This week, 156 names will be added to the memorial walls in a Nesconset, NY, park, bringing the total number of first responders who died from illnesses linked to their work at Ground Zero to more than 850, according to John Feal, a 9/11 first responder and president of the FealGood Foundation.

The three walls inside the 9/11 Responders Remembered Park were erected to honor their service.

“I find solace that those names are etched and they’ll be there forever,” Wilson said. “But at the same time, I find it disturbing that it’s just growing and growing.”
