HONOLULU — The Navy said Tuesday its investigation into a shooting at Pearl Harbor last December was unable to determine what caused a submarine sailor to fire his service weapon at three civilian workers, killing two and wounding one, before he fatally shot himself.
But the Navy’s investigative report said 22-year-old Gabriel Romero had “several stressors” in his life in the months leading up to the shooting that together “likely led him to choose violence.”
Further, the report said the U.S. Pacific Fleet submarine force’s mental health program failed to properly diagnose Romero’s mental health condition during eight visits he made to a clinic between September and November 2019.
Still, U.S. Pacific Fleet Commander Adm. John Aquilino said no one could have predicted Romero would “engage in this ultimate act of murder and suicide” even if his mental health issues and his grievances had been known.
“This lack of predictability on mass shooting incidences, despite information that often does emerge after the fact as ‘warning signs’ has confounded experts across the globe,” Aquilino said in a memo forwarding the report to the vice chief of naval operations.
Romero was assigned to the USS Columbia submarine, which was in dry dock at the Pearl Harbor Naval Shipyard at the time of the Dec. 4 shooting. His job was to stand watch and provide security for the submarine.
He used his service-issued M-4 rifle to shoot the civilians and a service-issued M-9 rifle to shoot himself immediately afterward. The shooting — which killed Roldan Agustin, 49, and Vincent Kapoi Jr., 30, and wounded Roger Nakamine, 36 — lasted a few seconds.
Romero completed annual arms screening in September 2019.
