Danker said a city maintenance employee witnessed the theft and followed Dunn northbound on Railroad Highway as the employee notified authorities. Pottawattamie County deputies located Dunn on a county road in Harrison County and attempted to pull the truck over. Danker said the pursuit began when Dunn failed to stop.

The chase covered a number of gravel roads in Pottawattamie, Shelby and Harrison Counties, with deputies from those counties engaging in the pursuit. Speeds during the chase approached 90-mph.  Dunn was able to avoid stop sticks on the highway and eventually traveled to westbound Interstate 680. Deputies deployed stop sticks again on the interstate, blowing out the front tires on the truck, but Dunn managed to keep driving. A short while later a third stop stick attempt blew out the back tires, but again Dunn continued driving.

He eventually turned around in a median, traveling eastbound on I-680, before he was slowed behind semi trucks and eventually pulled over into the median. Authorities arrested Dunn on suspicion of second-degree theft and eluding. Additional charges are possible. Sheriff Danker said after the pursuit Dunn was suffering from stomach pains not related to the chase and was hospitalized. He was scheduled to be transferred to the Pottawattamie County Jail after treatment.
