LEXINGTON — A 29-year-old deputy with the Lexington County Sheriff’s Department died July 30 during an underwater training session on Lake Murray.
The sheriff’s department said Jillian Olson had been a member of the dive team since 2024.
The coroner’s office is investigating the cause of Olson’s death.
The S.C.
Department of Natural Resources led recovery efforts, with assistance from the State Law Enforcement Division.
The agencies are continuing to investigate.
DNR said they will conduct an evaluation of the technical dive components of the investigation and test the dive equipment with the proper entities and outside expert opinion.
“Law enforcement divers willingly accept extraordinary risks in service to others, training tirelessly to prepare for emergencies most people never see,” DNR said in a press release.
“Their commitment extends fat beyond the call of duty, and their sacrifice is one shared by the entire first responder community.”
Who was Jillian Olson?
Olson, who earned a master’s degree from Western Illinois University, started her career with the department as a patrol deputy in 2021.
She was promoted to master deputy in the warrant division in 2025.
She was scheduled to receive the department’s five-year honorable service award next month.
“Jillian’s dedication to her community and department is well-documented with awards and recognitions,” Sheriff Jay Koon said.
“She’ll be most remembered for what she did with no fanfare.
Her decision to join our dive team is just one example of her going above and beyond.”
