Farrar, 42, was last seen Sunday morning. A missing persons report had been filed Wednesday. Police were told at that time Farrar had ingested a large number of pills following a domestic argument.
No obvious signs of foul play were seen, police said today.
The body has been taken to Nashville, where a autopsy was to be conducted today, and the Tennessee Bureau of Investigation has taken over the case.
Farrar was found by relatives in a wooded tree line between St. Williams Catholic Church and a soccer park behind Shelbyville Power, Water and Sewerage System.
Police were told he had grown up in the area where he was found.
Longtime residents of Shelbyville may remember a white block building near the intersection which once stood near the South Brittain Street-South Main Street intersection.
Police said Farrar had once lived in the area around that building, which had been just a few feet from the area where he was found.
A cousin of Farrar's and another man were looking for him near the church when they discovered the body and flagged down a passing police car.
Officer David Dye said Farrar was lying "just inside the woods."
"The body had possibly been in the woods for some time," Dye said in his report.
