Mystery Deepens After Autopsy Fails to Determine Cause of Death in Case of Missing Personal Trainer

The death of 39-year-old Elena Katherine Moore is raising further questions after an autopsy reportedly failed to determine a clear cause of death.

Her body was discovered in a wooded area near Lexington, South Carolina, following a disappearance that began on June 11 after she was last seen at a Planet Fitness location. Authorities initially launched a missing persons investigation before the discovery shifted the case into a death investigation.

According to newly reported details, the autopsy did not immediately establish how she died, prompting additional forensic testing. Investigators are continuing to analyze evidence in an effort to reconstruct the timeline leading up to her disappearance.

Friends of the victim have also begun speaking publicly about the period before she went missing. One close friend, Sondra Campbell, described noticing changes in her behavior in the weeks leading up to the incident, although she also said Elena generally appeared to be managing her life and work.

Originally from Russia, Elena Katherine Moore had built a life in South Carolina, where she worked as a fitness coach and personal trainer. She was married to Brannon Slice, a licensed private investigator and former police officer.

Authorities have stated that her husband, Brannon Slice, is not currently considered a person of interest, and the investigation remains open as officials await further forensic results.

With no definitive cause of death yet confirmed, investigators are reviewing digital records, interviews, and environmental evidence from the area where she was found. The case continues to develop as authorities work to determine what happened in the days after her disappearance.
