The body of 19-year-old Humberto Nunez of Reedley was found near an orchard at Polk and Whitesbridge.
Investigators believe the body was left at that location by someone else.
Detectives are trying to figure out what Nunez was doing Saturday night before he was killed.
Anyone with information is asked to contact the Fresno County Sheriff's Department.
An autopsy will be performed later this week to determine the cause of death.
