POLK COUNTY, Iowa — Authorities have identified the woman who was killed Thursday morning in a tragic collision involving a dump truck and a bicyclist along Northwest 44th Street. The Polk County Sheriff’s Office confirmed that the victim was 44-year-old Courtney R. Petersen of Ankeny, whose sudden death has left her community mourning.
According to officials, the incident occurred around 10 a.m. near the 12100 block of Northwest 44th Street, close to the High Trestle Trail — a route frequently used by cyclists. Deputies responded to reports of a crash between a recumbent-style bicycle and a Des Moines Asphalt and Paving dump truck. When first responders arrived, they found Petersen critically injured. Despite efforts by emergency medical personnel, she was pronounced dead at the scene.
Investigators believe Petersen had been riding on the High Trestle Trail and was attempting to cross Northwest 44th Street when the collision occurred. The dump truck was traveling along the road when it struck her bicycle as she entered the intersection. Authorities have not yet determined whether road conditions, visibility, or traffic played a role. The driver of the dump truck remained on scene and is fully cooperating with law enforcement.
The Polk County Sheriff’s Office said the investigation is ongoing, with crash reconstruction experts working to establish the sequence of events. Detectives are reviewing physical evidence from the scene and any available surveillance footage that could shed light on what happened. Officials have not announced any citations or charges at this stage, emphasizing that their priority is to ensure a complete and accurate review before making further determinations.
Local residents described the area as a busy stretch that sees both heavy vehicle traffic and regular cycling activity, particularly during morning hours. Community members have voiced concerns about safety at trail intersections like Northwest 44th Street, urging greater visibility measures and caution from all road users. Friends and neighbors remembered Petersen as an active and kindhearted individual who loved outdoor activities and often rode her bike through the area.
Authorities extended condolences to Petersen’s family and friends, noting the deep impact of such tragedies on both the community and first responders. The sheriff’s office encouraged anyone who may have witnessed the collision or has relevant information to contact investigators. The case remains under active investigation, with updates expected as more details become available.
