The picture at the bottom shows you how this is on the same property as the police and fire departments. And they found human remains in a vehicle associated with a a missing person case from 22 years ago while doing dive training.

On Thursday, Sept. 25, 2025, just before 11 a.m., divers from the Naperville Fire Department were conducting training exercises in Lake Osborne, located just south of the Naperville Public Safety Campus on Aurora Avenue, when they discovered a submerged vehicle in the southwest portion of the lake.

Naperville Police officers, detectives, and crime scene technicians were called to the scene to assist with the recovery of the vehicle and initiate an investigation. At approximately 3:40 p.m., the vehicle was removed from the lake and identified as a 1992 Nissan Maxima.

Using the vehicle’s older license plate number, investigators determined that the vehicle was connected to an ongoing Berwyn Police Department investigation into the disappearance of Hiep Luu, who was reported missing in 2003. Suspected human remains were located inside the vehicle but have not yet been identified. The DuPage County Coroner’s Office was called to assist with the investigation and will handle identification of the deceased.
