A 70-year-old Washington man was killed in a rollover crash on Interstate 90 southeast of Buffalo late Wednesday afternoon.

It happened around 4:50 p.m. near milepost 74.

The Wyoming Highway Patrol says a pickup driver was descending a grade when the camper she was pulling started swaying side-to-side.

The woman lost control of the combination, and the pickup ended up rolling down a very steep embankment to the bottom of a deep ravine.

During the roll, the passenger side of the cab was pushed down and the passenger, Steven Marshall, suffered fatal injuries to his head and neck.

The woman was also injured in the crash, but the patrol didn't say to what extent​.

The patrol says both were wearing their seat belts.
