The tragedy left searing memories in the minds of parents, who waited anxiously to hear if their child survived; teachers, who heroically tried to protect students; and teenagers who lost some of their best friends.

Since then, there have been more mass shootings around the nation. Last month, eleven people died in a Pittsburgh synagogue. This month, twelve people died in a California bar.

More people, like Parkland’s Lori Alhadeff, the mother of 14-year-old Alyssa Alhadeff, have buried their loved ones.

The heart-wrenching crime in Parkland gripped the nation, and its aftermath saw the creation of a movement to change gun laws that started by some of the young survivors. They have since registered people across America to vote.
