(KNZA)--A St. Joseph man was among two people killed in a late Sunday morning crash in northwest Missouri.

The Missouri State Highway Patrol says the crash happened just before noon on U.S. 36 Highway at Missouri Route 33, about two miles west of Osborn in DeKalb County.

The Patrol reports a Saturn Aura, driven by a 42-year-old woman from Chillicothe, was traveling eastbound on U.S. 36 when it struck the towed unit of a northbound Peterbilt semi-truck.

The Patrol says the driver of the Saturn and her passenger, a 43-year-old man from St. Joseph, Missouri were both pronounced dead at the scene. The semi driver, who is from Washington state, was not injured.

It's not known if the victims were wearing seat belts at the time of the crash.

The Missouri State Highway Patrol no longer releases the names of crash victims.
