Who Is Anastasia Casey? Mystery Behind Kirk Book

The assassination of American political commentator Charlie Kirk on September 10, 2025 has raised new questions after a book about the attack appeared online just one day earlier.

The book, titled The Shooting of Charlie Kirk: A Comprehensive Account of the Utah Valley University Attack, the Aftermath, and America’s Response, was credited to an author named Anastasia J. Casey. It was briefly listed on Amazon with a publication date of September 9, 2025, a day before the shooting.

The listing was later removed. According to reports, Amazon explained that the September 9 date was the result of a technical error. The company said the book was actually uploaded on September 10, after the incident took place.

Very little is known about Anastasia J. Casey. Media outlets have not been able to verify if this is a real person or a pseudonym. Some social media users who claimed to have seen or bought the book said parts of it accurately described the location and the event, while other sections were incorrect. This led to speculation that the book may have been produced quickly with the help of automated or AI tools.

Law enforcement has not found any link between the book and the assassination. Investigators remain focused on the shooting itself, while the mysterious listing continues to fuel debate online.

For now, what is confirmed is:

• The book was listed on Amazon but later taken down.
• The September 9 date was a system glitch, not proof of early publication.
• The author’s identity remains unknown.
• There is no evidence connecting the book to the attack.

The case highlights how quickly misinformation can spread online, especially during major breaking news events.
