Antwain Ellis, 27, was released Monday afternoon from University of Mississippi Medical Center, Jackson Police Department spokesman Sgt. Jeffery Scott said.
Ellis was found Sunday afternoon by his mother, who went to his house to check on him.
Scott said Monday the circumstances around the shooting "are not clear," and Jackson police have not yet conducted a formal interview because the elder Ellis was undergoing medical treatment.
There are no suspects and no arrests have been made.
