She lost her daughter in Parkland. Now she's fighting for school safety.

PARKLAND, Florida — A year ago, Lori Alhadeff was a soccer mom with three kids in the Parkland, Florida, public schools.

But on February 14, that simple life was shattered in a hail of bullets fired by a shooter at Marjory Stoneman Douglas High School. Lori's daughter, Alyssa, was among the 17 who died that day.

The year after has been one of pain and healing and hope for Lori. She became the face of anguish when a CNN camera captured her grief and the clip went viral. Now she's trying to become the face of school safety as an advocate and elected member of the Broward County School Board.

Across the country, schools are still trying to figure out how to prevent the next Parkland. Bills have been passed, experts have weighed in. School boards like the one in Broward are still making changes. VICE News followed Lori as she tries to make school safety a public priority.

"People would say to me that we need to fix this, and I realized right away that what they were really saying is, 'I can't do it. You have to do it'," Lori told VICE News.
