UPDATE: 

The Teton County Sheriff's Office has released the following press release:

On 07/09/2019 at approximately 5:22 AM, Teton County Sheriff Tony Liford observed a white Dodge pickup driving erratically near Main St. and Wallace Ave., Driggs, ID. Sheriff Liford believed the driver may have been driving under the influence based on the driving pattern and attempted to stop the vehicle. 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 and continuing on ID Highway 33 at high speeds and driving recklessly.

Additional Sheriff’s Office deputies joined in the pursuit and continued following the vehicle into Madison County Idaho.

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 while investigating the scene that the driver 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.

The Sheriff’s Office would like to thank Madison County Sheriff’s Office, Idaho State Police, Madison Fire Department and Idaho Lifelflight for their assistance in this incident.

Her medical status is still unknown. 

----------

MADISON COUNTY − Two Upper Valley County Sheriff's offices joined in pursuing an individual in a white pick up truck early Tuesday morning. The pursuit resulted in a crashed vehicle and the individual being life flighted to a medical facility.  

Teton County Sheriff's officers started pursuing Lindsey Asselin early Tuesday morning. TCSO later asked the Madison County Sheriff’s Office for help pursuing her. Yet, by the time law enforcement reached Asselin, she crashed her vehicle in a field and needed to be life flighted to a medical facility.

“This morning at approximately 5:39 a.m. the Teton County Sheriff’s Office contacted Madison County Dispatch to request assistance in a pursuit of a vehicle headed into Madison County,” the release from MCSO read. “Madison County Sheriff’s Deputies were dispatched. While deputies were in route, the vehicle crashed at approximately 5:49 a.m. at milepost 111 East of Newdale.”

This crash is now being investigated by the Idaho State Police.

Deputy Isaac Payne, public relations officer for MCSO, said that it is unclear why the TCSO pursued Asselin, but that “pursuits are always a kind of judgment call,” he said. “And the general rule is that they’ll decide to continue a pursuit when there is an imminent threat. So they felt she was a threat and continued to pursue her.”

He said that it was his understanding that Asselin was having trouble maintaining her lane and was driving erratically.

Payne said she crashed in a field. What exactly she hit in the field is unknown, as law enforcement wasn’t there when she crashed but were en route to her.

Payne said Asselin was life flighted to a medical facility, and her status is currently unknown. 

“We don’t life-flight many people around here, so take it as you will,” he said.

The TCSO was unavailable for comment.
