Postwar Search
Postwar, Quinn's records were compared with laboratory data for all unidentified remains recovered from that area with negative results. On August 22, 1951 a team from American Graves Registration Service (AGRS) searched for Quinn, Hartman and Jones in the map coordinate indicated and interviewed native Okinawan people but their search had negative results. The next day, the team recommended all three MIA cases be declared non-recoverable. Inside the caves they explored they located skeletal remains that were all deemed to be Japanese based on their equipment and other means of identification. Officially on November 21, 1951 he was one of three Americans declared non-recoverable by a board review by Col. C. H. Elmes, Quartermaster Corps.

Dog Tag Discovery
During 1993, a dog tag for John B. Quinn, Jr. was located "outside a cave" and was later presented to Marine 2nd Lt. Kerry J. Quinn by his Sergeant Major while they were stationed on Okinawa as the Lieutenant had the same surname. Later, he attempted to locate the family and return the dog tag to them. In 2011, while searching the 6th Marine Division Association website he located one of Quinn's relatives, Larry Paleno and contacted him and mailed him the dog tag. On 2012, the dog tag of John B. Quinn, Jr. was returned to his family. On May 18, 2012 the two Quinn families met at the National World War II Memorial in Washington DC.

Contemporary Searches
During 2018, Japanese NGO Kuentai-USA performed two independent searches for Quinn at the map coordinates indicated in his Individual Deceased Personnel File (IDPF). During these searches, they located Japanese remains, artifacts and unexploded ordnance, but no trace of Quinn.

On March 30, 2019, Kuentai-USA with Pacific Wrecks again searched for Quinn in southern Okinawa. During this visit they located more Japanese remains, artifacts and unexploded ordnance, but no trace of Quinn.
