OMAHA, Neb. (AP) — Swim classes at Nathan Hale Magnet Middle School in Omaha have been halted in the wake of the drowning of a 12-year-old boy in the school’s pool last week.

10 students were being supervised by one teacher in the gym aquatics class on Nov. 13, when seventh-grader Demariont’e Brown-Elliott was pulled from the pool.

Omaha Public Schools spokesman Todd Andrews says that in lieu of swimming, Nathan Hale students have been doing other activities in gym class this week. Andrews says swim classes have continued at other district schools with pools.

The school district and police are conducting investigations into the boy’s death.
