ALPINE, Texas (AP) — Investigators have concluded that a 14-year-old female freshman who shot and wounded a fellow student at a West Texas high school before killing herself had planned to shoot her 14-year-old stepbrother before shooting herself.

In a statement issued Tuesday, Chief Russell Scown of the Alpine Police Department says the girl's plan was foiled when a 17-year-old junior walked into the girls' restroom at Alpine High School where the freshman girl was arming herself Thursday. The shooter, whom police haven't identified, aimed her gun at the older girl, who ducked and began running when she was shot in the lower body. Officials said that day that the wound was not life-threatening.

The freshman then shot and killed herself. Police say no others at the school were targeted.
