It’s been 23 years since the attack on Sept. 11, 2001, and remembrance events are happening all across the country as Americans remember the 2,977 people who lost their lives that day.

In Blue Ash, just north of Cincinnati, the fire department hosted a run and walk to honor one heroic New York firefighter: Stephen Siller.

"Siller heard the radio call for all Fire Department New York firefighters to report for duty after getting off his shift earlier that morning," Blue Ash wrote on its website. "Unable to return to the station, due to the closed Brooklyn-Battery Tunnel, he got out of his personal truck and ran the two-and-a-half miles through the tunnel in his full firefighter’s uniform to the site of the Twin Towers. Stephen Siller was one of many firefighters whose remains were never recovered."

In its fourth year, the Blue Ash Sept. 11 event looked a little different. Typically, first responders in the area would be getting ready to climb the steps of the nearby Observation Tower, but with ongoing construction, they pivoted to a run and walk this year.

Officials also a 21 gun salute, taps and speakers to remember the nearly 3,000 lives lost 23 years ago, including 343 firefighters.
