A white Dodge pickup was seen early Tuesday morning by Teton County Sheriff Tony Liford as it was driving erratically near Main Street in Driggs, Idaho. Believing the driver may have been driving under the influence based on the driving pattern, Sheriff Liford attempted to stop the vehicle. Instead, the vehicle continued south bound on Main St. in Driggs before leaving the roadway and performing a u-turn, heading north bound back through Driggs. The chase continued on Idaho Highway 33 at high speeds with the operator driving recklessly. Additional Sheriff’s Office deputies joined in the pursuit and continued following the vehicle into Madison County Idaho. Then at approximately mile marker 111 on Highway 33, the vehicle lost control and left the roadway entering a field and rolled. An air ambulance unit was dispatched to the scene and air lifted the sole occupant, a 38 year-old female resident of Driggs, to EIRMC. It was discovered that the driver had sustained a self-inflicted laceration to her throat. The driver’s pet dog was discovered in the vehicle and that it was deceased from a knife wound to its throat. Sheriff Liford says the name of the driver is not being released at this time.
