More information

S/Sgt Ralph Mourer enlisted in Denver, Colorado on 2 February 1943. His son Victor was born after S/Sgt Mourer's death.

The airplane was shot down by enemy fighters. The entire crew of ten was killed.

The crash site could not be located by Allied forces during the war, and the remains of all ten crewmembers, including Mourer, were unaccounted for following the war.
Beginning in 1946, the American Graves Registration Command (AGRC), the organization that searched for and recovered fallen American personnel in the European Theater, began investigating the numerous bomber losses in the Salzwedel and Wistedt areas of Germany. German forces had maintained accurate documentation (Kampfflugzeug Unterlagen, or KU reports) of American aircraft shoot-downs, with several reports indicating B-24s crashing in the area. However, AGRC was unable to associate any KU reports with Little Joe and investigators were unable to locate any crash or burial sites associated with the loss.
In 2015, an independent research group, Missing Allied Air Crew Research Team (MAACRT), contacted DPAA historians with new information related to a possible crash site near Wistedt, Germany. Interviews with elderly local residents indicated there were two crash sites, but only one was recovered by American forces following the war. Investigators located the second crash site and were able to recover various pieces of wreckage. Possible osseous remains were also located and transferred to the DPAA laboratory for analysis and identification. At the time, no matches could be made with any Unknowns and further investigations were scheduled.
Between 2021 and 2023, DPAA investigators returned to the crash site and continued investigations, and then excavations and recoveries. By the end of November 2023, all evidence, including possible osseous remains and possible life support equipment, had been recovered and returned to the DPAA laboratory.
To identify Mourer’s remains, scientists from DPAA used anthropological and dental analysis. Additionally, scientists from the Armed Forces Medical Examiner System used mitochondrial DNA (mtDNA) and Y-chromosome DNA (Y-STR) analysis.

Mourer’s name is recorded on the Walls of the Missing at Netherlands American Cemetery, Margraten, Netherlands, along with others still missing from WWII. A rosette will be placed next to his name to indicate he has been accounted for.

S/Sgt Mourer will be buried in Adrian, Michigan, in the spring of 2025 (information added November 2024).
