The Marine Corps has identified a student at Marine Corps University in Quantico, Virginia, who died earlier this month as Sgt. Jaen Deshun Davis, Corps officials announced.

Davis, 24, was found unresponsive in his vehicle on Sept. 2 and pronounced dead at the scene, a Marine Corps news release says.

No information was immediately available about the cause of Davis’s death. The Naval Criminal Investigative Service is looking into the matter.

Davis was participating in enlisted professional military education at Marine Corps University at the time of his death. He was assigned to reserve unit 1st Battalion, 24th Marine Regiment in Selfridge, Michigan, where he served on the active-duty Inspector Inspector-Instruction Staff, the news release says.
