Two Utah men killed in separate Wyoming rollover crashes

CASPER, Wyo. — Two Utah residents died in separate rollover crashes on Wyoming highways in recent days, according to crash reports from the Wyoming Highway Patrol.

On March 15, a 29-year-old Utah man died in a crash in Sweetwater County near Rock Springs.

At about 1:53 a.m., a Chevrolet Trailblazer traveling on U.S. Highway 191 South failed to negotiate a right-hand curve near milepost 547. The driver, identified as JC Slaugh, drifted off the right side of the road before overcorrecting to the left. The SUV then spun counterclockwise, left the roadway to the left and struck a guardrail. The vehicle rolled several times down a steep cliff, traveling roughly 150 feet before coming to rest on its roof.

Slaugh was wearing a seat belt at the time of the crash, the WHP report states. The road was dry and the weather was clear. The exact time of the crash is still under investigation by the WHP.

Earlier in the week, a 69-year-old truck driver from Utah died in a rollover crash in Fremont County near Lander.

On March 12 at 5:45 p.m., Michael Sandrone was driving a Peterbilt semitrailer east on Wyoming Highway 28. While negotiating a left downhill curve near milepost 59.3, the truck drifted out of its lane and exited the right side of the road, tipping onto its passenger side. The vehicle continued down an embankment and into a ditch, it ultimately rolled upside down.

Sandrone was wearing a seat belt, the report states. The WHP reported severe wind conditions at the time of the incident and listed speed as a possible contributing factor in the crash.
