A sixth grader at the school, Lucy Long, told Idaho Falls ABC affiliate KIFI
she heard pounding on her classroom's door and then two gunshots,
followed by screams, running in the hallway and a third gunshot that
sounded farther away.
"I was really scared," Lucy told the
station. "I almost started crying, but I was trying to help my other
friends that were crying feel better."
"We were so worried that
someone was going to come in after they were pounding on our door, like
they were going to try to get in and hurt us," she said.
Students were moved to a nearby high
school following the incident, which was caught on the middle school's
security system, the sheriff said.
The name of the student has
not been released. The sheriff said she lives in nearby Idaho Falls and
attended the middle school in Rigby.
Idaho Gov. Brad Little said he was staying updated on the shooting.
"I am praying for the lives and safety of those involved in today's
tragic events," Little said on Twitter. "Thank you to our law
enforcement agencies and school leaders for their efforts in responding
to the incident."
