An Idaho teacher who disarmed a sixth grader after she opened fire at school earlier this month is breaking her silence for the first time. Krista Gneiting, a math teacher at Rigby Middle School in the small town of Rigby, about 15 miles northeast of Idaho Falls, was preparing her students for their final exams on the morning of May 6 when she said she heard a gunshot from down the hall. She said she looked outside her classroom and saw the school's janitor lying on the floor at the end of the hallway. She said she shut the door as she heard two more gunshots. "So I just told my students, 'We are going to leave, we're going to run to the high school, you're going to run hard, you're not going to look back and now is the time to get up and go,'" Gneiting recalled during an exclusive interview with ABC News that aired Wednesday on "Good Morning America." A sixth grade student at the school had taken a handgun from her backpack and opened fire just before 9 a.m. local time, wounding two students and one adult, according to the Jefferson County Sheriff's Office. The girl shot two of the victims in the hallway before moving outside and shooting the third victim, the sheriff's office said. All three victims were expected to survive.
