She also sounds angry at the school, imo.
From your link:
Jolliff said she was horrified to hear that friends of 17-year-old Dylan Butler, who police have identified as the shooter, say he was bullied for years and that teachers and school officials did nothing to protect him.
...Jolliff said she didn’t know anything about Butler’s situation, but had sympathy for him. Jolliff says she hopes that administrators have learned the importance of checking on students to make sure they’re ok.
“I just pray that what we lost isn’t in vain and that other things can be put in place with the school system,” Jolliff said.
