Jackie was one of 19 children and two teachers killed in the Robb Elementary School shooting on May 24, 2022, in Uvalde, Texas. A unicorn and a cursive "J" are painted on her purple walls, which also display a sticker that says "It's okay not to be okay." An "About Me" chalkboard on the floor proclaims her favorite movie, "The Nightmare Before Christmas," and her top song, Olivia Rodrigo's "favorite crime."
