The remains were found about 9:30 p.m. Sunday, but the Sheriff’s Department did not release information about the discovery until Monday afternoon.
“No additional information will be released at this time regarding this incident due to the active investigation and until next of kin is notified,” sheriff’s spokeswoman Kelly Hoover said in a written statement.
The Criminal Investigations Division is looking into the death as suspicious, but authorities did not say why they labeled it that way.
Forensics Unit personnel spent Monday processing the scene, Hoover said, who added that Search and Rescue Team members also looked for evidence in the riverbed.
The name of the victim won’t be released until family members are notified, Hoover said.
Additional information, including the woman’s age or other circumstances surrounding the discovery and investigation, was not released.
