Victims of terrorism honored every year on this date, killed by a bomb at the World Trade Center in 1993.

Stephen and Nicole Rossilli embrace this chance to honor their grandfather, who they never met. Stephen Knapp, the chief mechanical engineer of the World Trade Center.

“Of course, I wish I would of got to meet him. You know it’s a tragedy what happened, but at least we hear the stories and we do get to keep his memory alive and that’s what matters,” Nicole Rossilli said.

Knapp died 31 years ago — the first-time terrorists attacked the World Trade Center.

“We get to hear lots of stories, especially on about all his fishing trips. He had a boat, and he loved to go fishing. So, we’ve always been told that if he was still around today, we’d all be on a boat every Sunday fishing,” she said.

Just after noon on Feb. 26, 1993, a bomb exploded in the parking garage of the World Trade Center, instantly killing six employees and an unborn child. Secretary Monica Rodriquez Smith, 35, was set to begin maternity leave the following day.

Each year, the Port Authority of New York and New Jersey and the 9/11 Memorial and Museum hold a special ceremony for the victims.

“As we mark the passage of 31 years, this date remains etched in our memories and this attack continues to shake our world,” Elizabeth Hillman, president and CEO of the 9/11 Memorial and Museum, said at the ceremony.

The names of those victims are etched besides the names of those who died on 9/11 at the memorial. Family members and survivors of that day place flowers on their names.

The Rossilli’s said the decades gone by don’t diminish the loss felt at home.

“I feel saddened to see all the lives that were taken, but I’m also happy that they’re keeping all their memories alive. No one deserves to be forgotten,” Stephen Rossilli said.
