[DOCUMENTED] Socorro NM police officer; sole close-range witness of the Apr 24 1964 landing. A veteran officer regarded as highly reliable; corroborated by Sgt. Chavez (arriving to find him shaken + physical traces), the police chief, and the local FBI agent. Hynek called his credibility 'beyond question.'.
Zamora's reputation for reliability is central to why Blue Book and Hynek treated the case as a genuine unknown rather than a hoax. He drew the craft and its red insignia (oval with landing legs, an inverted-V-with-bars mark) for investigators; the sketch is an exhibit in the Blue Book file.
