The mother of a student killed in Wednesday’s shooting massacre at Marjory Stoneman Douglas High School in Parkland, Florida, appeared on CNN to plead for action in the wake of the 18th school shooting  in the U.S. since the new year, though not all of those were mass casualty events like he Parkland massacre.

Lori Alhadeff’s daughter Alyssa Alhadeff, 14, was among 17 people killed after Nikolas Cruz, 19, opened fire in the high school on Wednesday afternoon. On Thursday, the grieving mother gave an emotional, heart-wrenching interview to CNN, pleading for action to prevent future tragedies.

“A gunman, a crazy person just walks right into the school, knocks down the window of my child’s door and starts shooting, shooting her and killing her,” she said on camera.

“President Trump, you say what can you do. You can stop the guns from getting into these children’s hands.”

Alhadeff later said through tears that she had spent the afternoon preparing her daughter’s body for her funeral.

“This is not fair to our families, that our children go to school and have to get killed!”
