Medical examiners in Charleston have yet to determine the cause of death or the identity of a man whose body was found floating Wednesday in the ocean off Folly Field Beach.
They did say that an autopsy Thursday determined his death was not the result of foul play.
Pathologists at the Medical University of South Carolina want to see the results of toxicology tests before determining what caused the man's death, Beaufort County Deputy Coroner David Ott said.
Such tests typically take four to six weeks, according to the Coroner's Office.
Ott said the circumstances of the man's death might become more clear once he is identified.
But no one matching the man's description -- a black male in his 30s or 40s wearing only swim trunks and a wristwatch -- has been reported missing recently, and he had no identification on him when two beachgoers behind the Island Club off Folly Field Road pulled him from the water.
The man was pronounced dead at the scene, and authorities say he might have been in the water since Tuesday, possibly longer.
Ott said the Coroner's Office and Sheriff's Office are working with MUSC to confirm the man's identity using his fingerprints and medical information.
Ott said they hoped to know who the man is "in the next day or two."
