Sumter Police said fishermen heard Fredric Richburg yelling around 8 p.m. Sunday in a swamp south of the city that is about 5 miles from his apartment.
Authorities say Richburg may have been in the swamp since shortly before he was last seen walking out of his apartment Monday morning. He was reported missing by a friend on Thursday.
Police say in a news release that Richburg is being treated for injuries that aren't life threatening.?
