(KNZA)--One Jackson County injury accident leads to another, as a deputy’s patrol vehicle is struck while he’s assisting at the scene.

Jackson County Sheriff Tim Morse, in a news release, said the first wreck happened around 1:00 Sunday afternoon, north of 198th Road, on U.S. Highway 75.

It happened when a northbound pickup truck merged from the passing lane into the northbound driving lane occupied by a semi-tractor trailer.

The pickup truck, driven by 33-year-old Michelle Holmes, of Council Bluffs, Iowa, struck the front of the tractor.

Holmes was transported by Jackson County EMS to the Holton Community Hospital for the treatment of what Morse identified as non-life-threatening injuries.

A deputy, on the scene investigating the crash, spotted a northbound car heading towards the patrol vehicle, and warned the semi driver, who was outside his vehicle, to take cover.

The car, driven by 17-year-old Emily Howard, of Topeka, struck the patrol vehicle, leading to non-life-threatening injuries for Howard.

She was transported by Jackson County EMS to the Holton Community Hospital for treatment.

The deputy, the semi driver, 40-year-old Ryan Love, of Clarksville, Tennessee, and others at the scene, were not hurt.

The Kansas Highway Patrol is investigating the crash involving the patrol vehicle.
