Honor guards form the Hilliard Division of Police and Norwich Township Fire Department will lead a public memorial ceremony at 7 p.m. Tuesday, Sept. 11, at First Responders Park, at Center and Main streets in Old Hilliard.

Police Chief Bobby Fisher and fire Chief Jeff Warren are scheduled to speak.

The annual ceremony is in memory of the almost 3,000 people killed during the terrorist attacks of Sept. 11, 2001.

Many first responders in New York City were killed after arriving at the two World Trade Center towers, which collapsed shortly after hijacked passenger airplanes were crashed into them; an airplane also was crashed into the Pentagon in Washington, D.C., and a fourth crashed in rural Pennsylvania, short of its intended target, after passengers fought for control of the plane.

First Responders Park has walls engraved with the names of those killed and a steel beam from one of the World Trade Center towers.
