At least one person was killed and 2 injured following shooting outside of an Iowa high school

• One person has died and two others injured in a school shooting in Iowa, according to police.
• The shooting appeared to have been a drive-by, police say. Authorities have detained multiple suspects.

One person has died and two remain in critical condition Monday following a shooting outside of a high school in Des Moines, Iowa, local police said in a press release.

The Des Moines Police Department said the incident occurred just after 2:45 p.m. local time at East High School in Des Moines, and that the gunfire appeared to come from a passing vehicle.

Multiple suspects are now in police custody, but charges have not yet been filed, according to the police department.

"We know that the kids in that school are our community's most precious cargo," Des Moines Police Sergeant Paul Parizek said during a news conference after the shooting. "It's sad, but we do train for this. We have to be prepared for it, and this is why."

Superintendent Thomas Ahart said in a statement that "we live in an era when shootings in and near schools have become too common."

"It's unfortunate that our state and our country have become a place where firearms are far too easily accessible," Ahart said. "We remain committed to protecting our students and staff, but real change to gun laws and access would go a long way to help us."

"East High School" was trending on Twitter Monday evening.

"When I see East High School my first thoughts shouldn't be 'another shooting?'" one user tweeted.

Another echoed the sentiment, saying it "desensitizes" children to violence.
