(KMZA)--Nine people were injured in a two-vehicle crash Friday afternoon in Nemaha County.

The Kansas Highway Patrol says the crash happened on U.S. 36 Highway, about one mile east of K-236, shortly after 4:00.

The Patrol reports 71-year-old Timothy Wanklyn, of Frankfort, was westbound when, for an unknown reason, his pickup truck drifted left of center and went head-on with an eastbound van. 

Wanklyn and a passenger, 25-year-old Cody Wanklyn, of Frankfort, were both transported to the Nemaha Valley Community, in Seneca, with suspected serious injuries.

The Patrol says both were wearing seat belts.

The driver of the van, 28-year-old Gilver Caceres, of Topeka, and six passengers, also from Topeka, were transported to three local hospitals--six with suspected serious injuries and one with suspected minor injuries.

The Patrol says four other passengers in the van left the scene of crash. Their injury status is unknown.
