Jaydena Elaine Simpson, 30, of Idaho Falls, was arrested and charged with two felony counts following an alleged violent assault in an Ammon, Idaho, parking lot on July 6. The incident reportedly stemmed from a road rage dispute that escalated into a physical confrontation, leaving the victim with serious facial injuries, including multiple fractures to her nose and septum.
"You would 'f*** your car up and f*** you up." — Jaydena Elaine Simpson (allegedly), Accused
According to court documents reviewed by East Idaho News, deputies responded around 7 p.m. to a report of an assault in the Hobby Lobby and Kneaders parking lot near 25th East. Witnesses at the scene reported hearing yelling and observing two women involved in a physical altercation. Authorities detailed that the confrontation followed an earlier dispute between the two drivers, which began on the road involving a near-collision before they entered the shopping center's parking area.
The victim provided a statement to deputies, alleging that Simpson had abruptly slammed on her brakes as the victim attempted to pass, initiating the disagreement between the two. Conversely, court documents indicate that Simpson accused the victim of failing to use a turn signal, cutting her off, and nearly causing a crash. Both accounts suggest a rapid escalation of tension during the traffic encounter.
The disagreement reportedly continued as both vehicles entered the shopping area, where the situation took a disturbing turn. A witness informed investigators that Simpson allegedly retrieved a tire iron from the back of her vehicle after parking. Court documents further state that Simpson allegedly swung the tire iron and threatened the other woman, telling her she would "f*** your car up and f*** you up." This verbal threat reportedly preceded the physical assault.
The victim attempted to seek attention from another person nearby and tried to return to her vehicle, presumably to de-escalate the situation or escape. However, according to the victim's statement, Simpson then approached her as she was attempting to leave, allegedly grabbing her before repeatedly striking her head against the vehicle. Witnesses present reportedly intervened by yelling at Simpson and honking their horns in an effort to stop the violent confrontation.
Shortly after the alleged attack, court documents indicate that Simpson left the scene. When deputies arrived, they found the victim with visible injuries, including a bloodied face and hands. The woman was subsequently taken for medical evaluation. A CT scan conducted during her evaluation revealed significant injuries, specifically fractures to her nose and septum in three separate places, underscoring the severity of the alleged assault.
Simpson was arrested and subsequently charged with two felony counts related to the alleged incident. Following her arrest, she was released on her own recognizance, pending further court proceedings. Her preliminary hearing is scheduled for August 19, according to court records obtained by Law & Crime. Simpson is being represented by a public defender, and the Idaho State Public Defender’s Office maintains a policy of not commenting on pending cases.
This case highlights the potential for everyday disagreements, such as those arising from road rage, to escalate into serious criminal matters with severe consequences for all involved. The alleged incident serves as a stark reminder of the dangers of aggressive driving and the importance of conflict resolution in public spaces. The legal process will now proceed, with prosecutors working to present their case and determine if the allegations against Simpson can be proven in court. The outcome of the preliminary hearing will be a critical step in determining the future trajectory of this case.
