DOUGLAS COUNTY, Kan. (WDAF) – A 9-year-old girl died from her injuries Sunday morning after a white delivery van hit the motorcycle she was riding.

The crash happened on East 1900 Road and Kansas 10 Highway exit ramp.

A 54-year-old man was driving a motorcycle with a 9-year-old girl as his passenger. The man suffered serious but not life-threatening injuries, and the girl, who was wearing a helmet, suffered critical injuries and later died.

“What really strikes at the human nerve for us in the citizens is the fact that a person could be involved in something like this and then leave,” said Douglas County sheriff Jay Armbrister.

The vehicle is missing a black front-end bumper cover and front splash guard, and it likely has sustained front-end damage to the vehicle itself. Investigators also said the van that left the scene is likely a 2013-2019 white Ford Transit Connect XL Model. It is more likely to be believed as a 2018-19 model.

“We also have learned from my witnesses that the vehicle actually accelerated as it left the scene. And then left behind at the scene was the front bumper,” Armbrister said. “There’s a family that is absolutely devastated and deeply grieving, and they deserve to have the answers.”

Anyone with information on the driver’s identity and the vehicle is asked to call 785-843-0250 and reference case number D22-09801.
