Idaho State Police Investigate Collision Involving Lewiston Patrol Vehicle; Public Asked to Come Forward
Early Morning Crash at Lewiston Intersection Leaves Two Hospitalized
Idaho State Police are actively investigating a traffic collision involving a Lewiston Police Department patrol vehicle that occurred in the early morning hours at a downtown Lewiston intersection. The crash prompted a multi-agency response and left the intersection closed for approximately six hours.
According to an ISP news release, the collision occurred at approximately 1:15 a.m. Sunday at the intersection of D Street and 5th Street in Lewiston, Idaho. A Lewiston Police Department patrol vehicle — a black 2018 Chevrolet Tahoe — was traveling westbound on D Street when the driver of a black 2009 Cadillac Escalade struck the patrol vehicle on the driver’s side while attempting to pass.
The patrol vehicle was driven by a 30-year-old female officer from Lewiston. Idaho State Police identified the driver of the Cadillac Escalade as 29-year-old Tristyn Weeks of Lewiston. Both drivers sustained minor injuries and were transported to a local hospital for treatment, according to ISP.
The intersection of D Street and 5th Street was closed for approximately six hours as emergency responders worked the scene and investigators gathered evidence. The extended closure allowed law enforcement and public works personnel to conduct a thorough examination of the crash site.
Multi-Agency Response Supports Active Investigation
The Idaho State Police were assisted at the scene by several agencies, reflecting the coordinated response that has become standard practice for serious traffic incidents in Nez Perce County. Assisting agencies included the Lewiston Police Department, the Nez Perce County Sheriff’s Office, the Lewiston Prosecutor’s Office, Lewiston Fire Department, and Lewiston Public Works.
ISP has not released details regarding the specific circumstances that led to the collision, including whether speed, impairment, or other factors may have played a role. As the investigation remains active, authorities are asking the public to assist by coming forward with any relevant information.
Anyone who had contact with Tristyn Weeks prior to the crash, or who observed the black 2009 Cadillac Escalade before the collision, is urged to contact Idaho State Police at (208) 750-9300 and reference case number 2026-00051803.
Public cooperation in traffic investigations is often critical to establishing an accurate timeline of events, particularly when crashes occur in the overnight hours with limited witnesses. ISP’s request for information suggests investigators believe additional witnesses or individuals with relevant knowledge may not yet have come forward.
Lewiston Officer Collision Raises Public Safety Awareness
The incident highlights the ongoing hazards faced by law enforcement officers during routine patrol operations in the Lewis-Clark Valley. Officers on overnight patrol face a particular set of risks, including reduced visibility and the potential for encountering impaired or reckless drivers during late-night hours.
Lewiston, situated in the heart of Nez Perce County along the Snake and Clearwater rivers, relies on its police department to maintain order across a community that includes active commercial corridors and residential neighborhoods. Collisions involving patrol vehicles, while not uncommon nationally, are serious incidents that trigger independent investigation to ensure transparency and accountability.
The Lewiston Police Department has been involved in several notable public safety incidents in recent months. In a separate matter, a Lewiston woman was charged after allegedly spraying a bus driver, passenger, and officer with a chemical substance, underscoring the range of challenges local law enforcement regularly confronts.
Public safety in Nez Perce County also extends beyond law enforcement incidents. Earlier this year, a mountain lion was euthanized near Lewiston after an urban sighting raised concerns about resident safety — a reminder that Idaho’s communities sit at the edge of diverse and sometimes unpredictable terrain.
What Comes Next
Idaho State Police continue to lead the investigation into the D Street collision. No charges or citations have been publicly announced as of this report, and the investigation remains open. Investigators are encouraging anyone with information about the movements of the black 2009 Cadillac Escalade or its driver prior to the crash to contact ISP at (208) 750-9300 with reference to case number 2026-00051803. Further developments are expected as the investigation progresses and findings are reviewed. Nez Perce County News will continue to follow this story as additional information becomes available.
