HONOLULU (KHON2) — Officials responded to an active shooter at the Pearl Harbor Naval Shipyard, at Dry Dock 2 at around 2:30 on Wednesday, Dec. 4.

Within just minutes of the incident, the base was placed on lockdown.

“Working in the office. Military personnel came in and said there’s an active shooter and told us to stay inside, gonna lock up the base,” said a Pearl Harbor base worker. “Basically, no one can get in or out and they’ll let us know when clear. The building personnel was running around trying to lock all the doors.”

In a press conference held Wednesday evening, Rear Admiral Robert Chadwick said that the shooter had been identified as an active-duty U.S. Sailor assigned to the USS Columbia.

Admiral Chadwick also said that the shooter reportedly shot and injured three Department of Defense civilian workers before killing himself. Two of the three victims later died. The third victim, a 36-year-old man, is in stable condition at Queen’s Medical Center.

Sources have identified one of the victims as 32-year-old Vincent Kapoi Jr. of Waianae.

It is unclear if the victims were targeted.

Officials said that the base security and the Navy Criminal Investigative Service (NCIS) are investigating. The names of the victims will not be released until the next of kin has been notified.

Due to the security incident, access and gates to JBPHH were closed. The lockdown was later lifted and all gates were reopened around 4 p.m.

The public was advised to avoid heavy traffic on Kamehameha and Nimitz Highway.
