A reported near-collision between two drivers allegedly turned violent after they reached a shopping-center parking lot. The pending Idaho case underscores how quickly a roadside confrontation can become a criminal matter.

A woman was attacked in a Hobby Lobby parking lot in Ammon, Idaho, after a dispute that allegedly involved anger over her not using a turn signal, according to police accounts summarized in court records. Investigators say the alleged attacker, Idaho Falls resident Jaydena Elaine Simpson, smashed the woman’s head into a car during the confrontation.

The alleged July 6 assault has resulted in two felony charges against Simpson, 30. The case offers a stark account of how a traffic disagreement can continue well beyond the road, though the accusations have not been proven in court.

A driving dispute reaches the parking lot

Authorities said the conflict began before either woman arrived at the Hobby Lobby and Kneaders shopping area near 25th East in Ammon.

According to the victim’s account to deputies, Simpson allegedly braked sharply while the victim was trying to pass. Court documents reportedly describe a disagreement over a near-collision, with Simpson accusing the other driver of failing to signal, cutting her off and nearly causing a crash.

Those competing moments on the road are important because they frame the later encounter as an alleged road-rage escalation rather than a dispute that began inside a store. Still, the available reports do not establish every detail of the driving incident independently.

What is clear from the account attributed to law enforcement is that both vehicles then entered the same shopping area, where the disagreement allegedly continued.

Witnesses reported yelling and a struggle

Deputies were called at about 7 p.m. after witnesses reported yelling and saw two women involved in a physical altercation in the parking lot, according to the reports.

A witness told investigators that Simpson allegedly went to the rear of her vehicle and retrieved a tire iron. Court records, as summarized in published coverage, say she swung the object and made threats toward the other woman.

It is not clear from the available source material whether the tire iron made contact with anyone. The reported allegation involving the woman’s injuries centers instead on a physical confrontation near a vehicle.

The victim reportedly tried to get another person’s attention and attempted to return to her vehicle. According to her statement to deputies, Simpson then approached her, grabbed her and repeatedly struck her head against the vehicle.

Police documented facial injuries

When deputies arrived, the woman had a bloodied face and injuries to her hands, according to court records cited in the reports. She was taken for medical evaluation.

A CT scan later showed fractures involving her nose and septum in three places, the published account said. Those reported medical findings are why the incident is being treated as more than a fleeting parking-lot confrontation.

The source material does not identify the injured woman, and this article is not naming her. It also does not provide a complete account of any medical treatment beyond the evaluation and scan described in the court-record summary.

Witnesses reportedly yelled and honked vehicle horns in an effort to stop the confrontation. The reports say Simpson left shortly afterward.

Two felony counts are pending

Simpson was arrested and faces two felony counts connected to the alleged incident, according to the available reporting. The specific names of the charges were not included in the extracted source material, so they cannot be reliably stated here.

She was reportedly released on her own recognizance while the case moved forward. Earlier coverage said a preliminary hearing was scheduled for Aug. 19, but the material provided does not identify the year or confirm whether that hearing occurred, was continued or produced any later ruling.

Simpson is represented by a public defender, according to the reports. A public defender’s office generally does not comment on pending cases, and no defense account of the incident was included in the available material.

A criminal charge is an accusation, not a finding of guilt. Prosecutors would have to prove the allegations in court, and Simpson is entitled to contest the evidence and allegations.

Why parking-lot conflicts carry risk

Parking lots can create the conditions for a minor driving frustration to become personal. Drivers are moving slowly, looking for spaces, yielding to pedestrians and watching vehicles pull in and out from several directions at once.

That does not excuse violence. But it helps explain why a perceived slight, such as a missed turn signal or a close pass, can remain emotionally charged after drivers park.

The alleged Ammon incident also illustrates a practical safety point: once a confrontation shifts from gestures or shouted words to following someone into a destination, the safest priority is often distance rather than finishing the argument.

These steps cannot guarantee safety, and people caught in sudden confrontations may have little time to react. The responsibility for an alleged assault rests with the person accused of committing it, not with someone involved in an earlier traffic disagreement.

The court process will determine facts

The most serious details in this case come from police accounts, witness statements and court documents summarized by published reports. They describe what investigators say happened, not a final judicial determination.

Questions remain about the full sequence of the road encounter, the evidence prosecutors intend to present and the current procedural status of the case. Those issues will be addressed, if the case proceeds, through the Idaho court process.

For now, the reported incident stands as an allegation of a dispute over a turn signal that escalated into a violent encounter in a Hobby Lobby parking lot. The felony case, rather than the initial roadside accusation, will determine the legal outcome.
