FRESNO, Calif. (KFSN) --UPDATE: The Fresno County Sheriff's Office says the death is now an ongoing homicide investigation.
Fresno County Sheriff's deputies are investigating a suspicious death Saturday just south of Mendota.
Investigators were alerted to a body alongside the bank of the river across from Jack's Resort near Whitesbridge Avenue. Deputies say the body had been there a few days before being discovered by a fisherman.
Because the area is closed off, deputies are hopeful they can pull tire tracks from a dirt road to get a suspect vehicle.
The identity of the victim has yet to be released.
