One of the four Ben Carson campaign workers injured in a car accident in western Iowa on Tuesday has died, the Des Moines Register’s Jennifer Jacobs reported on Twitter. The male volunteer, Braden Joplin, was 25.

According to the Associated Press, Carson cancelled his scheduled events after the Tuesday morning crash: the van carrying three volunteers and a paid staffer hit an icy patch in the road in Cass County, Iowa, flipped onto its side, and was struck by another vehicle.

Carson was in South Carolina on Tuesday, but had made plans to fly to Omaha to meet with the workers in the crash.

Update – 9:24 pm
