Hundreds of rescue workers were on the scene Thursday morning – 25 miles northwest of Des Moines. At 7:37 a.m. ambulances, police units, rescue aircraft and firefighters were called to the school.

The Dallas County Sheriff's Office confirmed the shooting, which occurred on the first day of class. The FBI Omaha Des Moines was on scene, as was the Bureau of Alcohol, Tobacco, Firearms and Explosive.

County Sheriff Adam Infante said at an 11 a.m. news conference that police officers arrived at the high school seven minutes after the initial call.

First responders found “multiple gunshot victims” at the school, but Infante said they were still working to confirm the number of victims. He did not confirm whether anyone had died.

WHO 13 and AP said the shooter is believed to have died of a self-inflicted gunshot wound.

Adam Infante said there were few people in the building at the time of the shooting because the school day had not yet started.

Infante said there is no further threat to the community. They have identified the shooter but have not confirmed whether he is alive or deceased.

The sheriff said: “The community is safe.” “We are now working backwards to see what happened.”

Today is the first day back from winter break for the 1,785 students studying in the Perry Community School District.

The number of possible injuries and victims has not yet been confirmed by police, but ABC reports that one person was killed in the shooting.

Carlos, a student at Perry High School, told WHO 13 that he and his friends initially thought the “loud banging noises” were part of a prank – before a teacher started yelling at the students, “Go, go, go.”

He said: “I heard a few bangs, they weren't loud.” We saw a lot of people running away. We thought it was a prank or something. “We didn’t think it was real at first.”

Zander Shelley, 15, was in a hallway waiting for the first day of school to start after recess when he heard gunshots and ran into a classroom, according to his father, Kevin Shelley.

Rachael Kares, an 18-year-old senior, was finishing jazz band practice when she and her bandmates heard what she described as four shots fired apart.

“We all just jumped,” Kares said. “My band teacher looked at us and yelled, 'Run!' So we ran.”

Kares and many others from the school were running past the soccer field when she heard people screaming, 'Get out! Get out!'

She said she heard more gunshots as she ran, but didn't know how many. She was more worried about getting home to her three-year-old son.

“At that moment I didn’t care about anything except getting out because I had to go home with my son,” she said.

Ava Augustus, a senior at Perry High School, burst into tears as she remembered what she saw this morning.

She said: “I'm running and you see glass everywhere, blood on the ground.” “I get to my car and they're pulling a girl out of the audience who's been shot in the leg.”
