ROSWELL, N.M. (AP) — A witness says the gunman in a school shooting in the southeastern New Mexico city of Roswell was a student.

The shooter wounded two students at Berrendo Middle School on Tuesday morning before being taken into custody.

Officials at University Medical Center in Lubbock, Texas, say a 14-year-old boy was flown there in critical condition, and a 13-year-old girl was en route in serious condition. Hospital spokesman Eric Finley says information from nurses treating the boy indicates he was the shooter's target.

A student who witnessed the shooting says the shooter was a boy who she thought was being bullied. Eighth grader Odiee Carranza says it happened in the school gym. She says the boy shot the 14-year-old twice in the face, and shot the girl in the arm.

Carranza says the boy then fired a shot into the sky before dropping the gun. A teacher then grabbed him.
