How did Stephen Siller Jr. spend his Father’s Day? Hauling around a nearly 17,000-pound beam, remnants of the World Trade Center, to honor his father, Stephen Siller Sr., a New York City firefighter who died on 9/11 racing in to rescue victims following the deadliest terrorist attack in American history. Siller’s remains were never recovered from the Ground Zero rubble, 1.6 million tons of twisted steel and concrete. After learning about the attacks, Siller ran two miles through the Brooklyn-Battery Tunnel with 80 pounds of gear on his back to the South Tower. Siller Jr., 25, was only 9 months old when his father was killed on 9/11. But he’s committed to keeping his dad’s memory alive, and the lives of thousands of victims who died on that fateful day, by hauling a 16,900-pound, 21-foot beam from the South Tower on a cross-country tour to commemorate the 25th anniversary of the 9/11 attacks. “My father’s body was never recovered, so who he is is ingrained in that steel,” Siller Jr. told the New York Post.
