A third Marine Corps investigation into the identities of the six second flag-raisers concluded in October 2019, that Pfc. Harold Keller was in the Rosenthal's photograph in place of Pfc. Rene Gagnon (fifth from left). Gagnon who carried the larger second flag up Mount Suribachi, helped lower the first flagstaff and removed the first flag to take down to the Second Battalion command post. The identities of the other five flag raisers were confirmed. The changes were the mainly result of focusing on Pfc. Keller and Pfc. Gagnon and comparison of even more photographs than the previous investigation. Like Schultz, Keller did not ever say publicly he was a flag-raiser or that he was in the photograph.
