Two students are dead after a shooting at a Des Moines, Iowa charter school on Monday afternoon.

Police were called to Starts Right Here school shortly before 1 p.m. local time after multiple 911 callers reported a shooting. Officers found three people suffering gunshot wounds when they arrived on the scene.

Two victims, identified as students, were taken from the scene in “very critical condition.” Police later confirmed that those students died from their injuries at the hospital.

The third injured person, an adult school employee, was taken from the scene in serious condition and was undergoing surgery Monday afternoon.

The names of the shooting victims have not been released.

Roughly 20 minutes after the shooting, police say three people were taken into custody about two miles away from the scene. Authorities were able to track a vehicle to an apartment complex on the south side of Des Moines. Two suspects stayed in the vehicle and were taken into custody. A third person ran from the car but was quickly captured thanks to a police K9 unit. Police have not released the suspects’ names.

“The incident was definitely targeted. It was not random. There was nothing random about this,” Sgt. Paul Parizek said.
