BOSTON, MA -- Three years ago, three people were killed and over 260 injured when two bombs detonated at the Boston Marathon. Now, the city is paying homage to those affected by the bombings through a day of service and kindness known as One Boston Day.
Mayor Marty Walsh and Massachusetts Governor Charlie Baker joined with families for a wreath laying ceremony on Boylston Street in Boston, near the marathon finish line. There will also be a moment of silence across the city at 2:49 p.m., the time when the first bomb was detonated.
"Just as the world has repeatedly demonstrated after the horrors of San Bernardino, Paris, Brussels, and elsewhere, the people of Boston showed that bombs and bullets cannot break our spirit -- that freedom will ultimately overcome fear," Lisa O. Monaco, Assistant to the President for Homeland Security and Counterterrorism, said in a statement. "As we relentlessly pursue these terrorists and counter their destructive ideology, we continue to draw inspiration from a city that has shown the true meaning of Boston Strong."
Rebekah Gregory, a victim who lost her leg in the bombings, wrote a thoughtful note on Facebook, describing how her life has changed since the tragic events three years ago. "When life hands us something of this kind of magnitude, it changes every fiber of our being. And we can never go back to the way we were before, no matter how much we may want to at times," Gregory wrote in her post.
People across the city will also be taking part in blood drives, food and clothing donations and other community service projects to pay tribute to Boston and those affected marathon bombings. See how some are giving back for One Boston Day below:
