(KAIR)--Two go to the hospital, while one vehicle flees the scene, following a three vehicle crash Wednesday afternoon in Atchison County. 

Authorities are seeking the vehicle they say caused the wreck, around 4:00, on U.S. Highway 73, just north of 234th Road. 

The wanted vehicle is described by the Atchison County Sheriff's Office as a black Toyota car that was northbound on the highway, attempting to pass another car without enough clearance. The Toyota drove onto the west shoulder of the road, then swerved back into the correct lane at the last moment, causing a southbound vehicle, driven by 29-year-old Leavenworth resident Richard Olsen, to swerve into the northbound lane. Olsen's vehicle then collided with the one the Toyota was attempting to pass, driven by 55-year-old Leavenworth resident Maria Silvi Aispuro De Navarro. She and a passenger, 53-year-old Santa Prouty, of Leavenworth, were transported by ambulance to the Atchison Hospital. 

Olsen refused treatment by EMS. 

Now the Sheriff's Office is asking for help from the public in locating the Toyota that left the scene. Anyone with information should call 913-367-4323.
