York County Coroner Sabrina Gast said in a news release that 55-year-old Ronnie Moore was found on a trail at River Park in Rock Hill around 6:45 p.m. Monday by someone who called 911 and reported he was having seizures.

Gast says Moore died a short time later, and he appears to have been killed by the heat.
