JUST IN: She Was “OVERDOSED”? Elena Moore Toxicology Report Just Exposed A Shocking Death Update?

Inside the Elena Moore Investigation: A Detective’s Firsthand Account By Detective Brian Colwel, Lexington County Sheriff’s Office / SLED Task Force

I’ve been in law enforcement for over eighteen years, and I’ve worked missing persons cases that turned into death investigations more times than I care to count. But Elena Katherine Moore’s case stays with me. It’s the kind that doesn’t let go easily—because what we found on the surface didn’t match the life she was living, and the gaps in her final hours raised more questions than answers.

I was directly involved in the timeline reconstruction and evidence coordination after her body was recovered on June 17, 2026. What follows is my detailed account based on the official record, interviews I helped conduct or reviewed, surveillance we pulled, and the forensic work still unfolding at MUSC. This is not tabloid speculation. It’s the view from inside the investigation as we wait for toxicology and histology results.

The Day Everything Changed: June 11, 2026

Elena was released from Three Rivers Behavioral Health in West Columbia on the morning of June 11. I’ve sat across from enough people who’ve just left treatment facilities to know that day can feel like both relief and disorientation. According to the detailed timeline we built with Crime Timelines data and witness statements, she was out before 2:00 p.m. The facility arranged a cab for her.

That cab stopped at the CVS on 5608 Sunset Boulevard in Lexington at Elena’s request. The driver waited, then went inside looking for her when she didn’t return. She was already gone. That decision—to deliberately separate from her ride—has been one of the most scrutinized moments in this case, and for good reason. In my experience, people don’t slip away from safe transport unless they have somewhere specific they need to be that they don’t want others to know about.

From that CVS to her check-in at Planet Fitness on Whiteford Way at 6:38 p.m., we have a multi-hour gap with no public footage accounting for her movements. Those hours matter. A woman recently discharged from mental health treatment, alone on foot in the South Carolina afternoon heat—what did she do? Did she meet someone? Did she need time to think? We’ve asked those questions repeatedly.

At Planet Fitness, Elena didn’t work out. She signed in using her regular membership and took a shower. I’ve reviewed the gym footage and spoken with staff who knew her face. This wasn’t a workout session. It looked like someone seeking normalcy and basic comfort after days in a facility. For a personal trainer who valued routine and physical self-care, that shower may have been her way of reclaiming a piece of herself before whatever came next.

She left the gym, walked through the commercial area near Lowe’s (where her car remained parked—she never got in it), and appeared on public surveillance at 9:17 p.m. wearing an olive green zip-up hoodie and black athletic pants, heading toward Old Cherokee Road. After that frame, the cameras go dark. That image is burned into my mind: a woman walking alone into the growing darkness.

The Medical Thread: Her Heart Condition

One of the most important details I’ve focused on is Elena’s pre-existing heart condition, which her longtime friend Sandre Campbell publicly confirmed. Elena had taken a job at CVS in part to secure health insurance because of emerging cardiac issues. As a 39-year-old personal trainer at Wolf’s Fitness Center, she wasn’t living a sedentary life. She pushed clients through demanding workouts daily. In my years investigating deaths, I’ve learned that cardiac vulnerabilities in otherwise fit people can hide in plain sight—episodes of dizziness, palpitations, or sudden confusion that get dismissed as stress or anxiety.

This becomes critical when you look at the Ring doorbell footage from around June 4. Neighbors Sarah Berles and John Moore described Elena appearing genuinely disoriented—picking up the wrong DoorDash order, trying to follow someone inside, later rummaging through packages and admitting she didn’t know why she was there. Police also documented similar behavior near a Kohl’s. She was panting, breathing heavily.

Campbell was adamant that this was not the Elena she or Elena’s clients knew. Even during intense training, Elena was sharp and capable. I’ve reviewed that footage myself. A cardiac arrhythmia causing temporary reduction in cerebral blood flow can produce exactly that kind of acute, reversible disorientation. The person snaps back but feels lost about the lost time.

At autopsy on June 20, Coroner Margaret Fiser found no external trauma—no bruising, lacerations, gunshot or stab wounds, no signs of strangulation or blunt force. The exterior told us very little. That’s why the three parallel tracks at MUSC are so important: comprehensive toxicology (including vitreous fluid, which holds up better in heat), histological examination of tissues looking for cellular damage like contraction band necrosis, and full medical records review.

If stress-induced Takotsubo cardiomyopathy or a related event occurred, it would show specific microscopic changes in the heart muscle. Women are far more susceptible. Chronic stress—especially the grinding kind that comes from feeling trapped—elevates cortisol and keeps the sympathetic nervous system in overdrive. In a heart that already has vulnerabilities, that can be the final trigger. No dramatic external event needed. Just the body reaching its limit.

