Nearly four months after the body of a missing South Carolina fitness enthusiast was found, authorities have determined that 39-year-old Elena Katherine Moore died of natural causes stemming from a heart condition, ending months of speculation surrounding her disappearance.
Lexington County Coroner Margaret Fisher announced Friday that Moore died from complications of cardiac dysrhythmia with premature ventricular contractions, a condition involving an abnormal heart rhythm.
Fisher said the autopsy found no evidence of traumatic injuries, including broken bones, strangulation or sexual assault. Toxicology testing detected alcohol but no other substances.

“We never saw anything that would indicate homicide. Nothing,” Fisher said. “We were able to follow her path. We were able to pull her medical history, her mental history. We knew that this was not a homicide.”

The coroner also addressed speculation surrounding Moore’s husband, Brannon Slice, saying he was never considered a suspect or person of interest in the investigation.

Fisher went further, crediting Slice with repeatedly trying to get his wife help as she struggled with a serious mental health crisis in the days before her disappearance.
“The only person that really tried to help this girl to get her help through the system is her husband,” Fisher said. “He reached out. He tried many times to get her help.”
