A female teacher disarmed the girl and held her until law enforcement arrived and took her into custody, authorities said. They did not provide further details. Authorities said they’re investigating the motive for the attack and where the girl got the gun.
The suspect is from the nearby city of Idaho Falls, Anderson said. He didn’t release her name.
Dr. Michael Lemon, trauma medical director at Eastern Idaho Regional Medical Center, said the injured adult was treated and released for a bullet wound in an extremity. The bullet went cleanly through the limb, he said.
Both of the students who were shot were being held at the hospital overnight, and one of them might need surgery, Lemon said. Still, both students were in fair condition. One of the students had wounds in two limbs and might have been shot twice, he said.
Police were called to the school around 9:15 a.m. after students and staffers heard gunfire. Multiple law enforcement agencies responded, and students were evacuated to a nearby high school to be reunited with their parents.
“Me and my classmate were just in class with our teacher — we were doing work — and then all of a sudden, here was a loud noise and then there were two more loud noises. Then there was screaming,” 12-year-old Yandel Rodriguez said. “Our teacher went to check it out, and he found blood.”
Yandel’s mom, Adela Rodriguez, said they were OK but “still a little shaky” from the shooting as they left the campus.
“Today we had the worst nightmare a school district could encounter,” Jefferson School District Superintendent Chad Martin said.
Martin said schools would be closed districtwide to give students time to be with families, but that counselors would be available starting Friday morning.
Rigby Middle School has about 1,500 students in sixth through eighth grades, according to the National Center for Education Statistics.
“I am praying for the lives and safety of those involved in today’s tragic events,” Governor Brad Little said in a prepared statement. “Thank you to our law enforcement agencies and school leaders for their efforts in responding to the incident.”
Police tape surrounded the middle school, and small evidence markers were placed next to spots of blood on the ground. Investigators interviewed faculty and staffers individually.
Lucy Long, a sixth-grader at Rigby Middle School, told the Post Register newspaper in Idaho Falls that her classroom went into lockdown after they heard gunshots, with lights and computers turned off and students lined up against the wall.
Lucy comforted her friends and began recording on her phone, so police would know what happened if the shooter came in. The audio contained mostly whispers, with one sentence audible: “It’s real,” one student said.
Lucy said she saw blood on the hallway floor when police escorted them out of the classroom.
The attack appears to be Idaho’s second school shooting. In 1999, a student at a high school in Notus fired a shotgun several times. No one was struck by the gunfire, but one student was injured by ricocheting debris from the first shell.
In 1989, a student at Rigby Junior High pulled a gun, threatened a teacher and students, and took a 14-year-old girl hostage, according to a Deseret News report. Police safely rescued the hostage from a nearby church about an hour later and took the teen into custody. No one was shot in that incident.
