The St. Johns County Sheriff's Office is investigating a young man's apparent drowning in a golf course pond.
SJSO has identified the man as 19-year-old Tristan William Wingo Peralta of St. Johns County.
Witnesses saw Peralta arrive in a car at the Royal St. Augustine Golf and Country Club on Wednesday night. He then got out and started swimming in the pond, SJSO said.
Peralta started talking to people who were near the pond while he was swimming. Those people told deputies what the man was saying seemed "unusual" and "odd."
At that point, SJSO said, Peralta went under the water and didn't resurface. He was taken to the hospital, where he later died.
Authorities will be looking into the man's medical history and background.
