Mr S is the man who found Hae's body in Leakin Park.
His story is that he was driving back to his job from lunch, he stopped by the side of the road, then walked into the woods in Leakin Park to urinate. He walked 127 feet into the woods, and claimed he noticed Hae's body buried behind a log.
Questions / Controversy
The forensic examiner testified that the body would have been hard to spot, and even when standing near the body, he didn't notice it. This raises questions about whether Mr S had previous knowledge of the location of the body.
SK tells listeners that she kept Mr. S's identity a secret because of his history of run-ins with the police due to his streaking.
