Summary based on the NamUs case record (MP19028) and 7 other sources
Jason William Dies, a 20-year-old petty officer in the U.S. Navy, was last seen in San Diego, California, on June 18, 1991. Having just returned from deployment aboard the USS Horne following Operation Desert Storm, he was on leave and scheduled to report to his new duty station in Pensacola, Florida, by July 18. However, he never arrived, and when he failed to show up, the Navy initially classified him as absent without authorization and later as a deserter. Despite this classification, his family believes Jason intended to fulfill his duty and report for his new assignment.

Before disappearing, Jason mailed packages to his family in Louisiana and instructed them not to open them. These packages were postmarked June 18, the day he was last seen, and were sent from a naval station in Pensacola, suggesting he had intended to visit his family before reporting to Florida. His family followed his instructions and left the packages unopened for nearly a decade. When they were eventually opened, they contained gifts for his family, further deepening the mystery.

Jason’s disappearance remains unsolved, and there have been no significant developments in the case. Investigations by both the Naval Criminal Investigative Service (NCIS) and the FBI have yielded little new information. His family continues to search for answers, believing Jason may have been planning to surprise them with a visit during his leave before something went tragically wrong. Jason’s case is still open, and authorities urge anyone with information to come forward.
