COUNCIL BLUFFS, Iowa (AP) — The Council Bluffs community has come together to remember a western Iowa 17-year-old who died from a head injury suffered during a fight at school.

Friends of Dakota Escritt released balloons at a memorial Sunday night. He died Saturday at Children’s Hospital and Medical Center in Omaha, two days after he hit his head on the tile floor at Abraham Lincoln High School.

Authorities have filed an assault charge against a 16-year-old boy, who was suspended from school. The Associated Press generally does not identify juveniles accused of crimes.

Superintendent Martha Bruckner tells KETV-TV the fight appeared to be a random, isolated incident that no policy could have prevented.
