1 child dead, 1 hospitalized after ‘medical incident’ on Johnson County highway

The Johnson County Sheriff’s Office is investigating a “medical incident” on K-10 highway that left a child dead on Wednesday evening, the agency said.

Details surrounding the episode were initially sparse. The Johnson County Sheriff’s Office said in a news release that an adult and two children were inside a vehicle when the “medical incident” occurred, near the K-10 highway-Kill Creek Road interchange around 5:30 p.m. One of the children was pronounced dead at the scene, and the other was taken to a hospital, authorities said.

The “medical incident” happened — on the highway inside the vehicle — to the child who was pronounced dead, said McKenzi Davis, a spokeswoman for the sheriff’s office. The condition of the child who was taken to a hospital was not immediately known. The adult was OK, Davis said.

The event was not a crash, according to Davis, but the Johnson County Sheriff’s Office has not yet said what the medical incident entailed.

Traffic was slowed in the area while first-responders worked at the scene.

“The sheriff’s office is actively investigating the circumstances surrounding this incident,” the sheriff’s office said. “Additional information will be provided as it becomes available.”
