What Changed

On Thursday, July 30, 2026, a 29-year-old member of the Lexington County Sheriff's Department dive team died during an underwater training session on Lake Murray in South Carolina. She joined the agency in 2021, had served on the dive team since 2024 and had been recognized with several awards, including the agency's Outstanding Judicial Services Deputy of the Year in 2023.

Sheriff Jay Koon said her "dedication to her community and department is well-documented with awards and recognitions."

The South Carolina Department of Natural Resources is leading the investigation with help from the South Carolina Law Enforcement Division. The Lexington County Coroner's Office is investigating the cause of death, which had not been released at the time of reporting.

What It Says

The public record says very little so far, and it is important to be clear about that.

  • We do not know the cause of death.
  • We do not know what happened during the training session.
  • We do not know what safety or medical measures were in place.
  • Nothing in the public record points to any failure by the agency, the dive team or anyone else.

This article is not about assigning blame. It is about a question every agency should be able to answer before the next high-risk training day.

Why It Matters Operationally

Specialty teams train in environments that can injure or kill on their own: water, heat, heights, live fire, confined spaces, vehicles and force-on-force. That risk is part of why the training is valuable. Realistic training exposes problems before the real call does.

But realism has a price, and leadership owns it. When an agency schedules a high-risk evolution, it is also deciding what happens if someone goes down during it. Who is trained to respond? What equipment is on site? How far away is EMS, and how do they get to the patient? Has anyone practiced the emergency plan, or does it exist only on paper?

Military clinical guidance treats these hazards as specific medical problems with specific responses. The Joint Trauma System maintains a Drowning Management CPG (ID64) and hosts guidance on the Prevention, Diagnosis and Management of Exertional Heat Illness. A general first-aid plan is not the same thing as a plan built for the hazard in front of you.

ODM's Position

Position: Every high-risk training evolution should have a written, rehearsed medical plan matched to the specific hazard, with trained personnel and equipment on site. That is a leadership and budget decision, not something instructors should have to improvise.

Evidence: Specialty training puts responders in environments with known medical hazards, and the military's own clinical guidelines address drowning and exertional heat illness as distinct problems with distinct responses. This death, whatever its cause turns out to be, is a reminder that serious emergencies during training are not hypothetical.

Strongest counterpoint: Dive teams and other specialty units often already follow detailed safety standards and dive protocols, and accidents can happen even when everything is done right. Adding layers of safety process can also push agencies toward sanitized training that does not build real capability. Both points are fair. The answer is not less realistic training. It is realistic training with a medical plan that is as serious as the training itself.

What good looks like:

  • A designated safety officer with authority to stop training.
  • Medical personnel on site trained for the specific hazard, whether that is water, heat or live fire, with the right equipment staged.
  • A written emergency action plan covering communications, EMS access, transport destination and who makes the call.
  • A drill of that emergency plan at the start of the training cycle.
  • An after-action review for every serious training injury, with lessons shared across the agency.

What Your Agency Should Do Now

  • Inventory every high-risk training evolution your agency runs and confirm each has a written medical plan.
  • Check that on-site medical coverage is trained for the specific hazard, not just general first aid.
  • Confirm EMS access routes and transport times for remote training sites, including water and range locations.
  • Rehearse the emergency action plan, not just the training scenario.
  • Budget for training safety and medical coverage as a recurring line item.

Bottom Line

A deputy who had earned her place on a specialty team died during training, and her agency and community are grieving. The cause is still under investigation, and we will not speculate. The question for every other agency is simple: if someone goes down at your next training day, is the medical plan as real as the training?
