Peoria Investigation Moves Forward After Arrest in Deadly Collision Involving Isis Horn

 A tragic early morning crash in Peoria, Illinois, has left a community grieving and searching for answers after 17-year-old Isis Horn lost her life in a collision allegedly connected to a fleeing driver. The case has now taken another turn as Shamarr A. Greenlee faces an arrest in connection with the deadly incident, while investigators continue working to uncover details.

According to the Peoria Police Department, Greenlee, 36, was arrested Friday, July 24, in St. Louis, Missouri, by the Woodson Terrace Police Department after authorities obtained an arrest warrant through the Peoria County State’s Attorney’s Office. The warrant charges him with leaving the scene of an accident resulting in death following the crash that claimed Horn’s life. Police said Greenlee is being held at the St. Louis County Jail while awaiting extradition back to Peoria to face the pending charge today.

The investigation began around 1:18 a.m. Thursday, July 23, when a Peoria officer attempted a traffic stop near the intersection of Abington Street and Monroe Street. According to investigators, the vehicle's driver, later identified as Greenlee, failed to stop and fled from police at a high rate of speed. Roughly one minute later, officers discovered a two-vehicle crash involving the same vehicle that had reportedly fled. The crash scene was secured as officers began collecting evidence to understand what happened.

Following the collision, authorities said emergency crews responded and found multiple people affected by the crash. A passenger in the suspect vehicle was injured, taken into custody at the scene, and transported to a local hospital for treatment. Police allege Greenlee left the crash area on foot, beginning a search that continued until his arrest in Missouri the next day. Investigators also worked to identify the circumstances surrounding the collision and locate information that could explain the moments before impact.

The second vehicle involved in the collision was occupied by an 18-year-old male driver and his passenger, Isis Horn, according to authorities. The driver suffered injuries and was transported to a nearby hospital for medical care. Horn, a 17-year-old Peoria resident, sustained fatal injuries and was later pronounced dead by the Peoria County Coroner’s Office, leaving family and friends mourning her sudden loss. His passing has brought sorrow to those closest to him as they continue grieving and seeking comfort.

Authorities continue investigating the circumstances surrounding the crash as officials work to determine the complete sequence of events. The Illinois State Police is handling the collision investigation, while additional legal proceedings against Greenlee are expected after his return to Illinois. Officials have not yet announced whether more charges could be filed as investigators review evidence and gather information. The investigation remains ongoing as detectives examine available evidence and continue reviewing details connected to the events that led to the crash.

The death of Isis Horn has deeply affected those who knew her and members of the Peoria community who are mourning a young life taken far too soon. As the investigation moves forward, loved ones are left remembering the person she was and the memories she created. The case also highlights the lasting consequences that can follow when a driver allegedly flees after a serious crash. Community members continue offering support as the investigation develops and more information becomes available.

Greenlee’s arrest marks a significant development in the investigation, but authorities say the case remains active. As the legal process continues, thoughts remain with Isis Horn’s family, friends, and everyone affected by the tragedy. Her memory will continue to be honored while investigators seek answers and accountability. Community continues to remember Isis Horn and support those grieving her loss.
