A volunteer for the Ben Carson campaign died of his injuries after a car crash in Iowa early Tuesday morning.

Carson announced he would temporarily suspend his campaign and travel from South Carolina to Omaha to visit the family of 25-year-old Braden Joplin.

Joplin was involved in the crash with three other campaign volunteers when the van lost control and was hit by another vehicle.

The other passengers were treated and released, but Joplin’s injuries were more severe. He died after 4:30 p.m. local time, a statement from the hospital said.
