetri added that more than 1,700 members have retired from the department carrying World Trade Center-related disabilities.

LiPetri said the toll is still accumulating. "We are still losing members to illnesses caused by their service after the attacks," he said. "All these years later, we are still standing with families as they bury loved ones whose lives were forever changed by the work they did after Sept. 11." NYPD Chief Chaplain Reverend R. Bernard, speaking at the invocation, was direct about the timeline: "Sept. 11 did not end on Sept. 11. For many, the costs continued for years, illness endured, families impacted and lives ultimately lost."

Mayor Zohran Mamdani drew on the record of Officer John William Perry, who was at One Police Plaza that morning preparing to resign and begin a law career when the first plane struck the North Tower. Perry asked for his shield back and went to the World Trade Center. He was last seen helping a woman out of the South Tower before returning to the building. Perry was among the 23 killed that morning.

Continuity across generations

Tisch noted that thousands of current NYPD officers were children on September 11, and many others had not yet been born. She said preserving the record of those who served is growing more urgent as the generation that responded to the attacks retires. Mamdani pointed to the sons of officers Ronnie Klopfer and Joseph Viviano. Both sons now serve in the department and play on the lacrosse team Klopfer founded before the attacks.

"The faces in this building will be different, but these names will still be here," Tisch said.

LiPetri described the obligation as institutional. "Whatever rank we reach, whatever command we lead, we are standing on the foundations other people built," he said. "We inherit their lessons, their example, and eventually it becomes our responsibility to pass those things forward."
