USS California – Pearl Harbor Unknowns


At the Department of Defense, Rick Stone served as the Deputy Chief of the World War II Research and Investigation Branch and was the primary investigator assigned to the cases of American sailors listed as “Unresolved” from the USS California during the attack on Pearl Harbor, December 7, 1941.  Chief Stone developed an extensive computer database to develop multiple statistical and historical datasets on unidentified casualties from the USS California. At the time of Chief Stone’s investigations, twenty men from the USS California remained in an “Unresolved” status in the Joint POW/MIA Accounting Command (JPAC) database, including three officers. Twenty-three bodies, or portions of bodies, identified after the attack as being from the USS California were previously buried as an “Unknown” in the National Memorial Cemetery of the Pacific (Punchbowl) in Honolulu, Hawaii.  

Chief Stone utilized comparison biometric profiling and statistical correlations as investigative research techniques in completing official Investigative Reports on all 23 burials of USS California “Unknowns” in the Punchbowl. Research resulted in lists of names being developed for the three standard investigative categories in each of the 23 cases investigated:

1) Possible Matches……………………2) Probable Matches…………………..3) Most Likely Matches

Each list was progressively refined by investigation until the smallest number of matches was obtained. The average number in the smallest refined category developed in each case was four . Three Punchbowl burials were determined to be smaller portions of one of the other twenty “Unknowns” recovered with larger amounts of remains present. In these three cases disinterment was not recommended. Disinterment and a full forensic review was recommended by Chief Stone in 20 of the 23 Punchbowl cases investigated on 21 February 2012 . The investigation in 17 of these cases resulted in the smallest refined number of matches being five or less, including four cases which were refined to only a single match to the specific unknown casualty.

When asked on their intent for pursuing the identification of unknowns from the USS California, a senior JPAC Laboratory Manager reported the laboratory would not attempt to identify ANY remains which were found in the water and could not be securely placed as recovered from the USS California, including any remains recovered on December 7, 1941 and recorded in the Bureau of Naval Medicine documents as USS California casualties. As a result of this stance, not a single USS California “Unknown” from the Punchbowl was ever the subject of a JPAC forensic examination.

Fortunately, JPAC was disbanded in 2015 and it’s replacement agency, the Defense POW/MIA Accounting Agency (DPAA), gained access to all of Chief Stone’s Investigative Reports.  Six years after Chief Stone’s recommendations for recovery and identification of these heroes, exhumations of the USS California “Unknowns” began in February 2018.

On 12 October 2021, the first USS California “Unknown” was finally identified:
