ARGOS, Ind. – A child died Wednesday morning after a crash involving a school bus and a truck near Argos, Indiana. Police said the students were on a field trip to see “Elf The Musical” in Warsaw, WBND reports.

Indiana State Police troopers were dispatched just after 9:05 a.m. the scene of the crash, Sgt. Ted Bohner said Wednesday. The collision occurred at the intersection of northbound US 31 and a set of railroad tracks just south of SR 10.

There were 39 students on the bus, which was from Eastern Pulaski schools.

One of those students died in the crash. Authorities have not released the child’s identity. The student’s family was notified.

Another student was airlifted to a hospital in South Bend. That child’s injuries were not life-threatening.

The other 37 children were transported to St. Joseph Regional Medical Center in Plymouth to get checked out and reunite with their families.

Police have not yet released any information about the bus driver, the driver of the truck or any adults that were on board the bus.

The bus was not traveling at highway speed when the crash occurred, Bohner said. Investigators are working to determine whether the bus driver had stopped at the intersection to check for a train, was slowing down or speeding up when the bus and the truck collided.

It is unclear whether weather was a factor in the crash. Bohner said the area saw bad weather earlier on Wednesday.

The investigation is ongoing.
