The names of all 2,996 victims were read outside an Oswego church, and Dwayne Collman read the names of flight 11 crew members, including his son.

“He’s just a missing part of our life. We have other kids and we love them a whole lot, but that doesn’t make up for one that’s missing,” his mother, Kay Collman, said.

Remembering the missing was the theme of the day. Along Washington Street in the center of town, volunteers mounted a display of almost 3,000 pairs of shoes – one for each victim of the attacks.

“Seeing all these empty shoes really brings home the understanding of how many lives were so needlessly lost that day for everybody,” Yorkville resident John Etheridge said.
