“I never thought I would live across the street from a Columbine,”

John Crescitelli, a doctor with a 15-year-old daughter at the school, learned about the shooting at work. A familiar feeling — empty, hollow — hit him. His brother was a firefighter in New York City during the 9/11 attacks. All those years ago, Crescitelli didn’t know whether his brother was dead. Now he didn’t know about his daughter. The two were eventually reunited.

“I never thought I would live across the street from a Columbine,” he told reporters.

the fire alarm blared through the classrooms and hallways of Marjory Stoneman Douglas High School.
