A drill instructor assigned to Marine Corps Recruit Depot Parris Island was found dead in her apartment on July 17, the service confirmed.
Sgt. Darilyn C. Duong, a DI with the 3rd Recruit Training Battalion, was found in her apartment in Port Royal, just north of the installation. She was 25 years old.
The cause of death is currently under investigation, Marine spokesperson 2nd Lt. Joshua Hartley said in a statement.
“The Marine Corps extends its deepest condolences to the family, friends and fellow Marines affected by this loss,” Hartley said. “At this time, it would be premature to speculate on the circumstances or results of the investigation. … Out of respect for the Marine’s family and loved ones, no additional details will be released at this time.”
A native of Winnebago, Nebraska, Duong is the second drill instructor assigned to Parris Island to be found dead in as many months.
On May 30, Sgt. Albert Haynes II, 24, was found dead in a hotel room in Starke, Florida, where he was staying while attending a poolee function with U.S. Marine Corps Recruiting Station-Jacksonville.
Duong, who was single with no dependents, enlisted in the Marine Corps as a Food Service Specialist before becoming a drill instructor.
Her awards include the Global War on Terrorism Service Medal, the Navy Meritorious Unit Commendation, two Sea Service Deployment Ribbons, two Good Conduct Medals and the National Defense Service Medal.
