Tens of thousands gathered at a "March for Our Lives" rally in New York City on Saturday held a moment of silence to honor 17 people killed during a school shooting in Florida just last month.
Sam Hendler, a 16-year-old student from Marjory Stoneman Douglas High School in Parkland, Florida, was at the rally to read the victims' names.
Another MSD student, Meghan Bonner, told the demonstrators that she wasn't surprised when she learned the identity of the shooter because it was obvious something was wrong with him.
"There was so much more that could have been done to prevent this," she said, fighting back tears. "I want to see change."
The rally in midtown Manhattan is one of several being held across the United States on Saturday in response to gun violence.
