CASPER, Wyo. – One person is dead and one injured after a rollover on I-90 near Buffalo on Wednesday afternoon.
According to the Wyoming Highway Patrol, a Toyota Tacoma was pulling a Rockwood 1890s Mini Lite camper.

She applied the brakes while encountering dips in the roadway, causing the trailer to sway side to side.
The passenger was sleeping and was woken up. The passenger tried to help hold the steering steady as the driver applied more braking force.
According to the report, the driver then lost control of the combination and it jackknifed to the passenger side, leaving the right side of the roadway where it tipped and rolled.
The camper and truck separated, and the truck continued rolling an underdetermined number of times down a very steep embankment to the bottom of a deep ravine.
During the roll, the passenger side compartment was pushed down, causing the passenger to suffer fatal injuries to the head and neck.
Both occupants were wearing safety belts, according to the report, which lists the deceased as Steven Marshall, 70, from Washington state.
