A female student at Alpine High School in Alpine, Texas, is dead after she shot and injured a fellow classmate only to turn the gun on herself shortly after. 

An officer on the scene was also injured by friendly fire from an "accidental discharge" after arriving at the scene of the crime. As of now, it appears that the shooter is the only death in this latest tragic school shooting.

When police first arrived at the high school, they believed there may have been two active shooters, but shortly after finding the shooter's dead body, they called off the search for a second assailant.

The shooter had “one self-inflicted gunshot wound” and is deceased, Brewster County Sherrif Ronny Dodson explained. Adding, “It looks like she [the shooter] shot another individual, and that individual had run out into the street."

An Alpine High junior spoke to CNN to describe the moments of terror. The unnamed student explained that second period had just began when a teacher outside her class yelled, "Get in the classroom!" She added, "My teacher ... yelled to everyone to get into the closet." Moments later "we heard someone yelling and running down the hall. We all started crying."

The junior continued, saying that after police began ushering students out "there was blood on the floor in the cafeteria that I saw when we went past it on our way out of the school," the student said. Adding, "One of the officers told us to keep our hands up and run out of the building, so I only saw the blood quickly."

NewWest9 was on the scene of the crime and offered as much information about the horrifying incident:

A spokesperson for Big Bend Regional Medical Center told Buzzfeed that they are treating the two injured individuals, though there is no word on how critical the victims' injuries are.
