A farm worker made the discovery around 6:30 a.m. in a field off of Manning and Hill Avenues near Orange Cove.
Investigators won't say if the victim was murdered in the orchard where he was found or whether he was dumped there.
Chris Curtice with the Fresno County Sheriff's Office said, "The body is that of a male and he was burned. The detectives aren't releasing any other details about the body. We're still trying to figure out who it is."
Deputies are working to first identify the victim before they begin re-tracing his steps. He did not have any identification on him when he died.
