Crash on Interstate 90 Near Mitchell Claims Two Lives
According to the South Dakota Department of Public Safety, the crash involved a 2018 Dodge Ram traveling eastbound between the Mitchell exits along Interstate 90.
For reasons still under investigation, the vehicle left the roadway, entered the south ditch, and struck a guard cable near a bridge over Rowley Street.
The impact caused the truck to fall onto Rowley Street below, where it subsequently collided with a retaining wall.
The driver of the vehicle was identified as 34-year-old Shane Tyler Willis of Pierre.
A passenger, 38-year-old Melynda Jean Willis, also of Pierre, was in the vehicle at the time of the crash. Both individuals sustained fatal injuries.
Officials confirmed that all occupants of the vehicle were wearing seat belts at the time of the incident.
Two infant passengers were also in the truck. Authorities reported that the children suffered minor injuries and were transported for medical care.
No further details regarding their current condition have been released.
Preliminary findings from investigators suggest the sequence of events began when the pickup drifted off the roadway for unknown reasons.
The vehicle then struck infrastructure near the bridge approach before dropping onto the lower roadway surface.
The South Dakota Highway Patrol continues to examine what factors may have contributed to the crash, including road conditions, driver input, and mechanical issues.
Investigation Continues, and Community Prepares Vigil
Law enforcement officials have stated that the investigation remains active, and additional details may be released as findings are confirmed.
