The register

Every record, in one table.

Sorted by record number. Filter by status or by category. Records marked entry in preparation are indexed but not yet written; the register lists them so that the scope of the archive is visible rather than implied.

Privacy Policy

This policy explains what information Anomaly Registry collects when you visit this website, why it is collected, how it is used, and what choices you have. It applies to anomalyregistry.com and to any subdomain operated by us. It was last updated on the date shown at the end of this policy, and we will revise it if our practices change.

We have designed this site to collect as little personal information as possible. You do not need an account to read anything here. There is no login, no user profile, no newsletter list, and no comment system. In the ordinary course of reading the register, you are not asked to identify yourself, and we do not ask you to.

Like virtually every web server, ours produces access logs. These logs record the internet protocol address of the requesting device, the date and time of the request, the page or file requested, the referring page if one was sent, and the browser user agent string. These logs exist for security, abuse prevention, and diagnosing technical faults. They are retained for a limited period and then discarded. We do not use them to build profiles of individual readers.

If you write to us through the contact form, we receive whatever you choose to put into it: typically a name, an email address, and a message. We use that information for the sole purpose of reading and answering your message. We do not add correspondents to a mailing list, and we do not sell, rent, or trade contact details with anyone.

Corrections are a special case, and worth stating plainly. If you write to point out an error in a record, we may act on that correction and revise the entry. We will not publish your name or your email address in connection with a correction unless you explicitly ask us to be credited.

This site is supported by advertising served through Google Ad Manager. Advertising technology providers may set and read cookies or similar identifiers on your device in order to select advertisements, limit how often you see the same advertisement, and measure performance. These identifiers are set by those third parties, not by us, and the data they collect is governed by their own privacy policies rather than this one.

We do not have access to the personal data that advertising partners collect, and we cannot delete it on your behalf. If you wish to limit interest-based advertising, you can adjust the advertising settings offered by Google, use your browser's cookie controls, or use the industry opt-out tools that are available in your region. Details are set out in our Cookie Policy.

We may use privacy-respecting aggregate analytics to understand which records are being read and how people move through the register. Where we do, we configure it to avoid collecting information that identifies individual readers. Aggregate figures tell us that a case page is popular; they do not tell us who read it.

We do not knowingly collect personal information from children. This site is a documentary archive intended for a general adult and older student readership. If you believe a child has sent us personal information through the contact form, write to us and we will delete it.

Depending on where you live, you may have rights over personal data relating to you, including the right to ask what we hold, to ask for a copy, to ask for correction, and to ask for deletion. Because we hold so little, these requests are usually simple to answer. Write to us and we will respond within the period required by the law that applies to you.

Our servers are located in North America, and information sent to this site is processed there. If you are visiting from elsewhere, your request necessarily crosses borders in order to reach us. By using the site you understand that this transfer takes place.

If we change this policy, the revised version will be posted here with a new date. Material changes will be noted plainly rather than buried. Questions about this policy should be sent through the contact page.

Cookie Policy

A cookie is a small text file that a website asks your browser to store, and that your browser sends back on later requests. Similar technologies, including local storage and pixel tags, do comparable work. This policy explains which of these are used on Anomaly Registry, by whom, and what you can do about them.

The registry itself is a reading site. It does not require a cookie to show you a record. We do not set cookies to track you across the internet, and we do not operate a first-party advertising identifier of our own.

Strictly necessary cookies may be set to keep the site secure and functioning, for example to help mitigate automated abuse of the contact form. These are limited in scope and are not used for advertising or profiling.

Advertising cookies are set by Google Ad Manager and by the advertising technology partners that operate within it. Their purposes include selecting which advertisement to show, capping the number of times a given advertisement is repeated, detecting invalid traffic and click fraud, and measuring whether an advertisement was actually seen.

Some of these advertising cookies support interest-based advertising, in which the advertisement you see is influenced by inferences drawn from browsing activity over time and across sites. Whether this occurs depends on your region, your settings, and the choices you have already made with those providers.

We may use aggregate analytics to count page views and understand which records are read. Where an analytics tool is used, we prefer configurations that do not identify individual readers and that do not follow readers across other websites.

We do not embed social media widgets, share buttons, or tracking pixels from social networks. This is a deliberate choice for an archive of this kind, and it removes an entire category of third-party tracking that most content sites carry.

Your browser gives you direct control over cookies. Every major browser can block third-party cookies, delete existing cookies, and clear stored data on exit. Blocking third-party cookies will not prevent you from reading anything on this site, though it may make the advertising you see less relevant.

You can also manage advertising preferences with Google directly through its advertising settings, and through the industry opt-out mechanisms operated in various regions. Because these are operated by third parties, we cannot make the choice on your behalf.

Where the law in your region requires consent before non-essential cookies are set, a consent notice will be shown and your choice will be respected. Withdrawing consent later is possible through the same mechanism.

Advertising partners may change over time. Rather than publish a list that goes stale, we identify the advertising system in use, which is Google Ad Manager, and direct you to Google's own disclosures for the current set of partners operating within it.

If you have a question about cookies on this site that this policy does not answer, write to us through the contact page and we will answer it.

Anomaly Registry is an independent documentary archive. It is published as a work of reference and public interest reporting, and it is supported by advertising. It is not affiliated with, endorsed by, or acting on behalf of any government, university, police service, coroner, scientific institution, or investigative body named in any record.

The register documents real events, including in some cases deaths, criminal investigations, and inquests. Where a record concerns a criminal matter, nothing on this site should be read as an allegation of guilt against any living person. Where an individual has been named in the public record, we report the fact of that naming and its evidentiary standing; we do not accuse.

