What we know so far about the Comal County high school shooting

KSAT is following through on our push to learn more about the student who investigators say shot a teacher and then killed himself. That shooting happened before class began yesterday at Hill Country Preparatory High School near Bulverde. KSAT Investigates Daniela Ibarra has been covering violence against educators for years. She spoke with the Comal County Sheriff this afternoon about what they've learned so far.
