Recovery of Remains
On August 19, 1946 a RAAF Searcher Team led by Ft Lt Belcher visited the crash site and exhumed the grave and transported the remains to Ambon. Afterwards, they were identified as American and turned over to American Graves Registration Service (AGRS) and later identified as pilot Dean and transported to Hawaii for permanent burial.

Page 16: "[August 19, 1946] Next we went to the site of the crashed plane below the battery, this was a crashed American Douglas A20, the plane was identified as such by the star on the wing and the number plates (enclosed). A grave about 20 meters from the wreckage was marked with a cross inscribed 'Unknown soldier died July 1944'. This grave and the remains of one body only was recovered, th dental state was good and if the dental charts of the crew of this A-20 can be obtained from the American Personnel Research Section, identity may be established. A thorough search was made of the ground near the wreckage but no other grave was located."
