The patrol says a 2004 Western Star tractor-trailer was headed west on Wyoming 220 when the driver lost control due to a strong wind gust, after which the truck left the right side of the road and overturned before sliding down the embankment.

Authorities have identified the driver as 59-year-old Elmwood, Wisconsin resident Lawrence Hughes.

Hughes was taken to Wyoming Medical Center for his injuries.

Hughes' passenger, 59-year-old Machael Hughes, also died from her injuries after being taken to Wyoming Medical Center. She, too, was wearing her seatbelt.

Wednesday's crash marks the ninth fatality on Wyoming's roadways compared to three at this same point in 2020.
