ALPINE, Texas (AP) — A sheriff says a student has died of an apparent self-inflicted gunshot wound after shooting and injuring another student at a West Texas high school.

Brewster County Sheriff Ronny Dodson tells a radio station (KVLF) that a female student shot another female student inside Alpine High School today.

The injured student was taken to a hospital with injuries that weren’t considered life threatening.

The sheriff says a federal law enforcement officer responding to the shooting was shot in the leg when another officer’s gun accidentally went off.

Sheriff Ronny Dodson said the Thursday morning shooting at Alpine High School was part of a chaotic series of events that included a bomb threat at nearby Sul Ross State University. The sheriff said the threat was later deemed a hoax, but that it required officers to rush to the university from the high school.

Dodson says, “That’s ridiculous for someone to call in something like this when we’ve got this situation going on.” The university says the campus was being cleared by law enforcement.
