Police say a passerby made the discovery behind Christian Temple just before 11 a.m. Sunday morning. The church is located near Cedar and Belmont.
Investigators are calling the finding suspicious. At this time the man has not been identified.
Action News talked to church-goers soon after the finding.
"I am sad and I'm real angry that someone would come out here, especially behind our church, and do this," church-goer Manuel Orozco said.
At this time investigators are working to find the cause of the man's death.
