PIEDMONT, S.C. — Greenville County sheriff’s deputies are investigating after a naked man with blood on him told them about a woman’s body. Sheriff’s spokesman Jonathan Smith said in a statement that deputies were called to a road in Piedmont shortly after 6 p.m. Sunday where there had been reports of a naked man with a knife. Smith said the man was acting irrationally and had sustained what appeared to be a self-inflicted chest wound.
