A Wyoming resident was killed and a passenger was injured Sunday afternoon near Casper after a rollover crash on Interstate 25.

John Gallatin, 35, was partially ejected from the vehicle during the crash and died at the scene. His passenger, 33-year-old Amanda Gallatin, was totally ejected and was taken to the hospital with serious injuries.

The Wyoming Highway Patrol says in a crash report that the crash occurred shortly after 5 p.m. Sunday near mile maker 184.

Gallatin was driving a Subaru northbound, when a deer ran out into the roadway. Witnesses in other vehicles told troopers that the Subaru swerved to avoid hitting the deer.

Evidence at the scene indicated that Gallatin overcorrected to the right, then again to the left, causing the Subaru to go into a slide in the direction of the passenger side.

The Subaru then ran off the right side of the interstate, went into the soft dirt in the borrow ditch and rolled three to four times.

The crash report shows Gallatin was not wearing his seat belt properly.

Road conditions at the time of the crash were listed as dry, with clear weather.

Gallatin was the 116th person killed on Wyoming highways in 2017. By this point in 2016, 102 fatalities had been reported. In 2015, the number was 133 deaths, with 134 by this point in 2014.
