Ben Carson Campaign Volunteer Dies in Van Crash A staff member and three campaign volunteers for Carson were in a car accident.

 -- A volunteer for Ben Carson's campaign died -- and three other workers were injured -- during an accident in Iowa today, leading the Republican candidate to immediately suspend his campaign activities.

According to a statement released by the Carson campaign, a van transporting the three volunteers and a campaign field director, "hit a patch of ice and flipped on its side where it was struck by another vehicle" around 11 a.m. local time near Atlantic.

Carson suspended all campaign activity for the rest of the day in South Carolina and flew to Omaha, Nebraska, where one of the volunteers, identified by the hospital as Braden Joplin, had been taken for treatment.

He died several hours later, the hospital and campaign said in a joint statement.
