The following is confirmation from https://grok.com/ that Paul Bennewitz and Gabe Valdez were legitimate researchers into claims of the Dulce Base and Cattle Mutilations, and that many of their claims can be substamtiated:

GROK COMMENTARY:
After reviewing the provided document and conducting thorough searches across a diverse range of sources (including web searches for corroborations from conspiracy communities, UFO forums, historical records, and related publications), I focused exclusively on human-sourced claims related to the Dulce Base and its alleged activities. Per your instructions, I applied strict logical parameters: corroboration requires multiple independent human sources (e.g., witnesses, researchers, or investigators) confirming the same specific details without reliance on circular references (where one source merely echoes another without new evidence). I ignored all scientific opinions, theories, suppositions, skeptical viewpoints, and unsubstantiated assertions. Emergent perspectives were considered only where patterns of overlapping confirmations from distinct individuals appeared.

Only claims that meet this corroboration threshold are included below. The vast majority of claims in the document (e.g., underground wars, reptilian control, specific abductions, or base structures) do not qualify, as they stem from single testimonies, anonymous sources, or interdependent conspiracy narratives without independent human confirmation. Where corroboration exists, it is limited to basic historical details about individuals' involvement or reports, not the fantastical elements. Detailed commentaries are provided for each qualifying source/witness.

Paul Bennewitz:
Bennewitz, a physicist and electronics company owner, claimed to have observed UFO activity near Dulce, New Mexico, in the late 1970s, including signals he interpreted as communications from an underground alien base under Archuleta Mesa. He also linked this to cattle mutilations in the area.

Corroborated Elements: Multiple independent human sources confirm Bennewitz's personal observations and reports of UFO sightings and signals near Dulce. Gabe Valdez (a New Mexico State Police officer who investigated cattle mutilations) corroborated Bennewitz's involvement by sharing details of joint fieldwork, including visits to sites where Bennewitz pointed out alleged base entrances or vents. Richard Doty (a former AFOSI agent) confirmed in interviews and books (e.g., his own statements in "Exempt from Disclosure") that Bennewitz reported these sightings and provided photographic evidence to authorities. William Moore (a UFO researcher and co-author of "The Philadelphia Experiment") independently confirmed Bennewitz's claims in his writings, noting Bennewitz's submission of films and data to APRO (Aerial Phenomena Research Organization). Norio Hayakawa (a UFO investigator) corroborated the historical timeline of Bennewitz's reports through on-site investigations and interviews with locals in Dulce since the 1980s, confirming Bennewitz's role in originating the base rumors. Commentary: These corroborations form an emergent pattern of Bennewitz as the initial human source for Dulce-related UFO claims, with independent confirmations from law enforcement (Valdez), military intelligence (Doty), and researchers (Moore, Hayakawa). However, they align only on Bennewitz's reported observations and communications, not on the existence of an operational base or alien activities. Logically, this establishes Bennewitz as a foundational witness but does not extend to broader claims like underground facilities or abductions.

Gabe Valdez:
Valdez, a New Mexico State Police officer, investigated cattle mutilations and UFO sightings in the Dulce area during the 1970s and 1980s. The document mentions his collaboration with Bennewitz on site visits and photography of an alleged sealed entrance to the base.

Corroborated Elements: Independent human sources confirm Valdez's investigations into cattle mutilations and UFO reports near Dulce. Paul Bennewitz corroborated Valdez's involvement by describing joint expeditions to photograph potential base entrances in his own accounts and letters. Greg Valdez (Gabe's son and author of "Dulce Base: The Truth and Evidence from the Case Files of Gabe Valdez") confirmed his father's case files, including FBI collaborations on mutilations and site visits with Bennewitz. Norio Hayakawa independently corroborated Valdez's fieldwork through interviews with locals and review of police reports, noting Valdez's documentation of unusual lights and animal deaths in the Archuleta Mesa area. FBI records (declassified via FOIA) confirm Valdez as a key investigator, with memos referencing his reports on mutilations from 1975–1980. Commentary: An emergent perspective here is Valdez as a law enforcement bridge to civilian claims, with corroborations from family (Greg Valdez), collaborators (Bennewitz), researchers (Hayakawa), and official records (FBI). This logically supports Valdez's role in documenting phenomena in the area, but only regarding surface-level investigations like mutilations and lights, not underground base activities or alien encounters.
