David Paulides is a former police officer who is now an investigator and writer known primarily for his books dedicated to proving the reality of Bigfoot, and establishing the Missing 411 conspiracy theory. Missing 411 is a series of self-published books and films, which document cases of people who have gone missing in national parks and elsewhere, and assert that these cases are unusual and mysterious, contrary to data analysis which suggests that they are not actually statistically mysterious or even unexpected.^[1][2]

Paulides has Greek ancestry.^[3] In his online biography page, Paulides states that he received his undergraduate and graduate degrees from the University of San Francisco, and in 1977 he began a 20-year career in law enforcement, transferring in 1980 to the San Jose Police Department, working in the patrol division on the SWAT Team, patrol, and Street Crimes Unit, and a variety of assignments in the detective division.^[4] While working as a court liaison officer in December 1996, Paulides was charged with a misdemeanor count of falsely soliciting for a charity.^[5]

After leaving the police force, Paulides wrote books on the topic of Bigfoot, as well as on the disappearances of people in national parks and elsewhere which he attributes to unspecified, unknown causes.

In his pursuit of Bigfoot, Paulides has published two Bigfoot-related books and founded the group North America Bigfoot Search,^[6][7] for which he serves as director.^[8]

Paulides has said North America Bigfoot Search was instrumental in the genesis of a paper published in 2013, which claimed that Bigfoot was real: "The world needs to understand that North America Bigfoot Search was the organizer of the study. We orchestrated the search that led to picking Melba S. Ketchum to conduct a study of bigfoot DNA."^[9] The resulting paper documented the analysis of 111 samples of hypothesized Bigfoot DNA and was written by 11 different authors.^[8] On November 24, 2012, DNA Diagnostics, a veterinary laboratory headed by Ketchum, issued a press release prior to peer review claiming that their DNA sequencing study confirmed the existence of a hominin hybrid cross between modern humans with an unknown primate.^[8] Two months later, in the inaugural issue of DeNovo: Journal of Science,^[8] the paper was analyzed by Sharon Hill of Doubtful News for the Committee for Skeptical Inquiry. Hill's report concluded that the paper was of poor quality, stating that "The few experienced geneticists who viewed the paper reported a dismal opinion of it, noting it made little sense."^[8]

The Scientist magazine also analyzed the paper, reporting that the analyses and data fail to support the claims of existence of a human-primate hybrid, but rather, "analyses either come back as 100 percent human, or fail in ways that suggest technical artifacts."^[10] The website for the DeNovo Journal of Science was set up on February 4, and there is no indication that Ketchum's work, the only study it has published, was peer reviewed.^[10]

Following his work on Bigfoot, Paulides' next project was Missing 411, a series of self-published books and two documentary films, documenting unsolved cases of people who have gone missing in national parks and elsewhere.

According to Paulides, his work on this subject began when he was doing research in a national park and an (unnamed) off-duty park ranger approached him and expressed concern about the questionable nature of some of the missing person cases which occurred in the parks.^{[11][page needed]} The ranger knew Paulides' background and asked him to research the issue.^[12][7] Paulides obliged, and asserts that he uncovered multiple lines of evidence suggesting negligence on the part of the park service in failing to locate the missing people.^[13] He broadened his investigation to include missing people from across the world, and this led to his belief that he has uncovered a mysterious series of worldwide disappearances, which he said defied logical and conventional explanations.^{[14][page needed][15][unreliable source?]}

As of August 2021,^[update] Paulides has written at least ten books on this topic. According to A Sobering Coincidence, he does not yet have a theory on what is causing the disappearances, although he indicates that the "field of suspects is narrowing." Paulides advised his readers to go outside of their normal comfort zone to determine who (or what) is the culprit.^{[16][17][failed verification]}

Paulides' books publicized the fact that the US National Park Service does not keep an independent list of people that go missing in their parks.^[7] While there is a database for incident and criminal reports, it is not widely or consistently used and it doesn't interface with other criminal databases.^[7] In response, a petition was created to make the department accountable.^[18]

The interest in the book series prompted the creation of a documentary film based on the Missing 411 books; this film was released in 2017.^{[citation needed]} Images of maps made by Paulides regarding his theory have been frequently shared on social media.^[19] The theory has also gone viral on TikTok.^[20]

Kyle Polich, a data scientist and host of the Data Skeptic podcast, documented his analysis of Paulides' claims in the article "Missing411"^[21] and presented his analysis to a SkeptiCamp held in 2017 by the Monterey County Skeptics.^[22][1] He concluded that the allegedly unusual disappearances represent nothing unusual at all, and are instead best explained by non-mysterious causes such as falling or sudden health crises leading to a lone person becoming immobilized off-trail, drowning,^[23] bear (or other animal) attack, environmental exposure, or even deliberate disappearance. After analyzing the missing person data, Polich concluded that these cases are not "outside the frequency that one would expect, or that there is anything unexplainable that I was able to identify."^[24] This presentation was discussed in a February 2017 article in Skeptical Inquirer, a publication of the CSI. In the article, Susan Gerbic reported "Paulides ... gave no reason for these disappearances but finds odd correlations for them. For example, two women missing in different years both had names starting with an 'A' with three-letters, Amy and Ann."^[1] Polich concluded in his analysis: "I've exhausted my exploration for anything genuinely unusual. After careful review, to me, not a single case stands out nor do the frequencies involved seem outside of expectations."^[2]
