The Department of Defense POW/Missing Personnel Office (DPMO) announced today
that the remains of a U.S. serviceman, missing in action from World War II, have been identified
and are being returned to his family for burial with full military honors.
Army Air Forces 2nd Lt. Regis E. Dietz, 28, of Pittsburgh, will be buried on April 8 in
Bridgeville, Penn. Dietz, along with 11 other crew members, took off on Oct. 27, 1943, in their
B-24D Liberator from an airfield near Port Moresby, New Guinea. Allied plans were being
formulated to mount an attack on the Japanese redoubt at Rabaul, New Britain. American
strategists considered it critical to take Rabaul in order to support the eventual invasion of the
Philippines. The crew’s assigned area of reconnaissance was the nearby shipping lanes in the
Bismarck Sea. But during their mission, they were radioed to land at a friendly air strip nearby
due to poor weather conditions. The last radio transmission from the crew did not indicate their
location. Multiple search missions in the following weeks did not locate the aircraft.
Following World War II, the Army Graves Registration Service conducted searches for 43
missing airmen, including Dietz, in the area but concluded in June 1949 that all were
In August 2003 a team from the Joint POW/MIA Accounting Command (JPAC) received
information on a crash site from a citizen in Papua New Guinea while they were investigating
another case. He also turned over an identification card from one of the crew members and
reported that there were possible human remains at the site of the crash. Twice in 2004 other
JPAC teams attempted to visit the site but were unable to do so due to poor weather and
hazardous conditions at the helicopter landing site. Another team was able to successfully
excavate the site from January to March 2007 where they found several identification tags from
the B-24D crew as well as human remains.
Among other forensic identification tools and circumstantial evidence, scientists from JPAC
and the Armed Forces DNA Identification Laboratory used mitochondrial DNA—which matched that
of Dietz’s nephew—in the identification of his remains.
Of the 16 million Americans who served in World War II, more than 400,000 died. At the
end of the war, the U.S. government was unable to recover and identify approximately 79,000
Americans. Today, more than 74,000 are unaccounted-for from the conflict.
