The Parkland high school shooting was over 4 years ago. These are the 17 victims.

Alhadeff was a star soccer player and known for her work volunteering at homeless shelters. She loved her debate class and spending time at the beach. Her friends remembered her for her smarts, kindness, and contagious laugh.

Her mother, Lori Alhadeff, recalled in a recent open letter the moment she learned a shooting had occurred at the high school.

"I knew you were gone," she wrote. "You were with me. I knew it."

Another hero. This is 35-year- old Scott Beigel. He was my son’s friend’s Geography teacher at Marjory Stoneman Douglas High School. Beigel was murdered after letting students take shelter in his classroom & got in the way of the shooter as he tried to enter the class. Beigel saved many lives.

Beigel was a beloved coach, summer-camp counselor, and a first-year geography teacher. He was killed when the Parkland shooting first broke out, as he tried to rush students back into his classroom.

He was known for his sense of humor and the honesty he brought to the cross-country runners he coached.

"As soon as we met Coach Beigel, we knew it was going to be a good year," Alyssa Fletcher told Runner's World.
