Four people were injured Wednesday afternoon, during a rollover accident in Council Bluffs. Authorities say the accident happened a little after 1:30-p.m., on southbound I-29 near the Avenue G Exit.

When Council Bluffs Fire Department paramedics and law enforcement arrived on the scene, they found a Chevy Trailblazer that had rolled off of the interstate. Four passengers were inside the vehicle at the time of the accident and all were transported to Nebraska Medicine in critical condition. As of the latest report, three of the passengers were still in critical condition, including the driver of the vehicle, Conrado Munoz, who is from Nebraska. The fourth passenger was an infant and is in stable condition.

The Traffic Unit is currently investigating the incident and do not believe alcohol was involved. They are working to determine if speed was a factor in the crash. I-29 southbound was closed for about two hours.
