Ten years and one day after 20 of her Sandy Hook Elementary schoolmates were killed in the nation’s deadliest school shooting, Nicole Melchionno, now 17 years old, was seated before members of Congress in the wake of another massacre.
Ms Melchionno was a seven-year-old second-grade student at Sandy Hook Elementary School on 14 December, 2012, sitting on the carpet with her classmates and awaiting the day’s lessons from her teacher, when she heard “what sounded like large metal pans being smashed together” down the hall.
