South Carolina fitness trainer made cryptic Instagram comments weeks before her body was found

The South Carolina fitness trainer who vanished for nearly a week made mysterious social media comments just three weeks before her body was discovered.

Elena Katherine Moore, 39, was found dead almost a week after she disappeared on June 11 after she went to a Planet Fitness gym in Lexington, South Carolina. The Lexington County Coroner's Office said in a statement on Monday that a forensic autopsy did not find indications of bruising, lacerations, gunshot wounds, stab wounds, blunt force trauma, strangulation or other external injuries.

Her cause of death is pending as investigators wait for additional testing and a review of Moore's medical records.

A spokeswoman for the Lexington Police Department confirmed to Fox News Digital that Moore was also reported missing on June 5, but no action was taken because she was located. Friends of Moore told Fox News Digital she checked herself into a psychiatric facility during that timeframe.

Moore was found dead near Old Cherokee Road and Northlake Drive in Lexington County on June 17. Lexington Police Chief Terrence Green said that her body was located after a tip led them to a new search area.

Sondra Campbell, who was close friends with Moore, told Fox News Digital that something felt "very different" the last time she saw her on May 31.

"She was scared for her life. She actually said those words to me," Campbell said. "Elena is one of my best friends. I've known her over probably 10 years now. We're really close like tell each other everything. She's been that person for me for a long time."

Authorities have not said whether they suspect foul play, and the South Carolina Law Enforcement Division is handling the investigation into Moore's death.