The Relationship Dynamics and Elena’s Private World

Elena had been with Brandon Slice since approximately 2013. They married on February 29, 2024. Friends described a long pattern of Elena wanting to leave, cycles of trying to exit, then staying. A 2017 message showed her already contemplating ending things and looking for a roommate. She worked three jobs—trainer, pharmacy tech, bartender. That level of hustle often signals financial pressure or a need for independence.

Campbell told interviewers that Elena had expressed being “scared for my life” at their May 31 brunch. She was looking out windows, uneasy. This was distinct from her usual anxiety, according to Campbell. Elena loved life and looked forward to her days. Yet privately, on a second Instagram account, she wrote about pain, betrayal, exhaustion, and being in a relationship with the devil while searching for a way out.

I’ve seen this pattern in other cases: the public performance of stability while privately unraveling. Elena maintained two versions of herself—one for clients and the world, one raw and honest on her private page. That emotional labor is its own chronic stressor. The gap between who she presented as a trainer helping others get stronger and what she was carrying at home takes a heavy physiological toll.

Slice reported her missing. Before the search gained national attention, he posted publicly that his wife “was not well” and later deleted it. He also apologized for sharing an older photo. These actions were noted by the public and by us. Slice has not been named a suspect or person of interest. He cooperated, and investigators working with his family described him as genuinely distraught. Private investigator Henry Dukes disputed some of Campbell’s characterizations, and Campbell pushed back directly.

As detectives, we don’t take sides in public narratives. We build the factual record. The texture of the relationship—documented over years by friends—is part of understanding the stress Elena lived with. People in long-term entrapment dynamics don’t leave cleanly. They love and resent simultaneously. They stay longer than outsiders understand.

The Forensic Process Unfolding Now

I’ve coordinated with the coroner’s office and MUSC pathologists. The standard toxicology panel covers a broad range, but a negative doesn’t rule out everything—especially after six days in June heat. Vitreous fluid gives us the best shot at reliable data. Histology is looking for organ-specific damage patterns that bloodwork might miss: inflammation, cell death, necrosis.

Medical records will calibrate everything. What exactly was her documented cardiac history? Any prior episodes misattributed to anxiety? Medications? Recent visits?

Results typically take 6-10 weeks. We expect them between early August and early September 2026. Whatever comes back—cardiac event, toxic exposure, environmental, or undetermined—will shape the next phase. An undetermined ruling doesn’t close the case. SLED took over as a full death investigation precisely because manner and cause were unknown. We continue building the record: surveillance, witness statements, timelines, relationships.

What the Community Still Holds

The tip that located Elena came from a resident who saw her entering the wooded area near Lakeside Middle School on the evening of June 11. That single call on June 16 led searchers to her at 2:48 p.m. the next day. One call made the difference.

There may still be people who saw something in the commercial strip, the parking lot, or the woods that evening. If you were in the area of Planet Fitness, Public’s, Old Cherokee Road, or Lakeside Middle School on June 11, please reach out. SLED tip line: 803-737-9000. Email: [email protected].

Elena’s clients at Wolf’s spoke of a dedicated trainer who showed up for them. The gym provided full cooperation. Her friends described a woman who was trying to speak her truth in those final weeks—afraid, pulling away, but still performing normalcy.

My Take as the Detective Who Worked the Case

In my career, I’ve learned that deaths like this rarely have one simple explanation. Mental health treatment, cardiac vulnerability, relational stress, and the unaccounted hours all intersect. The body keeps the score. Chronic fear and the effort of maintaining two realities can push a compromised heart past its limits.

Elena walked into those woods in the clothes she’d worn after leaving the treatment facility. She was found in the same hoodie. Whatever happened between 9:17 p.m. and the time her body came to rest, the laboratory in Charleston is now reading the cellular story.

I’ve sat with the surveillance stills. I’ve read the private posts. I’ve listened to friends who loved her. This case isn’t just about determining cause of death. It’s about understanding the conditions that led a woman who loved life to walk alone into the dark.

The science will give us a foundation. SLED will follow every lead from there. Elena Moore deserves a complete accounting—not headlines, but rigorous truth.

If new information comes in, we’ll pursue it. Until then, we wait on the labs while continuing the work quietly and methodically—the way serious investigations are done.

To the people who knew Elena: thank you for speaking with us. To anyone with information: come forward. One call already helped us find her. The next might help us understand how she got there.

Elena was trying to find her way out of fear and pain. I hope the full record we’re building honors that struggle.