Records are written from sources. Where a source is a primary document, we say so. Where a claim rests on secondary reporting, we say so. Where sources conflict, we state the conflict rather than quietly choosing a side. Where a widely repeated claim cannot be traced to any source, we say that too, because an untraceable claim is itself a finding.

Every record separates what is documented from what has been proposed. Hypotheses are labelled as hypotheses and attributed to whoever advanced them, together with their standing: peer-reviewed, contested, dismissed, or untested. We do not advance theories of our own.

The registry treats its own entries as provisional. Records carry a review date, and they are revised when the evidence changes. A record you read today may be corrected tomorrow, and that is a feature of the method rather than a defect in it.

Despite this method, errors will occur. If you find one, write to us. Corrections supported by evidence are made promptly, and we would rather be corrected than be consistent.

Scientific and forensic conclusions reported here are the conclusions of the researchers and officials who reached them, not ours. Reporting that a study proposed a mechanism is not an endorsement that the mechanism is correct, and the status assigned to a case reflects the state of the evidence rather than our opinion of it.

Nothing on this site is legal, medical, psychological, financial, or safety advice. Records that touch on medical or psychological matters, including mass psychogenic illness, report the diagnoses reached by clinicians at the time and afterward. They are not a substitute for professional care.

Quotations from sources are used sparingly and for the purposes of reporting, comment, criticism, and review. Copyright in quoted material remains with its owner. If you hold rights in material you believe has been used improperly, contact us and we will address it.

Original text, structure, record numbering, and editorial apparatus on this site are the property of Anomaly Registry. You are welcome to quote briefly and link to us. Wholesale reproduction of records, including reproduction for the purpose of training generative models, is not permitted without written permission.

Outbound links are provided as references. We do not control linked sites and are not responsible for their content, their accuracy, or their handling of your data.

This site is operated from British Columbia, Canada, and these notices are governed by the laws applicable there, without regard to conflict-of-law principles.

Accessibility Statement

Anomaly Registry is built to be usable by as many people as possible, including people who use screen readers, keyboard navigation, magnification, or other assistive technology. We treat accessibility as part of the build rather than as a later remediation.

We aim to meet the Web Content Accessibility Guidelines version 2.1 at level AA. This is a target we work toward continuously rather than a certification we claim to have completed.

The site is written as semantic HTML. Headings describe the real structure of a record, lists are marked up as lists, and the register is a genuine table with proper header cells, so that a screen reader can announce which column a value belongs to.

Every interactive element is reachable and operable by keyboard alone. Focus is visible at all times, and a skip link at the top of each page lets keyboard and screen reader users jump straight to the register without traversing the navigation.

Status is never conveyed by colour alone. Each status carries its written label in text, so a reader who does not perceive the colour difference between "Unsolved" and "Debunked" still receives the distinction.

Text colours have been chosen to meet or exceed the contrast ratios required at level AA against the page background. The typefaces are set at a comfortable reading size with generous line height, and the layout reflows to a single column on small screens without loss of content or function.

The site contains one animated element, an annotation on the home page. It respects the reduced-motion preference set in your operating system, and when that preference is on, the annotation appears without movement.

Text can be resized up to two hundred percent in the browser without breaking the layout or clipping content. Nothing on this site depends on a specific screen orientation.

Advertising is served by a third party. We control where advertisements are placed and label them as advertisements, but we do not control their internal markup, and their accessibility is ultimately determined by the advertiser.

We are developing an audio version of each record. When it is published, it will be an alternative way to receive the same content, not a replacement for the written entry, and the written entry will remain the authoritative version.

Accessibility work is never finished, and parts of this site will fall short of the standard we have set. If you encounter a barrier, we want to know about it. Please tell us what page you were on, what you were trying to do, and what assistive technology you were using.

Write to us through the contact page. We aim to respond within five business days and to fix genuine barriers promptly.

Terms of Use

These terms govern your use of anomalyregistry.com. By using the site you accept them. If you do not accept them, please do not use the site.

Anomaly Registry is offered as a free documentary reference. There is no account, no subscription, and no paywall, and nothing here is offered as a professional service of any kind.

You may read, quote briefly with attribution, link to, and print records for personal, educational, and research use. This is an archive, and it is meant to be used.

You may not reproduce records wholesale, republish the register or substantial parts of it, or scrape the site systematically. In particular, you may not reproduce this content for the purpose of training generative models. Permission for other uses can be requested through the contact page and is often granted.

Original text, the record numbering system, the status taxonomy, the editorial apparatus, and the design of this site are the property of Anomaly Registry. Third-party material quoted or referenced remains the property of its owners.

We work hard to make records accurate, and we correct them when they are not. Even so, the site is provided as it is, without warranty of any kind, express or implied, including any warranty of accuracy, completeness, or fitness for a particular purpose.

Records are provisional by design. A status can change, an identification can be confirmed or overturned, and a leading explanation can be displaced by a better one. Do not treat any record as a final word, and check the review date.

To the fullest extent permitted by law, Anomaly Registry and its operator are not liable for any loss or damage arising from your use of, or reliance on, anything published here.

If you send us a correction, a source, or a suggestion, you grant us permission to use it in the register. You will not be identified in connection with it unless you ask to be credited.

Do not use the contact form to send abuse, threats, spam, or automated submissions. We may block access to anyone who misuses the site or attempts to interfere with its operation.

Outbound links are provided as references and are not endorsements. We are not responsible for the content or conduct of any site we link to.

We may revise these terms. The version published here is the version in force. These terms are governed by the laws of British Columbia, Canada, and any dispute will be heard in the courts of that province.
