Classes have been cancelled at Hill Country College Preparatory High School in Bulverde, Texas, following a school shooting that left a 15-year-old boy with a gun and self-inflicted himself. The teacher was taken to a nearby hospital and her condition is unknown. The small campus of roughly 250 students was placed on lockdown shortly after 8:30 a.m. The sheriff is investigating the student's relationship with the teacher and how the firearm was obtained. The school was evacuated and students were relocated to a local middle school. Despite classes being cancelled, counselors will be available for students and families.
