Nevada City – On July 21, 2025, the Nevada County Sheriff’s Office (NCSO) launched a death investigation after an unidentified individual was found deceased on the side of Banner Quaker Hill Rd. in Nevada City. Due to the level of decomposition, a positive identification of the individual was not immediately available, nor a cause of death.

Since that time, NCSO detectives have been working on this case and through the course of the investigation, the decedent was identified as Adrian Aaron Aaby, 48, of Grass Valley. Aaby’s family was notified of his passing.

On July 29, an initial examination of the body was performed at Placer County Morgue to determine the cause of death, but autopsy results are presently pending final review by the pathologist. It may take several weeks before NCSO receives the results.

In the meantime, this case remains under active investigation. Anyone with information on the death of Aaby is asked to call the NCSO’s Major Crimes Unit at (530) 265-1471.
