ロズウェル事件
Regarding the 1947 Roswell incident, at least three witnesses, including two involved with Army and Air Force counterintelligence, claimed that LaPaz was brought in after the Roswell UFO incident to interview witnesses and reconstruct the trajectory of the crash object. However, UFO researcher Karl T. Pflock discovered some facts that might call into question some aspects of this testimony. For example, one of the purported witnesses to LaPaz's Roswell involvement claimed that LaPaz spoke fluent Spanish, but by interviewing family members, Pflock discovered that LaPaz did not speak any Spanish.
