Parkland school shooting 6 years later: Remembering the 17 victims

Seventeen students and staff were killed in the February 2018 Stoneman Douglas massacre.

A 15-year-old Army Junior Reserve Officer Training Corps cadet who dreamed of attending West Point but died helping classmates escape. A precocious 16-year-old girl ready to head to college and "change the world." And a high school football coach who ran toward the sound of gunfire, trying to shield students.

They were among the 17 students and staff shot dead at Marjory Stoneman Douglas High School on Feb. 14, 2018.

Six years after a school shooting that shook the nation, here is a look back at the lives lost in the Parkland, Florida, massacre.

Freshman soccer player Alyssa Alhadeff "took every second of her life and did something with it," her mother, Lori Alhadeff, told ABC News. "She had the fire to fight."

Alyssa Alhadeff was on track to play soccer in college and had dreamed of one day being on the U.S. women's national team, her mother said.
