In the confusion that followed, numerous law enforcement officers rushed to the scene and a US marshal accidentally shot a Homeland Security agent, Brewster County Sheriff Ronny Dodson said.
Dodson said the agent was in stable condition; he didn't release the condition of the wounded student. Her injuries didn't appear to be life-threatening.
Dodson said the student who died moved about six months ago to Alpine, a community of about 6,500 people roughly 200 miles southeast of El Paso. Dodson didn't identify her or provide a motive but said her family is cooperating.
