Today, we honor the South Carolina deputy who made the ultimate sacrifice during dive training.
Every public safety diver understands that the risks are real. We train relentlessly, not because it’s easy, but because someone else’s worst day may depend on our readiness.
Our thoughts and prayers are with the deputy’s family, friends, fellow deputies, and the entire public safety diving community during this difficult time.
May we honor this sacrifice by continuing to train with purpose, serve with courage, and always look out for one another.
Rest easy, We’ll take it from here. We have the watch.
A Lexington County Sheriff’s Department deputy died Thursday during an underwater training session with the agency’s dive team on Lake Murray.
Jillian Olson, 29, began her career as a Lexington County deputy in 2021.
After more than a year as a patrol deputy, she transferred to a warrant deputy position.
Olson was promoted to master deputy in the Warrant Division in 2025. She had been a member of the Lexington County Sheriff’s Department dive team since 2024.
“Our hearts are broken by the loss of a valuable member of the Sheriff’s Department,” Lexington County Sheriff Jay Koon said.
