LOGANSPORT, Ind. — A special-needs school bus collided with two dump trucks on Friday, fatally injuring four elementary school children.

Indiana State Police said the accident began on a local highway after a motor scooter stopped or slowed to make a turn. A dump truck traveling behind the scooter applied its brakes and veered into opposing traffic, where it struck the left rear portion of the Twin Lakes School Corp. bus.

The bus then overturned and slid into the path of another dump truck, which struck the bus’ roof.

All four children on the bus were pronounced dead at the scene. The bus driver, Deborah DuVall, was injured and taken by helicopter to a hospital. The other drivers were not injured.

An Indiana State Police news release said the crash investigation revealed that all four children and the bus driver were restrained with a seat belt or child safety seat. “The impact was too severe for the restraints to save the children,” the release said.

The children were identified as Trevor Ingram, 10; Lauren Melin, 5; Tyler Geiger, 10; and Kale Seabolt, 9.

A community memorial service was held Monday evening at Twin Lakes High School, and a fund was established to benefit the children’s families.

On the school district Website, visitors posted their condolences. Among them was Ray Lundy, transportation director at Mooresville Consolidated School Corp., outside of Indianapolis.

“Our thoughts and prayers are with all of the parents, drivers and administration,” Lundy wrote on Monday. “This morning, all my drivers joined hands after our bus routes and prayed for God to touch each and every one through these tough times.”
